Step-by-step explanation:
I assume we are simplifying
1) -6k+7k = k
2) 12r-8-12 = 12r-20
3) n-10+9n-3 = 10n-13
4) -4x-10x = -14x
Answer:
4/2
Step-by-step explanation:
x=8
Step-by-step explanation:
move the +2 to the right side so it can be subtracted by the 5 to get 3. after that you square both sides of the equation to get rid of the square root symbol. then move the -7 to the right side and add it with 9. then you'll have 2x=16. then divide both sides by 2 to get x by its self and you are left with x =8
Answer:
Step-by-step explanation:
A linear equation, when graphed, gives a straight line. This looks like you meant y=3x^3 - 3
There are parts of this equation that look like they could be linear, but the graph below shows that the graph does not go straight through -3. The graph therefore is non-linear.
