insert the y value in the equation,
Answer:
76; 20
Step-by-step explanation:
s = small room = 2
l = large room = 4
14s + 12l = 28 + 48 = 76
as I said before s = 2 and l = 4
s*s + l*l = 2*2 + 4*4 = 4 + 16 = 20
The answer is-B (x-9) (x-9)
Answer: The answer is f(x) = -7x + 7.
Step-by-step explanation: We are give a relation as follows :

From here, we need to find the expression for f(x).
Here, we will be using the following properties of exponents :

We have

Thus, the required expression is f(x) = -7x + 7.
Answer:
If any horizontal line intersects the graph of f more than once, then f does not have an inverse. If no horizontal line intersects the graph of f more than once, then f does have an inverse. The property of having an inverse is very important in mathematics, and it has a name.
