Step-by-step explanation:
-4x + 9y = -22
-9x -9y = 126
-13x = 104
x = -8
8 +`y = 14
y = 6
(-8,6)
Answer:
(2c³ -20c² -10c) -(c² -40c +100)
Step-by-step explanation:
<u>Profit</u>
For a problem involving cost, revenue, and profit, you are expected to know that <em>profit is the difference between revenue and cost</em>. That is, if it costs you $2 to make a necklace you sell for $10, your profit is $10 -2 = $8.
<u>Problem</u>
The problem gives you polynomial expressions for revenue and cost, and asks you to combine them to make an expression for profit. In this first part, we simply show <em>how</em> we will combine them. (We presume a later part of the question will ask you to simplify the result.)
profit = revenue - cost
Substituting the given expressions, we have ...
profit = (2c³ -20c² -10c) -(c² -40c +100) . . . . . matches last choice
Hai , you can use Pythagoras Theorem to find the length which is hypotenuse.
It will be 7^2 + 3^2 = 58
square root 58 and you will get 7.62
Hope this helps and i am sorry if my answer was wrong .
A manufacturing company has the following fixed monthly costs and unit variable costs:
Rent = $2,200
Utilities = $375
Variable costs for materials and assembly = $13.25/unit
Monthly labor = $750
Given is the product is sold at $24.99 per unit
Let the number of units sold be x
Adding total cost = 
Equation becomes:
x= 283.21
So, rounding it to nearest whole number we get, 283 units.
