Margo has $100 in her bank account and is saving $50 per month. Jon has $75 in his bank account and is saving $100 per month. Which of the following systems of equations would tell how many months, x, it will take for Margo and Jon to have the same amount of money, y? y=100 + 75% y = 75+. 752 y=100 + 503 y = 75+. 1000 y = 75 + 50.2 y = 75+752 y=100 + 50% y = 75+.50.2​

- "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."

ummm seems that u didnt post the attachement !

what
