Need the answer to bring up my grade.

D

Step-by-step explanation:

Substitute the initial value x = - 12  and successive values into f(x)

f(- 12) = 2(- 12) + 10 = - 24 + 10 = - 14

f(- 14) = 2(- 14) + 10 = - 28 + 10 = - 18

f(- 18) = 2(- 18) + 10 = - 36 + 10 = - 26

f(- 26) = 2(- 26) + 10 = - 52 + 10 = - 42

The first 5 iterates are

- 12, - 14, - 18, - 26, - 42 → d

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
