13.) 14y - 59 = 9y + 1 (subtract 9y on both sides)

5y - 59 = 1 (add 59 on both sides)

5y  = 60 (divide by 5 on both sides)

y = 12

7x - 3 = 60 (add 3 on both sides)

7x = 63 (divide by 7 on both sides)

x = 9

HOPE THIS HELPS YA!!

I added a screenshot from my geometry note which I thought would be helpful!!

i can't read the graph

step-by-step explanation:

- "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."
