Answer:
The correct answer is x < 2 or x > -2. The graph would be a line between -2 and 2 with an open circle on both.
Step-by-step explanation:
To solve, first solve the equation for the absolute value portion of the equation.
2|x| + 1 < 5
2|x| < 4
|x| < 2
Now since there is an absolute value around it, we have to complete it for the positive and negative versions.
x < 2 OR x > -2
The volume of the solid generated when the right triangle below is rotated about side is 564.2.
<h3>How to calculate the volume?</h3>
The volume will be calculated by using the formula:
= 1/3πr²h
where, r = 7
h = 11
Therefore, the volume will be:
= 1/3πr²h
= 1/3 × 3.14 × 7² × 11
= 564.2

(79 + 93 + 91 + 68 + x) / 5 = 80
(331 + x) / 5 = 80.....multiply both sides by 5
331 + x = 80 * 5
331 + x = 400
x = 400 - 331
x = 69 <=== he would have to make at least a 69
