Homework due before 7pm

Answers:

8.8 miles on the first day

5.2 miles on the second day

Explanation:

f = number of miles walked on the first day

f - 3.6 = number of miles walked on the second day, since they traveled 3.6 miles less compared to the first day.

The two expressions f and f-3.6 must add to 14 as this is the total distance over the two days.

(first day)+(second day) = 14

(f) + (f-3.6) = 14

2f-3.6 = 14

2f = 14+3.6

2f = 17.6

f = (17.6)/2

f = 8.8

They walked 8.8 miles on the first day and f-3.6 = 8.8-3.6 = 5.2 miles on the second day.

As a check,

(first)+(second) = (8.8) + (5.2) = 14

so the answer is confirmed.

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
