Answer:
x =
Step-by-step explanation:
The question states that it is the square root of the sum of both n and 6. That means n and 6 are added first before square rooted. Between B and C, choose the answer that has the parenthesis around x and 6, like (x + 6).
Answer:
Step-by-step explanation:
We are given that a matrix equation
We have to solve the given matrix equation for X.
Suppose all matrix are invertible.
Left multiply by on both sides then ,we get
When A is invertible.
(
Right multiply by BA on both sides then we get
(XI=X)
Answer: Option B.
Step-by-step explanation:
Given the system of inequalities:
The solution of the system of inequalities is the region between the parabolas. This region is: below the parabola and above the parabola
Then, if a point is a solution of the system, then it must be in the region between this parabolas.
You can observe in the figure attached that the point that is in this region is the point (2,6), therefore, the answer is the option B.
