Answer:
9 tapes
Step-by-step explanation:
First, subtract the handling charge from his $78.
78 - 3.50 = 74.5
So, Brian has $74.50 to purchase tapes. Each tape costs $7.50, so let's find out how many he can purchase.
74.50 / 7.50 = 9.933 (approximately)
Since Brian can't buy 0.933 of a tape, he will only be able to buy 9 tapes.
Answer: They are inverses of each other.
Explanation:
f(x) = -x+5
f(g(x)) = -(g(x)) + 5
f(g(x)) = -(-x+5) + 5
f(g(x)) = x - 5 + 5
f(g(x)) = x
The steps to show that g(f(x)) = x are identical to what is shown above. This is because both f(x) and g(x) are the same.
Since f(g(x)) = x and g(f(x)) = x are true, this means the functions are inverses of each other.
Answer:
3.75
Step-by-step explanation:
We have to find the slope of a straight line through points (-5,-10) and (-1,5).
Now. we know the slope of a straight line through the points (
) and (
) is given by ![[\frac{y_{2} - y_{1} }{x_{2} - x_{1}} ]](https://tex.z-dn.net/?f=%5B%5Cfrac%7By_%7B2%7D%20-%20y_%7B1%7D%20%7D%7Bx_%7B2%7D%20-%20x_%7B1%7D%7D%20%5D)
.
So, in our case () ≡ (-5,-10) and () ≡ (-1,5).
Therefore, the slope of the line is
