Answer:
f(-1)=8
Step-by-step explanation:
Just plug in x=-1 into the function:
f(x)=6-2x
y=6-2(-1)
y=6+2
y=8
So f(-1)=8
Nice... you might have put the wrong picture lol
Answer:
6x-21
Step-by-step explanation:
Answer: R(x) = 0.25x + 500
Flat fee is computed by:
The sales price of each tile is 0.25 and the customer only bought 10,000 tiles.
So, $0.25 x 10,000 = $2500
So the total sales price per tile sold was $2,500.
The buyer paid $3,000, so the flat fee was included there.
So, $3,000 - $2,500 = $500
So the flat fee was $500.

The revenue function is the total income from producing the units. And it has a equation of: R(x) = price per unit x number of units sold plus any fee that is included
So the function describing the revenue of the tile from this sale is:
R(x) = 0.25x + 500
