You automatically know that it is not A. The dot is filled in on the number line, so it must have a line under the inequality mark.

The number line says that x is greater than or equal to 2.5

Key:

gtoet means greater than or equal to

ltoet means less than or equal to.

3x + 2 gtoet 17

3x gtoet 15

x gtoet 5

This is incorrect. X is not gtoet 5.

12 + 4x gtoet 22

4x gtoet 10

x gtoet 2.5

This is correct. X is gtoet 2.5

-6x - 15 gtoet 0

-6x gtoet 15

(The sign switches in this one because you are dividing by a negative)

x ltoet 2.5

Incorrect. X is not ltoet 2.5

Let

z------> the scale factor

$z=\frac{A'C'}{AC}$

substitute the values

$z=\frac{2+8}{2}$

$z=\frac{10}{2}=5$

The scale factor is greater than 1
