What is the value of d in the matrix equation below?

9 11

-14 5

Step-by-step explanation:

D is doing to be a 2 by 2 matrix

a  b            -1  -15          8  -4

c  d     +     0   7      =    -14  12

The corresponding terms get added together to equal the corresponding term on the right.

a + -1 = 8

Add 1 on each side

a -1 +1 = 8 +1

a = 9

b + -15 =-4

Add 15 to each side

b-15+15 = -4+15

b =11

c+0 = -14

c = -14

d +7 = 12

Subtract 7 from both sides

d+7-7 = 12-7

d = 5

The  matrix is

9 11

-14 5

44

step-by-step explanation:

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.
