4(7-x) = 5(x+2)
you would give 4 and 5 to everything in the parenthesis
28-4x = 5x+10
then subtract 10 on each side
28-4x = 5x+10
-10 -10
18-4x = 5x
then add 4x on each side
18-4x = 5x
+4x +4x
18 = 9x
x = 2

<em>ANSWER:</em>

<h2>x=2</h2>

<em>STEP:</em>

Multiply the parenthesis by the number before.

28-4x=5x+10

Add 4x to both sides.

28-4x=5x+10

28=9x+10

Subtract 10 from both sides.

18=9x

Divide both sides by 9.

2=x

A figure has vertices at L(3,3), M(2,4), and N(−1,0). After a transformation, the image of the figure has vertices at L′(2,−5),
alexandr402 [8]

The transformation was a reflection over the line x = -0.5

And the image and preimage can be seen in the graph below.

<h3>How to identify the preimage and image?</h3>

First, the original vertices are:

L(3, 3)

M(2, 4)

N(-1, 0)

3 vertices means that our figure is a triangle.

Now, the transformed vertices are:

L'(2, -5)

M'(3, -4)

N'(-1, 1)

And the graph of both sets can be seen below.

Now we can try to identify the transformation.

Now, notice that all the points (L, M, N, L', N', M') are equidistant to the horizontal line x = -0.5

This is a clear implication that the transformation was a reflection over the line x = -0.5

Can't figure out how to set up and check to see if right. 8/11(n-10)=64
strojnjashka [21]

Answer:

Step-by-step explanation:

\frac{8}{11}(n-10)=64\\\\\frac{8(x-10)}{11}=64\\ 8(x-10) = 64(11)\\8(x-10) = 704\\8x-80 = 704\\8x= 704+80\\8x=784\\\\\frac{8x}{8}=\frac{784}{8}  \\x=98
