Step-by-step explanation:
Answer:
-6y + 6 = -2(3y - 3)
Step-by-step explanation:
-6y + 6 = -2(3y - 3)
-6y + 6 = -6y + 6
Therefore, the equation has infinitely many solutions.

Step-by-step explanation:
Answer:
x = - , x = 2
Step-by-step explanation:
To find h(g(x)) substitute x = g(x) into h(x) , that is
h(g(x))
= h(x + 1)
= (x + 1)²
= x² + 2x + 1
For h(g(x)) = 3x² + x - 5 , then
3x² + x - 5 = x² + 2x + 1 ← subtract x² + 2x + 1 from both sides
2x² - x - 6 = 0 ← in standard form
(2x + 3)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
2x + 3 = 0 ⇒ 2x = - 3 ⇒ x = -
x - 2 = 0 ⇒ x = 2
The first one is 11 and -11 because when you square them they both get 121
The second one is -7 and -1
