Answer:

No solution

Step-by-step explanation:

Simplify the equation to solve for x.

-9(x+6)=-9x+108  Distribute

-9x-54=-9x+108 Combine like terms

+9x       +9x

0-54=108 Combine like terms

 +54  +54

0=162 No solution

© Given that R= 9x + 8y
Phantasy [73]

Answer:

-19/9

Step-by-step explanation:

First, you would plug in the numbers for y and r. Therefore, your equation should now be 5 = 9x + 24. Now you would put like terms on the same side. It now then look like -19 = 9x. You divide by 9 to get the x by itself. The answer should be x = -19/9.

1. Assuming that the company sells all that it produces, what is the profit function?
nalin [4]

The  profit function is R(x) = -0.5 (x - 50²) + 1150

  • The domain of P(x)  is:  0 ≤ x ≤ 150
  • Profit when producing 50 items = 1150
  • Profit when producing 60 items =  1100
<h3> What is the profit function about?</h3>

Note that:

1. Profit  = Revenue - cost

P (x) =  0.5 ( x - 90²) + 4050 - 40x - 100  

= 0.5 ( x² - 180 + 8100 + 4050 - 40x - 100  

=0.5 x² - 50x - 100  

=0.5( x² - 100x) - 100  

=  -0.5 (x - 50²) + 1150

2.  Since the minimum unit is 50.

Then   x ≤ 150

X = describe the item so it need to be a negative number

  • x ≥ 0

Hence the domain of P(x)  is:  0 ≤ x ≤ 150

3. Assume x = 50 , 60

R(50) = 1150 , R (60 ) = -0.5 (60-50)² + 1150 = 1100

4. R (x) = -0.5 (x-50)² + 1150  then 50 more unit is removed hence, Profit when producing 60 items =  1100

Therefore, The  profit function is R(x) = -0.5 (x - 50²) + 1150

  • The domain of P(x)  is:  0 ≤ x ≤ 150
  • Profit when producing 50 items = 1150
  • Profit when producing 60 items =  1100

What is the percentage of 28,24,29,18,13,43,38,14,49,32 with a fuel efficiency less than 32mpg
Anni [7]

The percentage of these cars with a fuel efficiency less than 32 mpg is; 90%

<h3>How to Find the percentage?</h3>

We are can the efficiencies of 10 cars in mpg.

Now, among the 10 cars, the number of cars that have an mpg less than 32 mpg are 9 cars.

Thus, percentage of these cars with a fuel efficiency less than 32 mpg is;

Percentage = 9/10 * 100%

Percentage = 90%

Complete question is;

Here are the fuel efficiencies (in mpg) of 10 new cars; 28, 24, 29, 18, 13, 43, 38, 14, 49, 32. What is the percentage of these cars with a fuel efficiency less than 32 mpg?
