Answer:
The meeting room must be rented for less than 7 hours
Step-by-step explanation:
There are 2 types of costs in this situation
Fixed cost = $ 33
Variable cost = 9.70t
Where t is the number of hours.
The total cost C will be the sum of the fixed cost and the variable cost
We want C to be less than 100.90
So:
We solve for t and obtain.
Answer:
b
Step-by-step explanation:
In general
Given
y = f(x) then y = f(Cx) is a horizontal stretch/ compression in the x- direction
• If C > 1 then compression
• If 0 < C < 1 then stretch
Consider corresponding points on the 2 graphs
(2, 2 ) → (4, 2 )
(4, - 2 ) → (8, - 2 )
Indicating a stretch in the x- direction.
y = f( ) with C =
, that is 0 < C < 1
stretches the graph in the x- direction by a factor of 2
Thus
y = f( ) → b
