A retailer who sells backpacks estimates that by selling them for x dollars each, she will be able to sell 100−x backpacks each
zvonat [6]

Answer:

x = 50

R = $2500

Step-by-step explanation:

Given in the question a quadratic equation,

−x² + 100x

To find the selling price, x, which will give highest revenue, y, we will find maximum value of parabola curve −x² + 100x

The value of -b/2a tells you the value x of the vertex of the function

−x² + 100x

here a = -1

        b = 100

Selling price = -(100)/2(-1)

                    =   50

 

R = −(50)² + 100(50)

  = 2500

WHATS THE ANGLE MEASUREMENTS ?? & TELL HOW YOU GOT IT !!
Dafna1 [17]

Answer:

...

Step-by-step explanation:

7x - 2 +5x - 10 +4x = 180

16x - 12 = 180

16x = 168

x = 10.5

now plug it in

7(10.5) - 2 = 71.5°

4(10.5) = 42°

5(10.5) -10 = 42.5°

The variable Z is inversely proportional to X. When X is 6, Z has the value 2.
Vera_Pavlovna [14]
Inverse proportion is of the form:

y=k/x, in this case the variables are

z=k/x, and we are given the point (6,2) so we can solve for k

2=k/6

12=k, so our equation is:

z=12/x, so when x=13

z=12/13
