Last month maria high the 5 mile mountain trail a number of times and she hiked the 10 mile canal trail several times. let x represent the number of times she hiked the 5 mile trail, and y represent the number of times she hi the 10 mile trail. if she had a total of 90 miles, which equation can be used to find the number of times maria hiked each trail?

Alright, lets get started.

Maria hiked the 5 mile Mountain Trail a number of times and she hiked the 10 mile canal trail several times.

x times she hiked 5 mile mountain.

So, number of mils she hiked for 5 miles will be = 5 x

Similarly,

y times she hiked 10 mile canal,

So, number of miles she hiked for canal = 10 y

So, total number of miles she hiked =

But as per question given,  she had a total of 90 miles

It means

Dividing this equation with 5

So, the equation is :   Answer

Hope it will help :)

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

answer is (b.
