Answer:

6 laps.

Step-by-step explanation:

On Monday she runs 2x + 8 miles, where x miles = the length of the trail.

On Tuesday she runs 4x + 4 miles and this is the same distance as Monday, so

2x + 8 = 4x + 4

4 = 2x

x = 2 miles which is the length of the trail.

So each day she runs 4(2) + 4 = 12 miles.

So on Saturday she runs 12/ 2 = 6 laps.

How would i solve this (-4,2); m=1/2

Setler [38]

Answer:

I'm pretty sure you have to do slope intercept form so it would be like this.

Y= mx+b

M is 1/2 and the X is given in the ordered pairs. Y is also given but it counts as the intercept so it is actually the 'B' of the equation. YOu just have to fill it in.

Y= 1/2(-4) + 2
