Answer:
d. linear; $25/hour
Step-by-step explanation:
From looking at the graph, we have that renting for 2 hours costs $50, for 4 hours costs $100, for 6 hours costs $150, and for 8 hours costs $200. To find out whether the quantities described in the table are linear, we have to see if there is a constant rate of change of price.
For hour 2 to hour 4, we can see that the price increases by $50. This is the same for hour 4 to hour 6 and hour 6 to hour 8. For every 2 hour time interval, the price increases by $50. Therefore, there is a constant rate of change and the quantities described in the table are linear.
Now we have to find the constant rate of change per hour. We know that the price increases by $50 every 2 hours, so, by dividing both the hours and price increase by 2, the price increases by $25 per hour. So the constant rate of change is $25/hour.
Linear. $25/hour

Answer: the perimeter of the rectangle is 38 cm
Step-by-step explanation:
Let h represent the base of the rectangle.
The base of a rectangle is 6 cm longer than its height. This means that the base of the rectangle is
h + 6
The area of the rectangle is 91 cm²
This means that
h(h + 6) = 91
h² + 6h - 91 = 0
h² + 13h - 7h - 91 = 0
h(h + 13) - 7(h + 13) = 0
h - 7 = 0 or h + 13 = 0
h = 7 or h = - 13
Since the height cannot be negative, it means that h = 7 cm
The base is
h + 6 = 7 + 6
base = 13
Perimeter = 2( base + height)
Perimeter = 2(13 + 6) = 2 × 19
Perimeter = 38 cm
