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

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

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
