Answer:

-49/8

Convert both numbers to improper fractions:

-7/3 times 21/8.                                            (-7)(21)

Now multiply these together, obtaining ---------------

Helppppppp math !!!!!!!!!!

We conclude that the profit if the company produces 10 units is 1,040 dollars.

<h3></h3><h3>How to find the profit?</h3>

The profit is defined as the difference between the revenue and the costs.

In this case, we know that the revenue and costs are defined by:

R(x) = 200x - 5x^2

C(x) = 360 + 6x

Then the profit equation is:

P(x) = R(x) - C(x).

P(x) = 200x - 5x^2 - (360 + 6x)

P(x) = -5x^2 + 194x - 360

Now we want to find the profit when x = 10, then we will get:

p(10) = -5*10^2 + 194*10 - 360 = 1,040

We conclude that the profit if the company produces 10 units is 1,040 dollars.

Solve the inequality.<br><br><br> n + 9 &lt; −3
storchak [24]
When solving this inequality, you would do the inverse to the other side.

Subtraction is the inverse of addition.

So,

n + 9 (-9) <-3 (-9)

n<-12

When you subtract two negative numbers, you continue to the left of the number line.

I hope this helps!
