B) y = -2x
when x = a
y = -2a
when x= 2a
y = -2(2a) = -4a
Step-by-step explanation:
<u>Step 1: Substitute x from the second equation into the second one</u>
<u>Step 2: Substitute y into the second equation</u>

Both triangles represent a translation where the triangle on the left is bigger than the one on the left which means the one on the left has to have something similar which in this case there is a side on both triangles that have a measurement which lets us start on solving the question.
Hope This Helps :)
Answer:
No graph so we'll use the quadratic formula
x^2+x-4=0
a = 1
b = 1
c = -4
x = -1 +- sqr root (1^2 - 4 * 1 * -4) / 2
x = (-1 +- sqr root (1 +16) ) / 2
x1 = (-1 + sqr root (17)) / 2
x2 = (-1 - sqr root (17)) / 2
Step-by-step explanation:
No, 43 is a prime number, so that statement is false.
