Symbolab has a calculator that solves problems like that and works it out for you, to help understand it better :)
Hi Scotti
0>3x-3-6
0>3x-9
Now flip
3x-9<0
We need to add 9 to both sides
3x-9+9<0+9
3x<9
Divide both sides by 3 so we can find the value for x
3x/3<9/3
x<3
I hope that's help :)
You know if something is a function or not because of the X will not be repeated. If it is, then it's not a function.
A. 0 and 2 are repeated in X
B. Nothing is repeated for X
C. 2 and 3 are repeated for X
D. 2 and 3 are repeated for X
B is your answer
So our original equations would be..
(a) perimeter in terms of y
(b) area in terms of y
*I'm actually not sure about b.. sorry*
(c) if perimeter = 28, find length
Step-by-step explanation:
i hope it's helpful......
