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
.
Angle C equals 63
Add angle 17 plus 100 and the subtract the answer from 180. Because a triangles are always 180 degrees
Answer:
11
Step-by-step explanation:
5 1/2 x 2= 11
$6.90 :)
You add $0.35 to the $6.55 that the apple juice cost. That would get you to $6.90
Answer: B = (6,-8)
Step-by-step explanation:
first the midpoint formula is 
then you take the x co-ordinate of A and substitute it into one of the x values in the first part of the formula:

then solve it like an equation:

then you take the y co-ordinate of A and substitute it into one of the y values in the second part of the midpoint formula:

then solve it like an equation:

∴ the answer is x=6, y= -8
which is expressed as a point, B(6,-8)
