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

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
