Answer:
x=2, x=-1
Step-by-step explanation:
f(x) = x^2 − x − 2
Set equal to zero
0 = x^2 − x − 2
Factor
What 2 numbers multiply to -2 and add to -1
-2*1 = -2
-2+1 =1
0=(x-2) (x+1)
Using the zero product property
x-2 =0 x+1 =0
x=2 x=-1

Answer:
W = 415
Step-by-step explanation:
Is means equals and of means multiply
W = 125% * 332
Change to decimal form
W = 1.25 *332
W = 415
9514 1404 393
Answer:
y = -5x³
Step-by-step explanation:
The point of inflection of the parent cubic function f(x) = x³ is at the origin, the same place it is shown on the graph. So, there is no translation involved in creating the graph.
We know the parent function gives f(1) = 1, but here, we have (x, y) = (1, -5). This suggests a vertical scale factor of -5. So, the transformed function is ...
y = -5x³
Area of a triangle = (h × b) ÷ 2, where h is height and b is the base.
7.1 × 28 = 198.8
198.8 ÷ 2 = 99.4
The area of this triangle is 99.4 yd²
