Answer: $12.5
Step-by-step explanation:
The $100 Is 100 percent meaning that one percent is $1. Take that and multiply it by 12.5 and get $12.5
Answer:
The third choice: g(x) = (x + 3)²
Step-by-step explanation:
When translating left, you add the units shifted to x, so instead of x, we have (x + 3)
Answer:
99 units.
Step-by-step explanation:
The cost function for manufacturing <em>x</em> units of a certain product is:

We want to find the number of units manufactured at a cost of $8350. Therefore:

Subtract 8350 from both sides:

This equation can be a bit difficult to factor, if even possible, so we can use the quadratic formula:

In this case, a = 1, b = -15, and c = -8316. Thus:

Simplify:

Evaluate:

Therefore, our solutions are:

We cannot produce negative items, so we can ignore the second answer.
Therefore, for a cost of $8350, 99 items are being produced.

When reflecting across the y-axis, the y in (x, y) stays the same but the x's sign is changed to the opposite.
direct proportion y=kx , k is constant and k does not equal to 0.
17.5=k(21)
k=5/6
when x =39
y=5/6 ×39
y=32.5
