Hello from MrBillDoesMath!
Answer:
Choice B ( (x+6)/5) )
Discussion:
y = f(x) = 5x - 6
To solve for the inverse of f, replace "y" by "x" and "x" by "y" in the original equation. That is, solve for "y" in
x = 5y -6 => add 6 to both sides
x + 6 = 5y => divide both sides by 5
y = (x+6)/5
"y" above is the inverse, which is Choice B
Thank you,
MrB
In order to calculate the Circumference, You can Use the formula:
C = 2πr
C = πd
They are valid one's, depends, on the given value, either diameter or radius
Hope this helps!
You have to perform operations inside parenthesis first:
And finally,
Answer:
8
Step-by-step explanation:
-4+3=-1
|-4+3|=1
|-4+3|•8=8
(|) the vertical line represent absolute value if it is a negative number inside the vertical lines it gives a positive number
Examples:
|-1|=1
|-4|=4
Hope you understand
25%
Because 25% (1/4) of four is 1/1 or simply just 1. Now if we subtract 1 from 4 we get 3. This is the same as subtracting 25% from four.
To find the percentage of a number thorn the percentage into a fraction and multiply them together. e.g. 1/4 * 4 = 4/4 = 1
