Answer:

Last option, Option D

Step-by-step explanation:

The given inequality is |x| + 1 < 3

Then interpret this as

x + 1 < 3

x + 1 - 1 < 3 -1

x < 2

-x + 1 < 3

-x + 1 -1 < 3 - 1

-x < 2

x > 2

Therefore -2 < x < 2 is the solution and we can graph as option D the last option.

What is the next number? 2+3=8 3+7=27 4+5=32 5+8=60 6+7=72 7+8=?

Answer:

Step-by-step explanation:

2 + 3 = 8

8 : 2 = 4; 4 - 1 = 3 (subtract 1)

3 + 7 = 27

27 : 3 = 9, 9 - 2 = 7 (subtract 2)

4 + 5 = 32

32 : 4 = 8; 8 - 3 = 5 (subtract 3)

5 + 8 =60

60 : 5 = 12, 12 - 4 = 8 (subtract 4)

6 + 7 = 72

72 : 6 = 12, 12 - 5 = 7 (subtract 5)

7 + 8 = x

x : 7 = y, y - 6 = 8 (subtract 6)

Solve:

y - 6 = 8 add 6 to both sides

y - 6 + 6 = 8 + 6

y = 14

x : 7 = y ⇒ x : 7 = 14 ⇒ x = (14)(7) ⇒ x = 98
