X = -6 + y...so we sub in -6 + y for x in the other equation
x - 3y = 28
-6 + y - 3y = 28
-2y - 6 = 28
-2y = 28 + 6
-2y = 34
y = -34/2
y = - 17
x = -6 + y
x = -6 - 17
x = - 23
solution is (-23,-17)
Answer:
x^2+8x+15
Step-by-step explanation:
This is g(f(x)), or g(x+4). x+4 squared is x^2+8x+16, and taking 1 away from that is x^2+8x+15.
Answer:
