Answer:
Here's what I got. First of all, did you meant y=mx+b+mx+mxy+mx=b, because that's undefined, or did you meant y=mx+b+mx+mx, which is b=−3mx+y.
Answer: After 5 hours, Mary will be at the break even point.
To answer this question, we need to find the time when the cost equals the revenue.
Therefore, set our equations equal to each other and solve.
20 + 30h = 10h^2 - 80
0 = 10h^2 - 30h - 100
0 = h^2 - 3h - 10
0 = (h - 5)(h + 2)
Our solutions are h = 5 or h = -2. Only 5 hours makes sense in the context of this problem.

1.first solve the hypotenuse of (12 squared+16 squared) = (Hy squared)
2.then find the square root of the Hypotenuse


Answer:
10x + 7y = 2
Step-by-step explanation:
Slope = (6 + 4)/(-4 - 3) = -10/7
Equation:
y + 4 = -10/7(x - 3)
7(y + 4) = - 10(x - 3)
7y + 28 = -10x + 30
10x + 7y = 30 - 28
10x + 7y = 2
