5 cm

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

[tex]\dfrac{x}{40}=\dfrac{4}{32}[/tex]               cross multiply

[tex]32x=(40)(4)[/tex]

[tex]32x=160[/tex]             divide both sides by 32

[tex]x=5[/tex]

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
