Question

8. The system of equations below describes the relationship between the time (t), in seconds,

two objects have been traveling and each object's velocity (v), in feet per second.
V = -32t
v=-32t + 16
Based on the system of equations, which statement about the velocity of the objects is true?

A.The objects never travel at the same velocity.
B. The objects always travel at the same velocity.
C. The objects travel at the same velocity only after they have been traveling for second.
D. The objects travel at the same velocity only after they have been traveling for second.

Answer 1

Answer: A

Explanation:

Joe walks on a treadmill at a constant rate. The equation d=4t describes the relationship between t, the time he walks in hours, and d, the distance he walks in miles. Which of the graph best describes the relationship?

The equation d=4t is a linear equation.

When t=1, d=4 X 1 =4

When t=2, d=4 X 2 =8

The correct graph that satisfies this pair is A (as seen in the diagram) (sorry if i got it wrong)
