Suppose that: a) E1 [ -4 2 ] = [ -8 4 ] , find E1 and E1^(-1) [ -4 4 ] [ -4 4 ]
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
Suppose that:
a) E1 [ -4 2 ] = [ -8 4 ] , find E1 and E1^(-1)
[ -4 4 ] [ -4 4 ]
b) E4 [ -5 4 3] = [ -5 4 3 ] , find E4 and E4^(-1)
[ -4 1 2 ] [ -12 3 6 ]
[ -5 -1 2 ] [ -5 -1 2 ]
c) E6 [ -5 4 3 ] = [ -5 4 3 ] , find E6 and E6^(-1)
[ -4 1 2 ] [ -4 1 2 ]
[ -5 -1 2 ] [ -30 19 17 ]
