Aperson leaves her camp at 7: 00 a.m. to hike back to her car. the distance from the car in kilometers y after x hours of hiking can be modeled by the linear function y = − 3 x + 18 . what does the x -intercept of the function mean.

The x axis in the function represents, the number of hours after 7:00 A.M. , the person reaches her car. The person reaches the car at 1:00 P.M.

Step-by-step explanation:

The x axis denotes the no. of hours and and the y axis denotes the distance from the car.

X Intercept is a point where the line intersects the X axis, we can easily notice the fact that at that point, y=0 ie. The person has reached his/her respective car.

The line intersects x at 6.

Therefore, a total of 6 hours are taken from the beginning of the hike.

Thus, the person reaches the car at 1:00 P.M.

2(5) = 10 feet

Step-by-step explanation:

1) 4.6x + 5x + 6x + 2x = 17.6x

2) 17.6x = 88

x = 5

Plug 5 for x in 2x.

2(5) = 10.

Hope that helps! :)
