21 divided by 7 is 3 so each candy bar equals 3 dollars

Each candy bar costs $3. you need to set up an equation...

$2 + 7x = 23 \\ 7x = 23 - 2 = 21 \\ 7x = 21 \\ x = 3$

Can anybody help me out?

You need to isolate the "x" in both inequalities

5x + 7 ≤ -3 Subtract 7 on both sides

5x ≤ -10 Divide 5 on both sides

x ≤ -2

3x - 4 ≥ 11 Add 4 on both sides

3x ≥ 15 Divide 3 on both sides

x ≥ 5

This is your simplified inequalities:

5x + 7 ≤ -3 or 3x - 4 ≥ 11 ---------> x ≤ -2 or x ≥ 5 Your answer is A

What is the scale factor of the dilation?

dusya [7]

Answer:

$\dfrac{1}{2}$

Step-by-step explanation:

It is given that triangle ACB is the preimage and triangle DFE is the image.

We need to find the scale factor of the dilation.

$\text{Scale factor}=\dfrac{\text{Side of image}}{\text{Corresponding side of preimage}}$

In the given triangles, side AC and DF are corresponding sides.

$\text{Scale factor}=\dfrac{DF}{AC}$

$\text{Scale factor}=\dfrac{6}{12}$

$\text{Scale factor}=\dfrac{1}{2}$

Therefore, the scale factor of the dilation is $\dfrac{1}{2}$ .
