Which sequence is modeled by the graph below?
coordinate plane showing the points 2, 1; 3, 3; and 4, 9
an = one third(27)n − 1
an = 27(one third)n − 1
an = one third(3)n − 1
an = 3(one half)n − 1

C is correct.

Step-by-step explanation:

We need to choose correct model by the graph which passes through the points (2,1) (3,3) and (4,9)

Option 1:

Put n=2 and to get a₂=1

False

Option 2:

Put n=2 and to get a₂=1

False

Option 3:

Put n=2 and to get a₂=1

TRUE

Similarly, we will check (3,3) and (4,9)

and we will get true

Hence, The sequence is

step-by-step explanation:

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
