The matrices are
S =(4 11                           T= ( -8 11
      -3  -8)                                 3  4 )
Inverse of a matrix is a matrix derived from another matrix such that if you pre- multiply it with the original matrix you get a unit matrix.
if we multiply S and T
 ST will be 
        ( 4 11    ×      (-8 11   = ( 1 0
          -3 -8)           -3 -4)         0 1)
and also TS
          ( -8 11      ×     (4 11  = ( 1 0
             -3 -4)            -3 -8)       0 1)
therefore, matrices S and T are inverses of each other because ST = TS= I

Answer:

C.

Step-by-step explanation:

The answer is C, as as any value of m will make the equation true.

Such as if we used 2 as a substite value for m.

-6(2)-6+8(2)=-5+2(2)-1

Lets simplify both equations:

-6(2)-6+8(2)=-2

-5+2(2)-1=-2

Now, if you want, you can also use any other value for m, but that is basically how I got C. If they equations didn't have the same answer, then it would be B. If it only worked for 2 numbers, then it would be A. Now, I tried this equation again with -3=m, but I still ended up with the same answers. So it wouldn't have been D.

all three sides of triangle x'y'z' must be to the corresponding sides in triangle xyz and the corresponding angles are .
Soloha48 [4]

The required solution is ∠X'≅∠X, ∠Y'≅∠Y and  ∠Z'≅∠Z.

It is required to find the corresponding angles.

<h3>What is angle?</h3>

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle and corner whether constituting a projecting part or a partially enclosed space.

Given :

Corresponding angles are

∠X'≅∠X,

∠Y'≅∠Y

∠Z'≅∠Z

Therefore, the required solution is ∠X'≅∠X, ∠Y'≅∠Y and  ∠Z'≅∠Z.

Find the slope of the line through the pair of points.
solong [7]

Answer:

B

Step-by-step explanation:

The formula to determine slope is \frac{y-y}{x-x}.

Knowing this you can fill in the formula with the numbers: \frac{2-4}{-8+9}

2 - 4 is -2, so the numerator is -2.

-8 + 9 = 1, so your denominator is 1.

 

Therefore, your fraction is -\frac{2}{1}, or simply -2.
