Answer:
f(9) = 72
Step-by-step explanation:
This is a piecewise function. You have to establish what part to plug in your x value based on the designations given in the function. In this case, x=9.
9>6, so we would follow the bottom designation! When writing the function, turn every "x" into a 9.
f(x) = 8x
f(9) = 8(9)
f(9) = 72
Hope this helps you out :)!
55 degrees. If you add the other three angles together you get 305. Considering that a circle is 360 degrees, you would subtract those two and get 55.

A and E
Step-by-step explanation:
Answer:
500
Step-by-step explanation:
Let x be the original price
Take the first discount
x - 18 percent
x - .18x = new price
x( 1-.18)
x ( .82) = new price
Now we take a 20 percent discount
This is on the discounted price, use .82x
.82x - 20 percent= 2nd discounted price
.82x - .20(.82x)
.82x -.164x
.656x= 2nd discounted price
.656x = 328
Divide each side by.656
.656x/.656 = 328/.656
x =500
The original price was 500
