Martin knows that the relationship between the number of gallons of gasoline his care uses, g, and the number of miles he travels, m, is proportional. Which equation could represent this relationship?

m = 26.5 + g

m = 26.5 + g

m = 28g

m = 28g

m = 31.5gm = 31 point 5 over g

mg = 36

m = 28g

Step-by-step explanation:

Given;

number of gallons of gasoline for Martins car, = g

the number of miles he travels = m

If the two parameters are proportional, then the following relationship can be established;

m ∝ g

introduce a constant, k

m = kg

k can be a number, from the given options , k = 28

Thus, the equation could represent this relationship is given below;

m = 28g

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

- "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."
