Answer:
2/3
Step-by-step explanation:
3(y - 1) = 2x + 2
3y - 3 = 2x + 2
3y = 2x + 5
3y/3 = 2x/3 + 5/3
y = 2/3x + 5/3
Does that help?
Answer:
No
Reasoning:
If something is a perfect cube, it is able to be put under a cube root (
) and will result in an integer (a non-decimal number > 0, basically).
So let's calculate
, and see if the result is an integer.
= 3.634.......
As you can see, the result is not an integer, therefore 48 is not a perfect cube.
5 (7) - 3 (-8)
35 - -24
Because two negatives equal a positive the subtraction sign will change into an addition sign.
35+24
So your answer will be 59.
Hope this helped :)
