If x+y = z and y−z=x which of the following must be equal to z?
(A) 0 (B) x (C) y (D) −x (E) –y
ANSWER
(C) y
EXPLANATION
We have two equations:
The first one is
[tex]x + y = z...(1)[/tex]
The second equation is
[tex]y - z = x...(2)[/tex]
Let us make z the subject of this second equation:
[tex] \implies \: -x +y = z...(3)[/tex]
We now add equation (1) and (3) to get:
[tex](-x + x) + (y + y) = z + z[/tex]
We simplify to get:
[tex]0+2y= 2z[/tex]
[tex]2y= 2z[/tex]
Divide throu by 2.
[tex] \frac{2y}{2} = \frac{2z}{2} [/tex]
[tex]y= z[/tex]
[tex] \therefore \: z = y[/tex]
The correct answer is C
A pair of ordinary dice is rolled. What is the probability that each die will show a number higher than 4. 1. (1/36) 2. (1/12) 3. (1/6) 4. (1/4) 5. (1/3)
Answer:
the answer is 1/12
Step-by-step explanation:
it is 1/12 because if there are only a pair you would have 2 dice. and since each die has numbers all the way up to 6 all you have to do is add them. and don't count all the numbers. like add 1+2+3+4+5+6. that's just plain wrong just do add the highest number on each die (6+6)
Indicate in standard form the equation of the line through the given points. K(6, 4), L(-6, 4)
y=4
the values of x changes while the y doesn't so it's y=4
Answer:
[tex]y=4[/tex]
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
[tex]y=mx+b[/tex]
Where "m" is the slope and "b" is the y-intercept.
The equation of the line in Standard form is:
[tex]Ax + By =C[/tex]
Where A, B, and C are integers.
We can find the slope of this line with this formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Given the points K(6, 4) and L(-6, 4), we get:
[tex]m=\frac{4-4}{-6-6}=0[/tex]
Substituting the value of "m" and the coordinates of any point on the line into the equation and solving for "b", you get:
[tex]4=0(6)+b\\b=4[/tex]
Therefore, the equation of this line is:
[tex]y=4[/tex]

Answer:
137°Step-by-step explanation:
The pentagon RSTYZ is a regular polygon. Therefore all angles are congruent.
If m∠RST = 108°, then m∠STY = 108°.
We have the equation:
m∠UTY + m∠STY + m∠STU = 360°.
Substitute m∠STY = 108° and m∠UTY = 115°.
115° + 108° + m∠STU = 360°
223° + m∠STU = 360° subtract 223° from both sides
m∠STU = 137°

Find the area of a square whose perimeter is equal 36m
Answer: Area of Square = 81m^2
Step-by-step explanation:
To find the area of a square you just need to know the side length on one side, and since we know that the perimeter is 36, and all sides of a square are equal we can divide 36/4, to get 9 is your side length.
Now to actually find the area you can just square your side length, so basically 9x9, which gives you 81, your answer!!
Answer:
Area = 81m^2
Step-by-step explanation:
Square has 4 equal sides so 36/4 = 9
9(9) = 81

A bank loaned out $17,500, part of it at the rate of 10% annual interest, and the rest at 14% annual interest. The total interest earned for both loans was $2,170.00. How much was loaned at each rate?
$ ______was loaned at 10% and
$______ was loaned at 14%.
Answer:
$7 000 was loaned at 10 % and
$10 500 was loaned at 14 %
Step-by-step explanation:
Let x = amount loaned at 10 %
Then 17 500 - x = amount loaned at 14 %
0.10x = interest on 10 % loan
0.14(17 500 - x) = interest on 14 % loan
2170.00 = total interest
[tex]\begin{array}{rcl}0.10x + 0.14(17 500 - x) & = & 2170.00\\0.10x + 2450 - 0.14x & = & 2170.00\\2450 - 0.04x & = & 2170.00\\-0.04x & = & -280\\\\x & = & \dfrac{-280}{-0.04}\\\\x & = & \mathbf{7000}\\\\\end{array}[/tex]
$7000 was loaned at 10 % and
$10 500 was loaned at 14 %
Check:
\[tex]\begin{array}{rcl}0.10\times 7000 + 0.14(17 500 - 7000) & = & 2170\\700 + 0.14(10 500) & = & 2170\\700 + 1470 & = & 2170\\2170 & = & 2170\\\end{array}[/tex]

What is the area of the irregular polygon shown below?
O
A. 65 sq. units
O
B. 49 sq. units
O
C. 105 sq. units
O
D. 35 sq. units
Answer:
Option B: 49 square units.
Step-by-step explanation:
The irregular polygon consists of a rhombus a square.
Area of rhombus = 0.5*(product of diagonals).
Area of square = length * length = l^2.
The diagonals of the rhombus measure 8 units and 6 units respectively. The diagram shows the length of half of the diagonals, so doubling both the lengths gives us the required lengths. The side of the square measures 5 units. Substituting all the information in the formula:
Total Area = Area of rhombus + Area of square.
Total Area = 0.5*8*6 + 5^2.
Total Area = 24 + 25
Total Area = 49 square units.
Therefore, Option B is the correct answer!!!

Answer:
The third quartile is:
[tex]Q_3=29[/tex]
Step-by-step explanation:
First organize the data from lowest to highest
4, 5, 10, 12, 14, 16, 18, 20, 21, 21, 22, 22, 24, 26, 29, 29, 33, 34, 43, 44
Notice that we have a quantity of n = 20 data
Use the following formula to calculate the third quartile [tex]Q_3[/tex]
For a set of n data organized in the form:
[tex]x_1, x_2, x_3, ..., x_n[/tex]
The third quartile is [tex]Q_3[/tex]:
[tex]Q_3=x_{\frac{3}{4}(n+1)}[/tex]
With n=20
[tex]Q_3=x_{\frac{3}{4}(20+1)}[/tex]
[tex]Q_3=x_{15.75}[/tex]
The third quartile is between [tex]x_{15}=29[/tex] and [tex]x_{16}=29[/tex]
Then
[tex]Q_3 =x_{15} + 0.75*(x_{16}- x_{15})[/tex]
[tex]Q_3 =29 + 0.75*(29- 29)\\\\Q_3 =29[/tex]
Answer:

Origami is the Japanese art of paper folding. The diagram below represents
an unfolded paper kabuto, a samurai warrior's helmet. Which of the following
are pairs of congruent segments?
Check all that apply.
Answer:
The correct options are B, C and D.
Step-by-step explanation:
It is given that the figure is a Japanese art of paper folding. It means the figure have many lines of symmetry (i.e., AK, IO, CM and NF).
From the figure it is clear that HV is larger than GW, so segment HV and GW are not pairs of congruent segments.
Therefore option A is incorrect.
[tex]\overline{IJ}\cong \overline{LM}[/tex] (AK is line of symmetry)
[tex]\overline{AB}\cong \overline{AP}[/tex] (AK is line of symmetry)
[tex]\overline{BC}\cong \overline{PO}[/tex] (AK is line of symmetry)
Therefore the correct options are B, C and D.
From the figure it is clear that PO is smaller than ON, so segment HV and GW are not pairs of congruent segments.
Therefore option E is incorrect.

When Harold wrote his equation, the point he used was (7,3).
When Harold wrote his equation, the point he used was (0, 7).
When Harold wrote his equation, the point he used was (7,0).
When Harold wrote his equation, the point he used was (3, 7).
Answer:
When Harold wrote his equation, the point he used was (7,0).
Step-by-step explanation:
we know that
The equation of a line into point slope form is equal to
[tex]y-y1=m(x-x1)[/tex]
where
(x1,y1) is the point
m is the slope
In this problem we have
[tex]y=3(x-7)[/tex]
therefore
the point is (x1,y1)=(7,0)
the slope is m=3
Maria solved an equation as shown below. What is the solution to Maria’s equation?
Answer:
[tex]x=19[/tex]
Step-by-step explanation:
We have the following equation
[tex]3(x+6)=5(x-4)[/tex]
Notice that in this equation the variable that we want to find is x.
Then the equation for the variable x must be solved
After applying the distributive property and simplifying the equation Maria obtained the following result
[tex]19=x[/tex]
This is the same as:
[tex]x=19[/tex]
That means that the value of x for which equality is met is [tex]x = 19[/tex]. Therefore the solution of the equation is [tex]x = 19[/tex]
You need to put oil into the gearbox of a rebuilt machine tool. The gearbox holds 16.3 liters of oil but the only oil you have is in 1-quart containers. How many of the one quart containers of oil will you need to fill the gearbox with 16.3 liters of oil
Answer: You will need 18 containers of 1-quart to fill the gearbox with 16.3 liters of oil.
Step-by-step explanation:
Knowing that you have 1-quart containers, you need to make the conversion from quarts to liters. This is:
[tex]1\ quart=0.946\ liters[/tex]
Now, since the gearbox holds 16.3 liters of oil, you can divide the volume of oil the gearbox holds by the volume of a container (which is 0.946 liters or 1-quart) to calculate how many containers of 1-quart you will need to fill the gearbox with 16.3 liters of oil.
[tex]number\ of\ containers=\frac{16.3\ liters}{0.946\ liters}=17.2[/tex]
Based on the result, you will need 18 containers of 1-quart to fill the gearbox with 16.3 liters of oil.
You will need 17 one-quart containers of oil to fill the 16.3-liter gearbox.
Explanation:To determine how many 1-quart containers of oil you will need to fill the 16.3-liter gearbox, we can convert the 16.3 liters to quarts by using the conversion factor of 1 liter = 1.05668821 quarts. So, 16.3 liters would be approximately 17.229 quarts. Since each 1-quart container holds exactly 1 quart of oil, you will need 17 of the 1-quart containers to fill the gearbox with 16.3 liters of oil.

1. There were 36,000 people at a horse race in Lexington, Kentucky. The day's
receipts were $250,000. The only two types of seats available were clubhouse
or grandstand seats. How many people paid $12.00 for clubhouse seats and
how many people paid $5.00 for grandstand seats? Only an algebraic solution
will earn credit. State what any variables represent by writing a "let statement”.
Answer:
10000 people paid $12.00 each for clubhouse seats and26000 people paid $5.00 each for grandstand seats.Step-by-step explanation:
The question is asking for a system of equations, which make explanations easy. :)
Define the variables. Setting [tex]x[/tex] to the number of clubhouse seats sold and [tex]y[/tex] to the number of grandstand seats sold will be sufficient. The "let statement[s]" will be:
Let [tex]x[/tex] be the number of clubhouse seats sold.Let [tex]y[/tex] be the number of grandstand seats sold.The number of equations shall be no less than the number of variables for the solution to be unique. There are two variables. It will take at least two equations to find a unique solution.
Everyone at the race need a seat. The number clubhouse seats plus the number of grandstand seats shall be the same as the number people at the race. There were 36,000 people. Therefore the first equation shall be:
[tex]x + y = 36000[/tex].
Every clubhouse seat will add $12.00 to the receipt. [tex]x[/tex] clubhouse seats will add $[tex]12\;x[/tex] to the receipt. Similarly, [tex]y[/tex] grandstand seats will add $[tex]5\;y[/tex] to the receipt. The two values shall add up to $250,000.
Drop the dollar sign to get the second equation:
[tex]12\;x +5\;y =250000[/tex].
Hence the system:
[tex]\displaystyle \left\{\begin{aligned}& x + y = 36000 && \textcircled{\raisebox{-0.9pt}1}\\ & 12\;x + 5\;y = 250000 && \textcircled{\raisebox{-0.9pt}2}\end{aligned} \phantom{\small credit for the raisebox hack: tex[dot]stackexchange[dot]com/questions/7032/good-way-to-make-textcircled-numbers}[/tex].
Solve this system.
The first non-zero coefficient in equation [tex]\textcircled{\raisebox{-0.9pt}1}[/tex] is already one. That's the coefficient for [tex]x[/tex]. Use multiples of equation [tex]\textcircled{\raisebox{-0.9pt}1}[/tex] to get rid of [tex]x[/tex] in other equations (equation [tex]\textcircled{\raisebox{-0.9pt}2}[/tex] in this case.)
[tex]-12[/tex] times equation [tex]\textcircled{\raisebox{-0.9pt}1}[/tex] is
[tex]-12 \;x - 12\;y = -432000[/tex].
Add [tex]-12\times \textcircled{\raisebox{-0.9pt}1}[/tex] to [tex]\textcircled{\raisebox{-0.9pt}2}[/tex] to get:
[tex]0\;x + -7\;y = -182000[/tex].
Divide both sides by -7 to get:
[tex]y = 26000[/tex].
Add -1 times this equation to equation [tex]\textcircled{\raisebox{-0.9pt}1}[/tex] to get:
[tex]x = 10000[/tex].
That is:
[tex]\displaystyle \left\{\begin{aligned}&x = 10000\\&y = 26000\end{aligned}[/tex].
In other words,
10000 clubhouse seats were sold, and26000 grandstand seats were sold.Evaluate a + 6 for a = 10?

Find the indicated term of the given geometric sequence. a1 = 14, r = –2, n = 11
Answer:
[tex]a_{11} = 14336[/tex]
Step-by-step explanation:
The general formula for the twelfth term of a geometric sequence is:
[tex]a_n = a_1(r)^{n-1}[/tex]
Where [tex]a_1[/tex] is the first term and r is the common ratio
In this case we know that:
[tex]a_1 = 14\\r=-2[/tex]
The equation is:
[tex]a_n = 14(-2)^{n-1}[/tex]
So for [tex]n = 11[/tex] we look for [tex]a_{11}[/tex]
[tex]a_{11} = 14(-2)^{11-1}[/tex]
[tex]a_{11} = 14(-2)^{10}[/tex]
[tex]a_{11} = 14336[/tex]
Answer:
[tex]11^{th}[/tex] term = 14336
Step-by-step explanation:
We are given the first term [tex] a _ 1 = 1 4 [/tex] and common ratio [tex] r = - 2 [/tex] of a geometric sequence and we are to find the [tex]11^{th}[/tex] term of this sequence.
We know that the formula to find the [tex]n^{th}[/tex] term in a geometric sequence is given by:
[tex]n^{th}[/tex] term = [tex] a r ^ { n - 1 } [/tex]
Substituting the given values in the above formula:
[tex]11^{th}[/tex] term = [tex]14 \times(-2)^{11-1}[/tex]
[tex]11^{th}[/tex] term = [tex]14 \times(-2)^{10}[/tex]
[tex]11^{th}[/tex] term = 14336
Which formula can be used to determine the total number of different eight-letter arrangements that can be formed using the letters in the word "CLIMBING"?
The word "climbing" has 8 letters, so there are [tex]8![/tex] permutations of all the letters.
Nevertheless, the letters are not unique: there are 2 I's. This means that, if we start from a given word and we exchange the positions of the two I's, we'd still get the same word. So, we have to divide the number of possible permutations by [tex]2![/tex], because for any given permutation there are two identical words, given by the interchange of the I's.
So, the number of possible words is
[tex]\dfrac{8!}{2!} = \dfrac{8\times7\times6\times5\times4\times3\times2}{2}=8\times7\times6\times5\times4\times3=40320[/tex]

given the quadratic function f(x)= 3x²- 6x + 1
express the quadratic function f(x) in the form a(x+p)²+q, where a, p and q are constants. determine whether f(x) has a maximum or minimum value and state the value.
Answer:
It's minimum value
and the value is :(1 , -2)
Answer:
see explanation
Step-by-step explanation:
Given
f(x) = 3x² - 6x + 1
To express in vertex form
f(x) = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Use the method of completing the square
The coefficient of the x² must be 1, so factor out 3
f(x) = 3(x² - 2x) + 1
add/subtract ( half the coefficient of the x- term )² to x² - 2x
f(x) = 3(x² + 2(- 1)x + 1 - 1) + 1
= 3(x - 1)² - 3 + 1
= 3(x - 1)² - 2 ← in vertex form
with vertex = (1, - 2)
To determine if vertex is a max/ min
• If a > 0 then minimum
• If a < 0 then maximum
here a = 3 > 0 ⇒ minimum at (1, - 2)
The minimum value is the y- coordinate of the vertex, that is
minimum value = - 2
