Frankie is comparing the monthly costs of two cellphone plans. Talk-It-Up offers unlimited talk, text, and data for $95 each month. Talk-Is-Cheap offers unlimited talk and text for $35, plus $10 per gigabyte of data per month. Write a system of equations to represent the situation using g to represent the number of gigabytes.

the answers are in the images, i received 100% on this assignment. hope this !

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
