Put the value of x = -1 to the equation of a function f(x):

Step-by-step explanation:
You multiply the two other sides by itself like 12x12=144 and do that for all the sides that you know then you add up all of the numbers you got from adding like 144 plus 64 equals 208 and then 208 is the hypotenuse.
SOLUTION
Given the question in the question tab, the following are the solution steps to get the rental cost for each movie and each video game.
Step 1: Write the representation for the two rentals
Let m represents movies
Let v represent video games
Step 2: Write the statements in form of a mathematical equation

Step 3: Solve the equations above simultaneously using elimination method to get the values of m and v

Rental cost for each movies is $3.25
Rental cost for each video games $5.50
3/4 X 10= $7.50
Because 3/4 is 75%, 10 is the original price. And 75% times 10 is 7.50<span />
