Given matrices g and h below, which statement is true?

g= 7 5
4 3

h= -6 -5
-4 -2

a.) matrices g and h are not inverses of each other because g + h does not equal i.

b.) matrices g and h are not inverses of each other because gh does not equal i.

c.) matrices g and h are inverses of each other because gh = i.

e.) matrices g and h are inverses of each other because g + h = i.

Option B.

Step-by-step explanation:

The given matrices are

Two matrices are inverse of each other if product of both matrices is identity matrix, i.e., .

Matrices G and H are not inverses of each other because GH does not equal I.

Therefore, the correct option is B.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
