Cube has 6 faces/planes :)
Answer: r = 11
Step-by-step explanation:
We know that the point (-2, r) lies on the graph of:
2*x + y = 7.
Then, if we that point is on the graph of the equation, we can replace the values and we will have:
2*(-2) + r = 7
and now we solve this for r-
-4 + r = 7
r = 7 + 4 = 11
r = 11
Answer:
1/2 rational exponent represents a square root.
Therefore, option A is correct.
Step-by-step explanation:
As we know that raising to the one-half power i.e.
is the same
as taking the square root.
- so
is the same as the square root of
.
For example, taking the square root of 4 will determine:





so the expression becomes


∵ 
so, 1/2 rational exponent represents a square root.
Therefore, option A is correct.
