Answer:
C
Step-by-step explanation:
It curves so it automatically means it isn't any of the answers that say it is.
Numbers with variable powers are NEVER linear, so it is C.
Answer:
number 1 + number 2 + number 3 = 15
Number 1 = x + 12
Number 2 = x - 12
Number 3 = x
(x + 12) + (x - 12) + x = 15
x + 12 + x - 12 + x = 15
x + x + x +12 -12 = 15
3x = 15
x = 15/3 = 5
Check:
Number 1 = 17
Number 2 = 5 -12 = -7
Number = 5
number 1 + number 2 + number 3 = 15
17 + (-7) + 5 = 15
10 + 5 = 15
15 = 15
Answer is 5
Step-by-step explanation:
A
This is one of those questions that is hard to explain, because I don't know what you know. I'll start with the most obvious reason I know. At x = -1 the top and bottom of the function is 0/0. zero/zero can give indeterminate results and you must look for other ways of explaining what is going on. Here's another thought which is less reliable.
The fraction factors.
(x + 1)*(x - 1)
============
(x + 1)
The two common factors cancel and you are left with f(x) = x - 1
If you have a graphing calculation you can put this in as y = x - 1 and you see that it is a straight line.
Question B is much nicer
when you put x = 1 into the fraction, you get 0 /2 which gives you 0. That's much easier to handle because the answer is 0.
you are still graphing y = x - 1, but this time the graph is much more well behaved.
Answer:
if you want in terms of π, then 3π
if you want it without π, then 9.42
Step-by-step explanation:
plug into formula
3= diameter
c=πd
c=π*3
3π or
π=3.14
so 3.14*3, which is 9.42
Answer:
15/4
Step-by-step explanation:
