Let A= ????

hjlf

Answer:

X = $\begin{bmatrix}5 &-1 \\ -5 &4 \\2& -9\end{bmatrix}$

Step-by-step explanation:

given,

A + X = Q

X = A - Q

A = $\begin{bmatrix}3 &2 \\ -1 &5 \\3& -4\end{bmatrix}$

Q = $\begin{bmatrix}-2 &3\\ 4 &1 \\ 1&-5\end{bmatrix}$

now

X = $\begin{bmatrix}3 &2 \\ -1 &5 \\3& -4\end{bmatrix}-\begin{bmatrix}-2 &3\\ 4 &1 \\ 1&-5\end{bmatrix}$

X = $\begin{bmatrix}3-(-2) &2-3 \\ -1-4 &5-1 \\3-1& -4-5\end{bmatrix}$

X = $\begin{bmatrix}5 &-1 \\ -5 &4 \\2& -9\end{bmatrix}$

hence, the required matrix is given above

Use a graphing calculator to find the value of f(x) when x = 2 for the function f(x)=x2-5.

max2010maxim [7]

Answer:

-1

f(2)= 2* 2 - 5 = -1

but if you meant f(x)=x²-5

its

f(2)=2²-5 = 4-5 = -1

it's indeed not the same for all other values of x, for example x=3!

(would really appreciate the brainliest)

Gracelyn has multiple sticks of different lengths to build a triangle for a class project.Which 3 lengths could gracelyn choose

Goryan [66]

I think it should be D because if you look it is kind of common sense on how a triangle should look you should draw it out
