Answer:
Step-by-step explanation:
If we are to write an equation of the form 
, then the function is linear; therefore, it has a constant slope 
.
The slope of the function is given by
thus we have
Now we find 
from the fact that the first month of service costs $72.99, which gives us 
, or
Substituting the values of and , we get our equation in the final form:
The answer is 1,670 because you have to multiply 35*8 which equals 280 and subtract it from 1950, and you get 1,670.
Answer:
The volume is 140
Step-by-step explanation:
V = l × w × h
V = 7 × 5 × 4
V = 140
Answer:
- NOT a function
- domain: [-2, 2]
- range: [-4, 4]
Step-by-step explanation:
A vertical line intersects the graph twice, so the relation is not a function. It is only allowed to intersect once if the relation is a function.
The domain is the horizontal extent, which is from -2 to +2.
The range is the vertical extent, which is -4 to +4.
