Jessie recently drove to visit her parents who live 570 miles away. On her way there her average speed was 25 miles per hour faster than on her way home (she ran into some bad weather). If Jessie spent a total of 19 hours driving, find the two rates (in mph). Round your answer to two decimal places, if needed. Jessie's average speed to her parents' house: mph

Jessie's average speed from her parents' house: mph

let x=speed on the way home

x+11=speed on the way to visit her parents

travel time=distance/speed

x(x+11).

..

540(x+11)+540x=18(x^2+11x)

540x+5940+540x=18x^2+198x

18x^2-882x-5940=0

divide by 18:

x^2-49x-330=0

(x+6)(x-55)=0

x=55

x+11=66

speed on the way home=55 mph

speed on the way to visit her parents = 66 mph

Step-by-step explanation:

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )

definitely a. the others have almost all data points on one side of the line.
