Given the following matrices, find 3A - 2B. (Hint: find 3A and 2B first and then subtract.)

1 answer:

7 0

Its A
When you multiply a constant k to a matrix, you multiply all the corresponding numbers in the matrix by k.
So 3A would be = 3 9 15 6 and 2b would be = 8 18 0 6 Now subtract it. to get your answer

As parallel sides

$\\ \rm\longmapsto 2x+90=180$

$\\ \rm\longmapsto 2x=90$

$\\ \rm\longmapsto x=90/2=45$

Now

$\\ \rm\longmapsto 2x+3y+6y+90=360$

$\\ \rm\longmapsto 9y+180=360$

$\\ \rm\longmapsto 9y=180$

$\\ \rm\longmapsto y=20$

Complete the ordered pair for the given equation. (_,-1);y=-3/5x-7

Fiesta28 [93]

Hi!

So for this problem, we're given the y-coordinate and we can plug that in for y in the equation. So let's do that

-1 = -3/5x - 7
6 = -3/5x
30 = -3x
-10 = x

The missing coordinate would be x, assuming that the equation was y = (-3/5)x - 7
