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

14

Step-by-step explanation:

3: 9 :: 5: x+1

That means:

1:3 = 5:x+1

Which means

5(3) = x+1

Which makes 15-1 = x

Which makes 14 = x

"a" determine whether sage found the correct quotient. show your work

step-by-step explanation:

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. : )
