where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
L(7,-1) and M(-2, 4)
The distance between them is

We have the final answer as

Answer:
BC=5
Step-by-step explanation:
4/10=x/x+3
4(x+3)=10x
4x+12=10x
subtract 4x from each side
6x=12
divide both sides by 6
6x/6=12/6
x=2
BC=x+3
substitute for x
BC=2+3
BC=5
First, let's make an equation as to how to find how much money they have altogether:
(M stands for the # of month)
Jaclyn: 120 + 40m
Pedro: 180 + 20m
So let's plug-in 1 for m (1 will stand for 1 month)
Jaclyn: 120 + 40 * 1 = 160
Pedro: 180 + 20 * 1 = 200
I made a table depicting how much they'll make for the next 5 months (attached below). According to that, on month 3, they will have made the same amount of money (or $240).
So they will have the same amount of money in 3 months. Hope this helps! :)
