If (x) = 2х2 + 1 and g(x) = х2 -7, find (f+ g)(x). А. х2 + 8
В. 3х2 + 8
C. 3х2 - 6
D. х2 - 6

C

- "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."

so what is the problem what are they asking you to solve

step-by-step explanation:

sorry man i accidentally pressed yes my bad

step-by-step explanation:

i believe that the answer is

b. y-1=-2(x-4)

hope this !
