20& 10/35 - 26/35
19& 16/35 simplified to it's fullest.
Answer:
The correct answer is

Explanation:
We are given the points:
(0, 4)
(1, 5)
(2, 6)
(3, 7)
We can see that for each unit that x-coordinate grows, the y-coordinate also grows one.
This means that the slope of the line is m = 1
The first point given, tell us the y-intercept: (0, 4)
The slope-intercept form of a line is:

Where m is the slope and b the y-intercept.
For the points given:
m = 1
b = 4
Thus:
Answer: i) f(-9)= 66
ii)
.
iii) 
Step-by-step explanation:
The given function :
.
i) For f(-9) , the independent variable is x= -9.
Put x= -9 in given function , we get


Thus , f(-9)= 66
ii) For f(x+1) , the independent variable is x= x+1.
Replace x by x+1 in given function , we get
.
![[\because\ (a+b)^2=(a^2+b^2+2ab)]](https://tex.z-dn.net/?f=%5B%5Cbecause%5C%20%28a%2Bb%29%5E2%3D%28a%5E2%2Bb%5E2%2B2ab%29%5D)


Thus ,
.
iii)For f(-x) , the independent variable is x=-x.
Replace x by -x in given function , we get
.
[∵ (+)(-)=(-)]
Thus , 
Answer:
Step-by-step explanation:
The answer is 65. You just add the number of computer towers that fall into that category. So your sum would look like this:
Divisor: 5+ 12 + 21 + 15 + 12 = 65
The question does not ask you to do any more than figure out what you will be dividing by. Thank goodness it does not ask what you will be dividing into which is a whole lot more complicated problem.
