Which relation describes a function?
Kisachek [45]

Answer:

{(-2, -3), (-3, -2), (2,3), (3, 2)}

Step-by-step explanation:

A function is a set of ordered pairs in which <u>no two pairs have the same first number</u>.

In other words, an <em>x</em> cannot be paired with two <em>y</em>'s.

A function takes an <em>x</em> and pairs it with one and only one <em>y</em>.

{(0,0), (0, 2), (2.0), (2, 2)} is not a function because it pairs 0 with both 0 and 2.

{(2,-1), (2, 1), (3,-1), (3, 1)} is not a function because it pairs 2 with both -1 and 1.

{(2, 2), (2, 3), (3, 2), (3, 3)} is not a function because it pairs 2 with both 2 and 3.

Solve –3 + c = –8.<br> A. -5 B. 11 C. 5 D.-11
sergey [27]

Answer:

The answer is A. -5

Step-by-step explanation:

Write out the equation:

-3 + c = -8           Add 3 on both sides to isolate the varible on one side

       c =  -5         -8 plus 3 is -5

You must isolate the variable in order to solve equations with variables.

Isolating variable is basically when you divide, multiply, add, or subtract to put a variable on <u><em>ONLY </em></u>one side of the equation.

Neil has 3 partially full cans of white paint. They cantain 1/3 gallon, 1/5 gallon, and 1/2 gallon of paint. About how much pain
Marianna [84]

Answer:

1  1/30 gallons, or 31/30 gallons of paint

Step-by-step explanation:

Before these fractions can be added together they have to have a common denominator.  The Least Common Multiple of 2, 3, and 5 is 30, so

1/3 = 10/30   1/5 = 6/30   1/2 = 15/30

10/30 + 6/30 + 15/30 = 31/30, or 1  1/30
