Step 1: Draw a number line, and place an open circle at 8, 13-1211-109-8-7 -8-5 4-3
Step 2: Shade to the left of9 to represent the infinite solutions to x-8.
13-12-11-10-9 -8-7 -8-5-4 3
Step 3: Check work by substitution.
X-9
-9>-8 False
Which best describes the situation?
O The graph is incorrect. He should have used a closed circle at-8.
O The graph is incorrect. He should have shaded to the right of -8.
O The graph is correct. He should have checked his work with a number that was not on the shaded portion of the
graph.

:

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
