Answer:
15) a) 8
b) y + 2
c) y - 1
16) True
17) 2n - 1, where n is an integer
18) a) 3p + 4q

Answer:
22
Step-by-step explanation:
The y values increase by 2 every time so 18+2=22
Rate = 2 seats/11 minutes = 2/11 seats/min
Therefore the time required for s seats is

That is,
m = (11s)/2 min
When s = 16, obtain

When s = 19, obtain

Answers:

When s = 16, m = 88 min
When s = 19, m = 104.5 min
Answer:
A function is a relationship between two variables, such that one variable is determined by the other variable.
A function can be represented verbally. For example, the circumference of a square is four times one of its sides.
A function can be represented algebraically. For example, 3x+6 3 x + 6 .

Answer:
-21/4x-1/2
Step-by-step explanation:
-1/2(-3/2x+6x+1)-3x
3/4x-3x-1/2-3x
3/4x-3x-3x-1/2
3/4x-6x-1/2
3/4x-24/4x-1/2
-21/4x-1/2
