Answer: The relation is a function.
Step-by-step explanation: Since there is one value of y for every value of x in (-2,4), (3,7), (0,8), (5,8), and (1,6), this relation is a function.
I hope this helps you out!
Step-by-step explanation:
Let's make the number we're finding to be
. So, it says that it will be divided by 4 and then added by 12 if we want this in algebraic expression it will be
. It's also telling us that that expression is the same thing as our number divided by 3 and subtracted by 5. If we want an expression out of it it well be
. Since they are the same, we have the equation below.

All we have to do now is to find
.

<h3>Answer:</h3>
Our number must be
. I think

Substituting given values into the equation and solving for r:






Answer:

Step-by-step explanation:
The standard form for the equation of a circle is
where r is the radius, and the center is (h, k).
(h, k) = (-1, 2), r = 7
