Question

Y=x^2-15x+26
y=-3x-6​

Answer 1

(4,−18) and (8,−30)

Explanation:

I just got it correct

Answer 2

x = 4

x = 8

Explanation:

I will solve this using the substitution method.

y = x² - 15x + 26

y = -3x - 6

Equal the answers to each other.

x² - 15x + 26 = -3x - 6

x² - 12x + 32 = 0

(x - 4) (x - 8)

x = 4

x = 8
