The answer would be c (w = 12 feet)!
Answer:
when x is:
1; y = 12
2; y = 10
5; y = 4
6; y = 2
Step-by-step explanation:
Substitute each value of x to obtain respective y values
value of x is: 
Step-by-step explanation:
We need to solve the equation f(x)=g(x)
where 
and 
Solving to find f(x)=g(x)
Putting values of f(x) and g(x)

So, value of x is: 
The graph will be a straight line x= -2.58 or x = -31/12

Answer:
f(5)=225 and f(10)=250
Step-by-step explanation:
Answer:
Time taken by A = 16 seconds
Time taken by B = 12 seconds
Step-by-step explanation:
Given:
Two elevator and their respective time to reach certain height.
Here time is function of height.
Time taken by elevator A = 0.8(h)+16
Time taken by elevator B = -0.8(h)+12
We have to find the time taken by the elevator to reach ground level.
Accordingly:
We know that ground level the height will be zero meaning that (h=0).
Plugging the h values in the equation we can find the time taken by both the elevators to reach zero height that is the ground level.

So,
Time taken by elevator A and elevator B to reach the ground is 16 seconds and 12 seconds respectively.
