For E the answer is 2. Because the square of 1 is one and 9 is three. And 2 to the square root of two which would be 2 time 2= 4
You're trying to find constants

such that

. Equivalently, you're looking for the least-square solution to the following matrix equation.

To solve

, multiply both sides by the transpose of

, which introduces an invertible square matrix on the LHS.

Computing this, you'd find that

which means the first choice is correct.
Answer:
32
Step-by-step explanation:
it multiplies by -2 every time
Answer:
X= -14
Step-by-step explanation:
So we can first simplify the equation
2x+10=x-4
Now just solve i normally
x+10=-4
x=-14
So x is -14
