Emily is 280 miles away from home. She is traveling back at a rate of 40 miles per hour. Determine which graphs and which equation represents Emily’s distance from home, D, after Emily travels h hours.

-40*h+280

Step-by-step explanation:

Let s define the function f which represents Emily's distance from home

at h = 0 Emily is 280 miles away from home

so f(0)=280

as she is traveling back at a rate of 40 miles per hour

f(h)=-40*h+280

the graph is below

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted
