Answer:
C is the answer
Step-by-step explanation:
because if you move the triangle two to the right then X=1
X=1 means the line is up and down going thought x=1
and if that line you make you reflect across it would be C
Answer: -8
Step-by-step explanation:
1. Combine like terms.
-x - 3 = (x - 3x ) + ( 5 - 16)
2. Simplify.
-x - 3 = -2x - 11
3. To balance the equation, add 2x on both sides.
-x - 3 + 2x = -2x - 11 + 2x
4.
x - 3 = - 11
Solve for x, which gives you -8.
Answer:
Option D, Yes, Devon should have evaluated f(3)
Step-by-step explanation:
f(x) = x^3 + x^2 − 10x + 8
<u>Step 1: Evaluate using F(3) NOT f(-3)</u>
f(3) = 3^3 + 3^2 - 10(3) + 8
f(3) = 27 + 9 - 30 + 8
f(3) = 14
Since the factor is (x - 3) the x value is x - 3 + 3 = 0 + 3 -> x = 3 not x = -3
Answer: Option D, Yes, Devon should have evaluated f(3)
