Because of the markings showing equal length lines 7x + 4 is double 4x or 48 is three times the length of 4x
Either solve 7x + 4 = 8x
4 = x
Or solve 48 = 12x
4 = x
Substitute back in to 7x + 4 ......MN = 7 x 4 + 4 = 32

If two distinct lines intersect, which is NOT necessarily true? A) The lines are not parallel. B) The lines are perpendicular. C) The lines form angles at the intersection. D) The intersection of the two lines is a point.
Answer:
B is not necessarily true
Step-by-step explanation:
A) This is always true
B) This is not necessarily true
When two lines intersect, they form angles at the intersection as D says, but that does not mean that the angle will always be 90 degrees as is required for the two intersecting lines to be perpendicular
C) This is always true
D) This is always true
Option B) The lines are not perpendicular is not necessarily true.
What is the Intersection of Two lines?When two lines intersect and following are the three different possibilities:
1) They are parallel, if lines are parallel they can never intersect.
2)They cross each at an angle and the point of intersection is unique that is they intersect at only one point.
3) Two lines coincide, that is every point on line 1 is a point on line 2.
Now
In option B it is given that lines are perpendicular that is the specific case of (2) When angle is 90°.
Therefore, it is not necessarily true.

What is a transformation of a shape?A point, line, or mathematical figure can be converted in one of four ways, and each has an effect on the object's structure and/or position.
Rotation does not change the shape and size of the geometry. But changes the orientation of the geometry.
Rectangle ABCD is rotated 360 around the origin.
If any object is rotated by 360 degrees about the origin. Then the position of the object does not change.
Then the coordinate of the point C' after the rotation of 360 degrees will be the same as the coordinate of C.

Greg’s gas tank is 1/3 full after he buys 2 gallons of gas it is 1/2 full how many gallons can Greg’s tank hold
Answer:
12 gallons
Step-by-step explanation:
let x be the amount tank can hold, then
[tex]\frac{1}{3}[/tex] x + 2 = [tex]\frac{1}{2}[/tex] x
Multiply through by 6
2x + 12 = 3x ( subtract 2x from both sides )
12 = x
The tank can hold 12 gallons
Greg's gas tank can hold 12 gallons of gas. We know this because when Greg's tank is 1/3 full and he buys 2 gallons of gas it becomes 1/2 full. The difference between 1/2 and 1/3 of a tank, or 1/6 of the tank, is equal to 2 gallons.
Explanation:
The subject of this question is mathematics, specifically within the scope of fractions and simple algebra. The question tells us that when Greg's gas tank is 1/3 full and he adds 2 gallons, the tank becomes 1/2 full. This tells us that the difference between 1/2 and 1/3 of the tank's capacity is equal to 2 gallons. In mathematical terms, this can be represented as 1/2 - 1/3 = 2/6 - 2/6 = 1/6. Therefore, 1/6 of Greg's gas tank equals 2 gallons. If 1/6 of the tank equals 2 gallons, the entire tank (or 6/6) would hold 12 gallons of gasoline.

Answer:
4x + y = 32
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
First obtain the equation in slope- intercept form
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (7, 4) and (x₂, y₂ ) = (5, 12)
m = [tex]\frac{12-4}{5-7}[/tex] = [tex]\frac{8}{-2}[/tex] = - 4, thus
y = - 4x + c ← is the partial equation of the line
To find c substitute either of the 2 points into the partial equation.
Using (7, 4), then
4 = - 28 + c ⇒ c = 4 + 28 = 32
y = - 4x + 32 ← in slope- intercept form
Add 4x to both sides
4x + y = 32 ← in standard form

Answer:
No triangle can be constructed with given measures.

Refer the following figure.
AB = c = 7.6 cm
AC = b = 5.4 cm
∠ABC = B = 50°
Sine rule is given by [tex]\frac{a}{sinA}=\frac{b}{sinB}=\frac{c}{sinC}[/tex]

A bag contains 2 white marbles and 7 purple marbles. Two marbles are drawn at random. One marble is drawn and not replaced. Then a second marble is drawn.
a. What is the probability of selecting a purple marble and then a white marble?
b. What is the probability of selecting two white marbles?
c. Is there a greater chance of selecting two white marbles in a row or two purple marbles in a row? Show your work
Hey there!
If we have two white marbles and seven purple marbles, our first probability is out of nine.
First of all, we have the probability of selecting a purple marble, 7/9.
Now, if we do not replace it, there are only eight marbles left. Therefore, getting a white marble is 2/8, or 1/4.
We multiply these probabilities together to get our answer to a.
7/9(1/4)= 7/36
a. 7/36
Now, let's do b. We have 2/9, and then 1/8, giving us 1/36.
b. 1/36
Now, let's calculate selecting two purple to help us with C.
We have 7/9, and then 6/8, or 3/4.
7/9(3/4)= 7/12
Since there is a majority of purple marbles, there is a C) greater probability of selecting two purple marbles in a row.

Find the value of x.
Answer:
The value of x is 4√5 ⇒ 1st answer
Step-by-step explanation:
* Lets revise the rules in the right angle triangle when we draw the
perpendicular from the right angle to the hypotenuse
- In triangle ABC
# Angle B is a right angle
# The hypotenuse is AC
# BD ⊥ AC
∴ (AB)² = AD × AC
∴ (BC)² = CD × AC
∴ (BD)² = AD × CD
∴ BD × AC = AB × BC
* Lets use one of these rules to solve the problem
- y is the perpendicular from the right angle to the hypotenuse
- x is one leg of the right angle
∵ The length of the hypotenuse = 5 + 11 = 16 units
∵ The part nearest to x = 5
* Lets use the rule (AB)² = AD × AC
∴ x² = 5 × 16 = 80 ⇒ take √ for both sides
∴ x = √80 = 4√5 units

After 3 months 5004 deposited in a savings account with simple interest had earned 162.63 in interest. What was the interest rate
Answer:
13%
Step-by-step explanation:
Please use the $ sign.
The simple interest formula is i = p*r*t, where p is the principal amount, r is the interest rate as a decimal fraction, and t is the time in years. Here, t = 1/4 year; r is unknown, p is $5004 and i is $162.63.
Writing this out with the given info, we get:
$162.63 = $5004*r*(1/4).
We can solve this for r by multiplying both sides by 4/$5004:
(4/$5004)($162.63) = (4/$5004)($5004)*r*(1/4) = r
Evaluating r, we get (4)($162.63)/$5004 = 0.13
The interest rate, r, is 0.13, or 13%.

The trick here is to notice that all 3 terms can be div. by 2:

Note that -12 factors into -3 * 4 or -4 * 3. Thus,
x^2 + x - 12 = (x-4)(x+3), and so 2x2 + 2x − 24 = 2(x-4)(x+3).

Base is a square that is 32 in
The height of one of the 4 lateral faces is 29 in

Base is L*W --> 32*32 = 1024 square inches
(1) Lateral face is 1/2*b*h = 0.5*32*29 = 464 square inches
----------------------------------------------------------------
Since the answers are about the face and/or one lateral face only, those two numbers are important. (C) is the only answer that matches
Each of the lateral faces has an area of 464 square inches , Option C is the correct answer
What is a square pyramid ?A square pyramid is a three dimensional figure , having square as the base and four triangular faces which meet at a single point called at a single point.
It is given in the question (figure is attached )
Base of the square pyramid is 32 in
The height of one of the 4 triangle is 29 in
Area of the base = 32* 32
= 1024 sq.in
Area of the lateral face (triangle ) = 1/2*b*h
= (1/2) * 32 * 29
= 464 sq. in
Therefore Option C is the correct answer , Each of the lateral faces has an area of 464 square inches.

If x is the number of 1/8 yard long pieces, then the total length is x * 1/8. We know that the total length is 3/4 yards. Therefore:
x * 1/8 = 3/4
Divide:
x = (3/4) / (1/8)
To divide a fraction, multiply by its reciprocal:
x = (3/4) * (8/1)
x = 24/4
