Find the determinant for the 3 by 3 matrix given. Consider the determinant.

The determinant of the matrix given is -49

Step-by-step explanation:

We are given determinant

The determinant can be found as follows

Now solving:

So, determinant of the matrix given is -49

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
