The smaller triangle was dilated to form the larger triangle. what is the value of x? 10 11 14 15

Without an illustration, it is impossible to figure this out. I apologize.

14

Explanation:

I took the test, but next time, please show the graph. The graph below is the one from the test on E d g e n u i t y

yes

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
