The graph of a system of parallel lines will have no solutions. (1 point) select one: a. always b. sometimes c. never

Always

Step-by-step explanation:

The solution to a system of equations graphically is at the point of intersection of the graphs.

If the lines are parallel then they never intersect and so there is no solution.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
