Solving for c:
Start with
add 1500+2w to both sides:
Divide both sides by w:
Prize to break even:
If they break even, the profit is zero, and since we know that w=800, the cost is
Answer:
- reflection over the x-axis
- translate right 2 units
- translate down 3 units
Step-by-step explanation:
Horizontal translation of the graph of a function is accomplished by replacing x with (x-h) for translation h units to the right. Vertical translation of the graph is accomplished by adding the amount of translation to the function value: f(x)+k translates the graph k units upward.
Reflection of a function over the x-axis is accomplished by changing the sign of every function value: -f(x).
<h3>Application</h3>
We observe that f(x) has been transformed by ...
- multiplying by -1 to get -f(x)
- replacing x with (x -2) to get -f(x -2)
- adding -3 to the function value to get -f(x -2) -3
The effect of these transformations is (correspondingly) ...
- reflection over the x-axis
- translate right 2 units
- translate down 3 units

The attached graph shows a function f(x) (red) and the transformed function (blue).
Step-by-step explanation:
Let the number be x,
Now,
The difference of a number and 3 is equal to the quotient of 10 and 5.
- (x-3)=(10/5)
- x-3=2
- x=2+3
- x=5
Answer:
{x,y}={8,5}
Step-by-step explanation:
12x + 12y = 156 4x + 6y = 62
