The equation below describes the distance, y, a train travels on a certain
route after x hours. Which value, when
written in the box, yields a rate of 120 km
per hour for the train?

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
