To find the inverse of a matrix on a Casio fx-991MS scientific calculator, you first need to input the matrix you want to find the inverse of. Then, press the "SHIFT" button followed by the "MODE" button to access the matrix mode. Select the matrix you want to invert by pressing the corresponding number key. Next, press the "SHIFT" button followed by the "MATRIX" button, and then press the "x^-1" button to calculate the inverse of the matrix.
fx=5x1 / 9

g(x) = x/2
y=x

-14x-7 = 35 -14x = 35+7 -14x = 42 x = -3
14x + 6 = 6 14x + 6 - 6 = 6 - 6 14x = 0 14x / 14 = 0 / 14 x = 0
-14x
If f(x)=(5x-1)/9 Then the inverse is x=(5y-1)/9 9x=5y-1 9x+1=5y (9x+1)/5=y The inverse is f(x)=(9x+1)/5
-11
If: -14x = -98 Then: x = 7
