What are the vertex and x-intercepts of the graph of the function below? y =(x-4)(x+2)
A. Vertex: (-4, 2); Intercepts: x = 3,-3
B. Vertex: (1,-5); Intercepts: x = -4,2
C. Vertex: (1,-9); Intercepts: x = 4,-2
D. Vertex: (1,9); Intercepts: x = -4,-2

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
