I'd use synthetic div. here, with 2 as my divisor:
________________
2 / 1 -11 18
2 -18
----------------------------
1 -9 0
Note that the coefficients of the missing factor are given here and are 1 and -9. Thus, (x-9) is the missing factor.
Answer: 115, 2645
(x= 115, y= 2645)
Step-by-step explanation:
There are two methods to this, which is using the graph with each x and y value, or substituting in values.
I would suggest looking at the graph first and then substituting values so you know the equation is being satisfied by the ordered pair.
In this case, one way to check it could look like this (substituting y value):
y = 23x
2645 = 23x
x = 2645÷23
x = 115
29.99 + 35.00 + 3.25 + 3.25 = 71.49
125.00 - 71.49 = 53.51
53.51 ÷ 22.50 = 2.4 = 2

Answer:
12.5
Step-by-step explanation:
f of x just means y, so you're just finding y when x = 1/2
