You can always find a percent by setting up a fraction
and then doing the division.
To set up the fraction, the top number is some percent of the bottom number.
If 400 is some percent of 30, then the fraction is
400 / 30 .
Do the division: 400/30 = 13.333...
To turn a number into a percent, move
the decimal point two places that way ===> .
13.333... = 1,333.333 %
400 is (1,333 and 1/3) percent of 30 .
f(x) = 6x
To find the inverse, replace f(x) with Y:
y = 6x
Now switch the variables:
x = 6y
Solve for Y by dividing both sides by 6:
y = x/6
Now replace y with f^-1 (x):
f^-1 (x) = x/6
Answer:
-2/5
Step-by-step explanation:
You can find this by examining how to get from one point to the other. If you're going from a orange point on the left to one on the right you have to go down 2 units and over 5. That means you do -2 on the y axis and +5 on the x axis. So, with rise over run that equals -2/5.
Answer:
Add each side to get perimeter so your total is 38ft
Step-by-step explanation:
<h3>
Answer: x > -8</h3>
Multiply both sides by 2 so that you go from
x/2 > -4
to
x > -8
The inequality sign will not flip since we are not multiplying both sides by a negative number.
If you are curious how to graph the solution, draw out a number line and plot an open unfilled circle at -8. Then shade to the right of the open circle. The open circle says "do not include this value as part of the solution set". The solution set is shaded representing all of the values larger than -8 (which make the original inequality true).
