12. On addition, you can just combine like terms.
2v^3+(-v^3)=v^3
-v+v cancels each other out
8+(-3)=5
So you have v^3+5
14 On subtraction, you have to remember to distribute the negative sign so after you do that you have:
4h^3+3h+1+5h^3-6h+2
Then you can combine like terms
4h^3+5h^3=9h^3
3h-6h=-3h
1+2=3
So you end up with:
9h^3-3h+3

Answer:
k = y/x
Step-by-step explanation:
1/5, 2/10, 3/15 . . . all equal to 1/5 which is what the value of k is; 'k' stands for constant of proportionality
Answer:
Step-by-step explanation:
The given functions are:
and
We want to to find
Note that:
We substitute the functions to obtain:
We now substitute x=7, to get:
This implies that
Answer:
x = 6
Step-by-step explanation:
3(x - 4) = 12 - 2(x - 3)
3x - 12 = 12 - 2x + 6
3x - 12 = 18 - 2x
+2x + 2x
5x -12 = 18
+ 12 +12
5x = 30
x = 6
