Answer:
14 elliptical machines
Step-by-step explanation:
t = # of treadmills
e = # of elliptical machines
t + e = 38
t = e + 10
Substitute:
e + 10 + e = 38
2e = 28
e = 14
To find Y intercept
You do y2-y1/ x2-x1
Your y2 is 12, y1 is 2
Your x2 is 2 , x1 is 3
So 12-3/2-3
12-3 is 9
2-3=-1
9/-1 is -9
So your slope is -9
P-6=19; p=13
so you just plug the value of P into the problems P and solve the equation
(13) - 6 = 19
7=19
so...that's incorrect because 7 can't equal 19 making the problem No solution. if that's wrong then idk what they're teaching in math any more...
