For which values of a does 2a − 6
6a 4a − 12
have an inverse matrix?

The matrix does not have an inverse.

Step-by-step explanation:

Since the determinant of the matrix is zero it is called a singular matrix.

Singular matrices do not have an inverse.

Hence, the matrix does not have an inverse.

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
