Answer:
The answer is c. Sorry my last answer was wrong i think. If its abc its probably the other way around i didnt see which way it was going. Though if i was right the first time its either a or c
Step-by-step explanation:
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:
The computer loses 50%, percent of its value each year.
Step-by-step explanation:
See the graph attached.
A computer is sold for a certain price and then its value changes exponentially over time.
It is clear from the graph that at t = 0, the price was $500, then at t = 1 year, the price was $250 and at t = 2 years, the price was $125 and at t= 3 years, the price was $62.5 and so on.
Therefore, the computer loses 50%, percent of its value each year. (Answer)
