Total profit is defined as total revenue, R(x), minus total cost, C(x), and is given by the function P(x) = R(x) – C(x). Given R(x) = 58x – 0.4x^2 and C(x) = 5x+15 following
a) P(x)
b) R(90), C(90), and P(90)

If angle 2=3x +1 and angle 3=2x +4what is angle 2

Find an equation of the line perpendicular to the graph of 28x-7y=9 that passes through the point at (4,1)

Sample response: if the graph passes the horizontaline test, then the function is one to one. functions that are one to one have inverses that a therefore, the inverse is a hinction compare your response to the sample response above. what did you include in your explanation? a reference to the horizontal-line test d a statement that the function is one-to-one the conclusion that the inverse is a function done
