Answer:
V = $3.50t + $90.5....
Step-by-step explanation:
V(t) is a function of t that expresses the value in year 2000+t.
We know that the increase is $3.50 times t.
So,
V(t) = $3.50t + c
where c is the constant.
V(15) = $3.50 (15) + c = $143 [t=15 as mentioned in the question]
and therefore
c = $143 - $3.50 (15)
c= $143 - $52.50
c= $90.5
Now we got the value of c. We can write the equation as
V = $3.50t + $90.5....
Answer:
The equation listed is linear because 2x is a constant, meaning that it continuously moves in a straight line in one set direction.

Answer:
A
Step-by-step explanation:
The Y-intercept is -3.
The gradient is -3/4 since it goes down 3 every 4 tiles.
207$ - 15$ = 192$
192$ : 8 = 24$
Answer: Each book costed 24$.
