Help? (18x - 9 > 9) and (2x - 4 > -10)

4vir4ik [10]

Answer:

x>1 the bottom graph

Step-by-step explanation:

(18x - 9 > 9) and (2x - 4 > -10)

Do the first inequality first

18x - 9 >9

Add 9 to each side

18x - 9+9 > 9+9

18x> 18

Divide each side by 18

18x/18 > 18/18

x >1

Then the second inequality

(2x - 4 > -10)

Add 4 to each side

2x-4+4>-10+4

2x>-6

Divide each side by 2

2x/2 >-6/2

x>-3

Since this is an and

x>1 and x>-3

We take the more restrictive

x>1

Suppose that A, B, and C are invertible matrices of the same

STALIN [3.7K]

Answer:

Step-by-step explanation:

Given that t A, B, and C are invertible matrices of the same

size.

To pr that $(ABC)^{-1} = C^{-1}B^{-1}A^{-1}.$

to pr that $( ABC) (C^{-1}B^{-1}A^{-1})=e$

LS= $( AB(C (C^{-1})B^{-1}A^{-1})\\=ABIB^{-1}A^{-1})\\=A(BB^{-1})A^{-1})\\=AA^{-1})\\=I$

Thus proved
