Answer:
y = -2
Step-by-step explanation:
Step 1: Combine like terms.
Step 2: Divide both sides by 9.
Step 3: Check if solution is correct.
Therefore, y = -2.
Answer: Cross section
Step-by-step explanation: A cross section sounds just like what it is. It’s a plane that intersects a solid figure. A cross section can happen on any solid figure.
Answer:
= 2
Step-by-step explanation:
# g(x) = x^2 + 3 hence g(-2) = (−2)2+3=4+3=7
and so f(g(-2)) = f(7) = 7 - 5 = 2
Factor into (x+4)(x+2). Set each equation equal to 0, x=-4,-2
