Answer:
12
Step-by-step explanation:
3√1000 = 10
because 10 • 10 • 10 = 1000
3√8 = 2
because 2 • 2 • 2 = 8
10+2 = 12
It's not plus or minus because it's a cube root rather than a square root.
Answer:
This is impossible.

The answers are following
sol1 y = x-1
sol2 y= x+ 7
sol4 y = x+4
Step-by-step explanation:
Solution 1
Here we are going put the point in the given equation ( given in the options)
If the each point satisfies any equation, that will be the relationship between x and y.
Given points are (-3,-4) , (2,1) , (5,4)
Let us take the option C as y = x -1
-4 = -3-1
1 = 2-1
4=5-1
Putting each value in the given equation we get LHS and RHS are same for all points. so, C is the answer.
Similarly, option B is the answer of Solution 2
Each point satisfies the equation y = x +7
Solution 4
y = x +4
