website host $32. What was the final selling price of the antique?
A. $68.
B. $600.
C. $680.
D. $1,280.
The final sellingprice of the antique was $680.
The correct answer is option C.
An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the liketerms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Let's assume the final sellingprice of the antique to be x.
According to the given information,
Kyle had to pay the website host $15 plus 2.5% of the final sellingprice.
Now,
The totalamount Kyle had to pay.
= $15 + 0.025x.
It is given that Kyle had to pay $32, so we can set up the equation:
$15 + 0.025x = $32
Subtracting $15 from both sides:
0.025x = $17
Dividing both sides by 0.025:
x = $680
Therefore,
The final sellingprice of the antique was $680.

Therefore, the inverse of f(x)=-8x+4 is (4-x)/8
What is mathematic expression?
A mathematical expression is defined as the collection of the numbersvariables and functions by using signs like addition, subtraction, multiplication, and division.
here, the function given is f(x) = -8x+4
and to find its inverse we replace f(x) = x and x = f(x) and solving for f(x) we get :
f(x) = -8x+4
x = -8f(x) +4
8f(x) = 4-x
f(x) = (4-x)/8
Therefore, the inverse of f(x)=-8x+4 is (4-x)/8

To find the inverse of f(x) = -8x + 4,
1) replace "f(x)" with "Y:" y = -8x + 4
2) interchange x and y: x = -8y + 4
3) solve this result for y: -8y = x - 4, or y = (x - 4)/(-8)
-1
4) replace this "y" with f (x): ":
-1 x - 4
f (x) = - ----------
