I wil have traveled 20 miles by the moment I meet my friend

Step-by-step explanation:

Hi

We are going to use de following formula

In my case speed will be positive, so and , For my friend speed will be negative, so and . Then we can build two equations

(1)

(2)

By replacing (1) in (2)

Multiplying both sides by 5

So I wil have traveled 20 miles by the moment I meet my friend.

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x
