The answer to the question
Answer:
All real numbers
Step-by-step explanation:
Start by distributing -2 inside the parentheses.
Combine like terms on the right side of the equation.
Subtract 8 from both sides of the equation.
Divide both sides by -2 to isolate y.
This is a true statement, so there are infinite solutions.
Answer:
Ratios are proportional when the numbers in the ratio are multiply or divide by the same number. Ex. 3:5 = 6:10 = 12:20 = 9:15 (cross multiply the fractions and the results are the same 3/5 = 6/10)

<h2>A), D) and E)</h2>
Step-by-step explanation:
<em>A function is a relation for which each value from the set the first components of the ordered pairs is associated with exactly one value from the set of second components of the ordered pair.</em>
{(-5, 3), (4, 9), (3, -2), (0, 6)}
A) (-3, -2) YES
B) (4 0) NOT <em>because we have the pair (</em><em>4</em><em>, 9)</em>
C) (0, -1) NOT <em>because we have the pair (</em><em>0</em><em>, 6)</em>
D) (1, 6) YES
E) (2, 3) YES
F) (-5, 9) NOT <em>because we have the pair (</em><em>-5</em><em>, 3)</em>
