Answer:
B-The graph is incorrect. He should have shaded to the right of –8.
Step-by-step explanation:
We examine the steps Alfonso follows in graphing the inequality x > -8.
Step 1: Draw a number line, and place an open circle at –8.
A number line going from negative 13 to negative 3. An open circle is at negative 8.
The first step is correct, since we use an open circle for > or < and a closed circle for
.
Step 2: Shade to the left of –8 to represent the infinite solutions to x greater-than negative 8.
This step is incorrect since <u>values to the left are always less than.</u>
He should have shaded to the right of -8.
<u>The error made is Option B. </u>
CHECK:
x=-7
-7>-8 (TRUE)

Answer:
40 shows
Step-by-step explanation:
Seth’s father has spent $140.
At the regular price, the number (n) of shows Seth could attend is
n = 140/3.50
n = 40
If Seth attends 40 shows at that price, he will have spent $140.
Every show after that will cost only $1 instead of $3.50.
Seth must attend 40 shows for it to benefit his father.
