Explain why the system cannot be solved by matrix inverse methods. Discuss methods that could be used and then solve the system. x 1 minus 2 x 2 minus 2 x 3 equals negative 7 2 x 1 minus 7 x 2 plus 3 x 3 equals negative 16 x 1 minus 5 x 2 plus 5 x 3 equals negative 9

the correct is answer is a 9-sided polygon!

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
