Answer:

Step-by-step explanation:

If there is a 2x2 matrix as $\left[\begin{array}{ccc}a&b\\c&d\\\end{array}\right]$

The determinant is given by $\frac{1}{ad-bc}\left[\begin{array}{ccc}d&-b\\-c&a\\\end{array}\right]$

<em>Now, if we calculate the value of "ad - bc", we see that:</em>

$(-4)(-12)-(8)(6)=0$

We can't calculate the inverse, the inverse doesn't exist. The answer is D.

-6h plus 4 - 3plus h equals 11

olga55 [171]

$- 6h + 4 - 3 + h = 11$
So we start by combining like terms;
$- 6h + h = - 5h$
$4 - 3 = 1$
Now we have;
$- 5h + 1 = 11$
We then subtract 1 from both sides;
$- 5h + 1 = 11$
$- 5h = 10$
Then we divide both sides by 5;
$- 5h = 10$
$- 5h \div - 5h = h$
$10 \div - 5h = - 2$
Leaving the final answer to be h = -2
