Add or subtract.
(m? - m - 3) + (m-4)
A. m^2 +m-1
B. m^2+ 2m - 7
C. m^2-7
D. m^2 -1
Answer:
C.
Step-by-step explanation:
(m^2-m-3) + (m-4)
there is no like terms for m^2 so it stays the stay.
next you add -m to m because the first m is negative they cancel out leaving nothing. lastly we add -4+-3 these added together give you -7.
so you are left with m^2 +0 -7
which simplifies to m^2 - 7
6x-5y= 0
4×-5y = -10
Answer:
the solution is (5, 6)
Step-by-step explanation:
Please reserve " × " for representing multiplication, and " x " as a variable name.
Starting with the system
6x-5y= 0
4×-5y = -10
multiply the 2nd equation by -1. This results in the system
6x - 5y = 0
-4x + 5y = 10
and combining these two equations results in
6x - 5y = 0
-4x + 5y = 10
------------------
2x = 10, or x = 5.
Substituting 5 for x in the first equation, we get
6(5) - 5y = 0, or 5y = 30. Then y = 6, and the solution is (5, 6).

Find the ratio a:b, if it is given that a+b=4a
Helpppp
Answer:
1:3
Step-by-step explanation:
if a + b = 4a then b has to be 3a
(1) + (3) = 4(1)
(2) + (6) = 4(2)
it works no matter what you plug in for a
To find the ratio a:b given that a+b=4a, we rearrange the equation to find b=3a, and then simplify the ratio to get 1:3.
Explanation:To find the ratio a:b, given that a+b=4a, we first need to express b in terms of a. This can be done by subtracting a from both sides of the equation:
a + b - a = 4a - a
b = 3a
Now that we have b expressed as 3a, we can find the ratio of a to b:
a : b = a : 3a
As we can simplify the ratio by dividing both terms by a (assuming a is not zero):
a : b = 1 : 3
Therefore, the ratio of a to b is 1:3.

THIS IS A SCIENCE QUESTION SRY
Joe was heating a test tube when it cracked. What could have caused it to crack?
A. He held the test tube directly over the flame for too long
B. He did not add water to the test tube
A or B, please explain Tks
Answer:
A. he held the tube iver the flame too long
Final answer:
The cracking of the test tube could have been caused by thermal shock due to overheating one side of the test tube by holding it over the flame for too long, or by heating an empty test tube meant for containing liquids.
Explanation:
When heating substances in a test tube, such as in a chemistry lab, it's important to take certain precautions to prevent accidents, such as the cracking of the test tube. One potential cause for a test tube to crack is thermal shock, which can occur if the test tube is heated too quickly or unevenly. This brings us to option A: 'He held the test tube directly over the flame for too long'. Holding a test tube directly in the flame can cause one side to expand more rapidly than the other due to the heat, leading to stress and cracking, particularly if the glass isn't designed to withstand rapid temperature changes. To avoid this, the test tube should be moved in and out of the flame to heat it gently and evenly, and a boiling chip can be used to prevent superheating and ensure smooth boiling.
Option B suggests another possibility: 'He did not add water to the test tube'. While not adding water to a test tube might not directly cause it to crack, if the test tube was meant to contain a liquid and was instead heated while empty, the glass could become too hot and weaken, increasing the chance of breaking. It's always important to follow specific instructions for each experiment, including whether or not to add substances to the test tube.
Both scenarios emphasize the importance of careful temperature control when heating glassware to avoid breakage from thermal stress.

In a school, 40% of the students play tennis, 24% of the students play baseball, and 58% of the students play neither tennis nor baseball. If you pick a student at random, what is the probability that the student plays both tennis and baseball?
Answer:
0.22
Step-by-step explanation:
If 58% of the students play neither tennis nor baseball, then;
100 - 58 = 42% play tennis, baseball or both sports. Now,
Pr ( tennis ∪ baseball) = Pr ( tennis) + Pr ( baseball) - Pr ( tennis ∩ baseball)
42% = 40% + 24% - Pr ( tennis ∩ baseball)
Pr ( tennis ∩ baseball) = 40 + 24 - 42
Pr ( tennis ∩ baseball) = 22%
Therefore, If you pick a student at random the probability that the student plays both tennis and baseball is 0.22
Which polynomial could have the following graph?
ANSWER
y=(x+3)(x-1)(x-5)
EXPLANATION
The given polynomial has x-intercepts at x=-3,x=1,x=5
These are called the zeros of this polynomial.
We can use the factor theorem to obtain the polynomial in factored form.
The polynomial in factored form is of the form
y=a(x+3)(x-1)(x-5)
The polynomial rises on the left and keep rising on the right.
This implies that, the 'a' is positive.
Therefore
y=(x+3)(x-1)(x-5)
The correct choice is the first option.
Answer: y = (x + 3)(x - 1)(x - 5)

The circumference of a circle measures 12.56 inches. What is the measure of the radius of the circle?
A. 2in
B. 3.14in
C. 4in
D. 6.28in
PLEASE HELP!!
The radius of the circle with a circumference of 12.56 inches is 2 inches, calculated using the formula C = 2πr and rearranging it to find the radius.
Explanation:The circumference of a circle is given by the formula C = 2πr, where C stands for the circumference and r stands for the radius of the circle. The value of π (pi) is approximately 3.14159. Given the circumference of the circle as 12.56 inches, you can find the radius by rearranging the equation to r = C / (2π).
Now, let's calculate the radius using the given circumference:
r = 12.56 inches / (2 × 3.14159)
r = 12.56 inches / 6.28318
r = 2 inches
Therefore, the measure of the radius of the circle is 2 inches, which corresponds to option A.
To find the measure of the radius of the circle given its circumference, we can use the circumference formula of a circle, which is:
\[ C = 2 \pi r \]
Where \( C \) is the circumference, \( \pi \approx 3.14159 \), and \( r \) is the radius of the circle.
Now, we know the circumference (\( C \)) is 12.56 inches. We can solve for the radius (\( r \)) by rearranging the formula:
\[ r = \frac{C}{2 \pi} \]
Plugging the given circumference into the equation, we get:
\[ r = \frac{12.56}{2 \times \pi} \]
\[ r = \frac{12.56}{2 \times 3.14159} \]
\[ r = \frac{12.56}{6.28318} \]
\[ r = 2 \]
Rounding the result to two decimal places as may be required for some comparisons, we still get \( r = 2.00 \) inches.
Therefore, the measure of the radius of the circle is 2 inches, which corresponds to option A.

Answer:

Use FOIL: (a + b)(c + d) = ac + ad + bc + bd
and i² = -1
[tex](3+i)(4+2i)\\\\=(3)(4)+(3)(2i)+(i)(4)+(i)(2i)\\\\=12+6i+4i+2i^2\qquad\text{combine like terms}\\\\=(12-2)+(6i+4i)\\\\=10+10i[/tex]
Answer:
11 + 10i
Step-by-step explanation:
Note that we're multiplying two binomials here, and thus may use the FOIL method. This requires four multiplications, as follows:
3*4 + 3*2i + 4i - 1 (The last term is 1 because i(i) = i^2 = -1.)
Simplifying, we get:
12 + 6i + 4i -1, or:
11 + 10i

1 degree is [tex]\dfrac\pi{180}[/tex] radians. So 14 degrees is [tex]\dfrac{14\pi}{180}=\dfrac{7\pi}{90}[/tex] rad.
Easy way to remember this: one complete revolution in a circle is 360 degrees. But it's also [tex]2\pi[/tex] radians. So the conversion rate is

x = 35
x= 19
x can not be determined from the information given
x = 27.25
Answer:
x=35
Step-by-step explanation:
These are alternate interior angles. Since a and b are parallel, they are equal

Answer:
The rational function that is graphed is B
The rational function which is graphed below is:
Option: B
B. [tex]F(x)=\dfrac{x}{(x-1)(x+1)}[/tex]
Step-by-step explanation:From the graph of the function we see that the graph has vertical asymptote at x=1 and x= -1
Also, we know that while finding the vertical asymptote of the rational function we substitute denominator equal to zero and the values of such x will be the vertical asymptote.Also, if the line y=0 act as a horizontal asymptote if the degree of polynomial in numerator is smaller than in the denominator.The function in which above two property hold true is:
B. [tex]F(x)=\dfrac{x}{(x-1)(x+1)}[/tex]
( since in option: A
If denominator equal to 0 then x=0 and -1
This means that the vertical asymptotes are 0 and -1 .
In option: C
If denominator is equal to zero.
Then x=0 and 1
This means that the vertical asymptotes are 0 and 1
In option: D
When denominator=0
then x=0
This means that the vertical asymptote is at x=0
which is false )

What is the axis of symmetry for f(x) = x2 + 4x + 6
Answer:
x = -2
Step-by-step explanation:
In order to find the axis of symmetry, we will have to find the x-value of the vertex.
Vertex = (-b/2a, f(-b/2a))
In x² + 4x + 6,
a = 1 , b = 4 , c = 6
Vertex = (-4/2,f(-4/2))
Vertex = (-2,f(-2))
We have found the x-value of the vertex which is -2.
Hence, line/axis of symmetry is x = -2
The axis of symmetry for f(x) = [tex]x^2 + 4x + 6[/tex] is -2.
Given that,
The equation is f(x) = [tex]x^2 + 4x + 6[/tex].Here we need to find the axis of symmetry.Based on the above information, the calculation is as follows:
Here we have to determine the x-value of the vertex.
[tex]Vertex = (-b\div 2a, f(-b\div 2a))[/tex]
Now as per the given equation i.e [tex]x^2 + 4x + 6[/tex]
Here,
a = 1 , b = 4 , c = 6
Now
[tex]Vertex = (-4\div 2,f(-4\div 2))[/tex]
= (-2,f(-2))
= -2
Therefore we can conclude that the axis of symmetry for f(x) = [tex]x^2 + 4x + 6[/tex] is -2.

explain how u would use the integer tiles to find the quotient of -15 and 3
Answer:
(-15)/3 = -5
Step-by-step explanation:
(-15)/3
Assume that your positive tiles are yellow, and your negative tiles are red.
The question is asking, "if you take 15 red tiles and split them into three equal groups, how many will you have in each group?"
How can you model the first value of -15? With 15 red tiles.
Let’s model how to divide the tiles into three equal groups by moving one tile at a time into three separate groups until all 15 tiles have been moved.
Step 1.
Start with 15 red tiles, as in the first picture.
Step 2.
Start by moving tiles one at a time to begin creating three new groups.
The middle picture shows the situation after you have moved the first three tiles.
Step 3.
Continue moving tiles one at a time from the original group and stacking them evenly in the three new groups until you have no more tiles to move.
The third picture shows the situation when you have finished.
How many red tiles are in each group? There are five.
Is the answer positive or negative? The answer is negative, because there are five red negative tiles in each group.
Conclusion? (-15)/3 = -5
Integers are expressions without decimals.
The result of the quotient of -15 and 3 is: -5
The expression is given as:
[tex]\mathbf{\frac{-15}{3}}[/tex]
To do this using integer tiles, we start by isolating the negative sign
[tex]\mathbf{\frac{-15}{3} = (-)\frac{15}{3}}[/tex]
Then divide 15 by 3 (see attachment for illustration of the division)
From the attached figure, we have:
[tex]\mathbf{\frac{15}{3} = 5}[/tex]
Substitute 5 for 15/3 in [tex]\mathbf{\frac{-15}{3} = (-)\frac{15}{3}}[/tex]
So, we have:
[tex]\mathbf{\frac{-15}{3} = (-)5}[/tex]
Remove bracket
[tex]\mathbf{\frac{-15}{3} = -5}[/tex]
Hence, the result of the expression is: -5

Points to remember
solution of a quadratic equation ax² + bx + c = 0
x = [-b ± √(b² - 4ac)]/2a
It is given that, x² + 9x + 10 = 0.
To find the solution
Here a = 1, b= 9 and c = 10
x = [-b ± √(b² - 4ac)]/2a
= [-9 ± √(9² - 4*1*10)]/2*1

Answer:
The value of c is 10.9 ⇒ 3rd answer
Step-by-step explanation:
* Lets study the problem
* In ΔABC
- a, b, c are the lengths of its 3 sides, where
# a is opposite to angle A ⇒ BC
# b is opposite to angle B ⇒ AC
# c is opposite to angle C ⇒ AB
- m∠C = 68°
- a = 8 ⇒ side BC
- b = 11 ⇒ side AC
- Find the value of c ⇒ side AB
* We have the length of two sides and the measure of the
including angle between them and we want to find the
length of the side opposite to this angle then the cosine
rule is the perfect way
∵ c² = a² + b² - 2ab cos(C)
∵ a = 8 , b = 11 and m∠C = 68°
∴ c² = (8)² + (11)² -2(8)(11) cos(68°)
∴ c² = 119.069 ⇒ take √ for both sides
∴ c = 10.9 units
* The value of c is 10.9
