Abdul and his wife are each starting a saving plan. abdul will initially set aside $50 and then add $50.85 every week to the savings. the amount a (in dollars) saved this way is given by the function a= 50.85n+50 where n is the number of weeks he has been saving . his wife will not set an initial amount side but will add $75.65 to the savings every week the amount b (in dollars) saved using this plan is given by the function b=75.65n. let t be the total amount (in dollars) saved using both plants combined right in equation relating t to n. simplify your answer as much as possible.

Explanation: We are adding two linear functions: A the original function describing Abdul's deposits, and B the deposits made by his wife.

The resulting function is a larger slope due to the added deposit rate.

b. t=-25h+3

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."
