The graph is stretch/shrunk by a factor of a. The Domain is h=
125 and 8 are perfect cubes.
125 = 5^3
8 = 2^3
125 - 8 = 5^3 - 2^3
Answer:
B is 6.
Step-by-step explanation:
We are trying to find a value for
such that:
is true for every
.
So let's choose
:




Divide both sides by -8:



Note: I didn't want to choose y to be 0 because the value of B would disappear from the equation. So you should be able to have chosen any x and y except for y=0 to solve the equation for B.
Check:
So let's check and use foil to multiply out the right hand side.




There was a 2 in front of that multplicapltiation:



This is exactly what we have on the left hand side of your given equation.
First, write a statement to define your unknown variable. This is technically not essential to solving the problem, but many teachers prefer to see it.
Example: Let w = the manatee's weight in pounds.
Next, decide what the variable needs to be multiplied by. 12% is equal to 0.12. Usually when a problem says "of," it wants you to multiply. Therefore, 12% of the body weight equals 0.12w. Since the problem already says that this is how much the manatee eats every day, that is your answer.
y = 0.12w
There's an infinite number of ways we can rewrite 16 3/4, some of them being:
16 3/4
16 6/8
16 12/16
16 24/32
16.75
67/4
335/20
670/40
etc.
I hope it will help you ;)
