Answer:
Step-by-step explanation:
Function 'f' represents the number of miles (y-values) covered by the helicopter in 'x' (x-values) minutes.
f(x) = 40 - 2x
For x = 0,
f(x) = 40 miles
For f(x) = 0,
0 = 40 - 2x
x = 20 minutes
This shows that helicopter traveled 40 miles in 20 minutes.
Similarly, given graph shows distance covered by the jet on y-axis and duration of flight on x-axis.
For x = 0,
f(x) = 500 miles
For f(x) = 0,
x = 100 minutes
Commercial jet traveled 500 miles in 100 minutes.
Answer:
281
Step-by-step explanation:
8 + 7(42–3) =
= 8 + 7(39)
= 8 + 273
= 281

Answer:
a) the possible values of y are all real numbers from 0 to 150.
b) y is a continous variable.
Step-by-step explanation:
If the maximum depth of the lake is 150 feet, in any point selected on the surface, the depth will be between 0 feet (takes this value of depth only at the shore) and 150 feet.
The depth is a physical measure that can be represented as a continous variable.
In that case, the possible values of y are all real numbers from 0 to 150.
