Answer:
f(8) = 21
Step-by-step explanation:
First, identify the equation of the line using the form: f(x) =mx + c, where m is the gradient and c is the y-intercept (the constant)
To find gradient, use the rise over run formula: (y2 - y1)/(x2 - x1)
You can use any points but I am going to use (2,3) and (3,6)
(6 - 3)/(3 - 2)
3/1 = 3 (gradient of the graph is 3)
Hence the equation is simplified to: f(x) = 3x + c
Now we need to find the value for c. To do this, you sub in any point, and I am going to use (3,6)
6 = 3*(3) + c (rearrange it to make c on its own)
6 - 9 = c
c = -3
Hence the equation of the line is: f(x) = 3x - 3
So we are trying to figure out what f(8) equals. That means we sub in the value 8 where x is.
3*(8) - 3 = 21
f(8) = 21

Answer:
The function that represents the cost in cents of ‘d' dozen gumballs is y = 10d .
Step-by-step explanation:
As given
If 30 gumballs can be purchased for 3 dollars .
i.e
30 gumballs = $3
Now find out the cost of one gumballs .
As 1 dollar = 100 cents
1 gumballs = 10 cents
Thus the cost of one gumball is 10 cents .
As d = dozen gumballs.
Let us assume that the cost for ‘d' dozen gumballs = y
Than the function becomes
y = 10d
Therefore the function that represents the cost in cents of ‘d' dozen gumballs is y = 10d .
Answer:
90 divided by 10
Step-by-step explanation:
This is the answer because when you divide the 90 and the amount of students in each van(10) you would get the equation needed to see how many students are in each van.
