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.
D because if you do a rate problem you do 50 times what equals 100 so times two then you do 32 times two

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
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

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?
