Describe the effect of the transformation (x, y) to (x,7y)
a. vertical stretch without reflection
b. vertical stretch with reflection

i hope this is what you were looking for.

see attached graph

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !
