Answer:
(Some textbooks describe a proportional relationship by saying that " y varies proportionally with x " or that " y is directly proportional to x .") ... This means that as x increases, y increases and as x decreases, y decreases-and that the ratio between them always stays the same.

Answer:

Step-by-step explanation:
The range is set of all y-values. The range starts from minimum value to maximum value.
We don't have minimum value (approaching negative infinity.)
We have maximum value at x ≈ 2 equal 6.
Therefore the answer is
-inf <= y <= 6. But we don't usually write that. Instead, we cut out -inf and we get —

Answer:
Song =$1.50 Album =$12.99
Step-by-step explanation:
Lets assume Individual songs = x
albums=y
6x + y = 21.99-------- y= 21.99- 6x
4x + 3y= 44.97
Replace y in the second equation
4x+ 3(21.99-6x) = 44.97
4x +65.97- 18x = 44.97
14x= 21
x = 1.50
y= 21.99- (6*1.50)
= 12.99

Answer:
D
Step-by-step explanation:
let y = f(x), that is
y = 
Rearrange making x the subject
Multiply both sides by 5
5y = 2x - 3 ( add 3 to both sides )
5y + 3 = 2x (divide both sides by 2 ) , then
x = 
Change y back into term of x, hence
(x) =
