ElenaW [278]

Answer

40%

Explanation

A parentage value is a value that has been compared to 100.

Percentage = (change in the value)/(the original value) × 100%

= (35-25)/25 × 100%

= 10/25 × 100%

= 40%

You sell apple cider for a fundraiser. For each gallon of cider you sell, the company that makes the cider receives $x$ dollars,

pav-90 [236]

Answer: You receive 14x+45 dollars for each gallon of cider that you sell.

Step-by-step explanation:

Given: For selling each gallon of cider, the company receives x dollars.

You receive = Remaining amount

i.e. You receive $(Selling price - x)

By selling 15 gallons in 15x+45 dollars, you have received (15x+45)-x dollars

i.e. You received 15x+45-x dollars

i.e. You received 14x+45 dollars.

Hence, you receive 14x+45 dollars for each gallon of cider that you sell.

How can you use a point on the graph of f –1(x) = 9x to determine a point on the graph of f(x) = log9x?

Anastasy [175]

Whenever you can invert a function, you have that the graphs of $f(x)$ and its inverse $f^{-1}(x)$ are reflected with respect to the line $y=x$

So, given any point on the graph of $f^{-1}(x)$ , you can simply swap its coordinates to get the correspondent point on the original function $f(x)$

As an example, all exponential functions pass through the point $(0,1)$ , while all the logarithmic functions pass through the point $(1,0)$
