Answer:
A
Step-by-step explanation:
- (x + 3) > x - 3 ( multiply both sides by 2 to clear the fraction )
- (x + 3) > 2x - 6 ← distribute parenthesis on left side by - 1
- x - 3 > 2x - 6 ( subtract 2x from both sides )
- 3x - 3 > - 6 ( add 3 to both sides )
- 3x > - 3
divide both sides by - 3, reversing the symbol as a result of dividing by a negative quantity
x < 1
Answer:
6 yards long
Step-by-step explanation:
1/3 yards wide = 2 yards long
Let x = length of the other rug
1 yard wide = x yards long
1/3 : 2 = 1 : x
1/3 ÷ 2 = 1 ÷ x
1/3 × 1/2 = 1 / x
1/6 = 1/ x
Cross product
1*x = 6*1
x= 6 yards
Therefore, the length of the new rug with 1 yard wide is 6 yards long
The first thing to do is to find the ratio of wide to long of the two rugs by representing the long of the second rug with x
It is the simplest method to solve the question
Given:
Fixed cost = b = $ 42,500
Production cost (Variable cost) /unit = m = $ 6/ unit
Let 'x' represent the number of unit, therefore the variable cost will be
a) The cost function will be the sum of the fixed cost and the variable cost.
b) The revenue function is the amount the product is sold per unit.
Recall: 'x' represents the number of units.
Therefore,
Hence, the revenue function R(x) is
c) The profit function is the difference between the revenue function and the cost function.
Hence, the profit function is
d) Let us compute the profit (loss) values when the units are 6000 and 11000
Using the profit function
Therefore,
Hence,
