A pizza company charges $8 for a large pizza and a $5 delivery charge. Write an equation that gives the

1 answer:

3 0

8p +5 = $29
The above is the equation

If you want to know how many pizza were ordered then you subtract 5 from each side of the equal sign then you would have 8p=24 then divide by 8 on both sides of equal sign . p= 3 ; so 3 pizzas were order plus a charge of $5 for delivery.

-4x + 2(5x - 6)= -3x - 39 solve for x

Veseljchak [2.6K]

Answer:

x = -3

Step-by-step explanation:

-4x + 2(5x - 6) = -3x - 39

-4x + 10x - 12 = -3x - 39

-4x + 10x = 6x

6x - 12 = -3x - 39

+3x _ +3x

9x - 12 = -39

+ 12 +12

$\frac{9x}{9} = \frac{-27}{9}$

x = -3

-30 = -30

The revenue function for a bicycle shop is given by R(x)=x⋅p(x) dollars where x is the number of units sold and p(x)=800−0.5x is

Semenov [28]

Answer:

The maximum revenue is $320,000

Step-by-step explanation:

To find the maximum of a function f, the procedure is as follows:

Find the first derivative of f.
Equate the derivative to 0. Solve the resulting equation to get the critical points.
Try all the critical points in the original function and select the one that maximizes it.

The revenue function for a bicycle shop is

R(x)=xp(x), where p(x)=800-0.5x. Substituting:

$R(x)=x(800-0.5x)=800x-0.5x^2$

Find the first derivative of R:

R'(x)=800-x

Equate to 0:

800-x=0

Solve:

x=800

There is only one critical point. Substitute it into the revenue function:

$R(800)=800(800)-0.5(800)^2=320,000$

The maximum revenue is $320,000
