Answer:
The answer to your question is 10 units ²
Step-by-step explanation:
To solve this problem I will use the formula
3 3
A = 1/2 3 -1 = 1/2 [ (3 x -1) + (3 x -5) + (-2 x 3) - (3 x -5) - (-2 x -1)
-2 -5 -(3 x 3)]
3 3 = 1/2 [ -3 - 15 - 6 + 15 - 2 - 9]
= 1/2 [ -20]
= 1/2|20|
= 10 units²
Sorry, I don't remember how to use the formula 1/2 b x h
Answer:
f(x) = x³+2x²-16x-32
Step-by-step explanation:
f(x) = 0 when x = -4, -2, 4
So these are the roots
Factors are (x+4)(x+2)(x-4)
f(x) = [(x+4)(x-4)](x+2)
f(x) = (x²-16)(x+2)
f(x) = x³+2x²-16x-32
To find the unit rate, use the formula
. Thus, the slope is 10/8 = 5/4
