PLEASE HELP !! (2/5) -50 POINTS-

Step-by-step explanation:

Our approach here is to isolate X, and simplify this solution. We want to begin by subtracting matrix 2, as shown below, from either side - the first step in isolating X. Afterwards we can multiply either side by the inverse of matrix 1, the co - efficient of X, such that X is now isolated. We can then simplify this value.

Given,

: Matrix 1

: Matrix 2

( Subtract Matrix 2 from either side )

( Simplify )

( Substitute )

( Multiply either side by inverse of Matrix 1 )

- let's say that this is Matrix 3. Our solution would hence be Matrix 3.

sorry, i'm new here and i'm just trying to figure this out. try quizlet. rate 5* you!

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
