Answer:
5 miles
Step-by-step explanation:
If there is 2 people and it costs 12 dollars you will first subtract 2 dolars for each person leaving you with 10 dollars. After that you will divide 10 by 2 for the miles because each mile costs 2 bucks. that will get you to 5 miles
Slope: M = rise/run = y2 - y1/x2 - x1
Point slope: y-y₁=m(x-x₁)
Slope-intercept: y = mx+b
Answer:
17) MC(x) = 35 − 12/x²
18) R(x) = -0.05x² + 80x
Step-by-step explanation:
17) The marginal average cost function (MC) is the derivative of the average cost function (AC).
AC(x) = C(x) / x
MC(x) = d/dx AC(x)
First, find the average cost function:
AC(x) = C(x) / x
AC(x) = (5x + 3)(7x + 4) / x
AC(x) = (35x² + 41x + 12) / x
AC(x) = 35x + 41 + 12/x
Now find the marginal average cost function:
MC(x) = d/dx AC(x)
MC(x) = 35 − 12/x²
18) x is the demand, and p(x) is the price at that demand. Assuming the equation is linear, let's use the points to find the slope:
m = (40 − 50) / (800 − 600)
m = -0.05
Use point-slope form to find the equation of the line:
p(x) − 50 = -0.05 (x − 600)
p(x) − 50 = -0.05x + 30
p(x) = -0.05x + 80
The revenue is the product of price and demand:
R(x) = x p(x)
R(x) = x (-0.05x + 80)
R(x) = -0.05x² + 80x
1) Y intercept is -5. x is about1.25
2) Y intercept is +2. X is -2
