Y = mx + b is slope intercept form
x = -10
y = 8
m = 6
1. Solve for b
8 = (6)(-10) + b
b = 68
2. Plug m and b back into your slope intercept equation
y = 6x + 68
Answer:
23
Step-by-step explanation:
F=(9/5)c + 32
F=(9/5)(-5) + 32
F=(-9) + 32
F=23
Answer:
260 machines for minimum cost.
Step-by-step explanation:
c(x) = 0.3x^2 - 156x + 26.657
Finding the derivative:
c'(x) = 0.6x - 156
0.6x - 156 = 0 for maxm/minm cost.
x = 156 / 0.6
= 260
The second derivative is positive (0.6) so this is a minimum.
