See the attached picture:
If you really want to figure this out you make an equation to solve for the time
let's let
x = time from Elena to Jada and
x = time from Jada to Elena
12 then the equation
12 = 5x +3x
would help figuring out their distance say for one of them
12 = x(5+3)
12/8 = x
1.5 = x
1. 5 hours they will meet up
Yes, the cost of membership is proportional to the number of months because for every 1 month it's $35 for membership fees
X= 0 or 2
When you simplify to x(x-2) = 0, you will easily see
Slope formula: y2-y1/x-x1
We can use the given points to solve.
3-(-3)/7-5
6/2
3
Best of Luck!
