Answer:
Number line D is true
Step-by-step explanation:
Given
![-3x + 1 < 7](https://tex.z-dn.net/?f=-3x%20%2B%201%20%3C%207)
See attachment for number lines
Required
Which number line makes the inequality true
First, we solve for x in ![-3x + 1 < 7](https://tex.z-dn.net/?f=-3x%20%2B%201%20%3C%207)
![-3x < 7 - 1](https://tex.z-dn.net/?f=-3x%20%3C%207%20-%201)
![-3x < 6](https://tex.z-dn.net/?f=-3x%20%3C%206)
Divide through by -3
![\frac{-3x}{-3} < \frac{6}{-3}](https://tex.z-dn.net/?f=%5Cfrac%7B-3x%7D%7B-3%7D%20%3C%20%5Cfrac%7B6%7D%7B-3%7D)
![x > -2](https://tex.z-dn.net/?f=x%20%3E%20-2)
The inequality means x is greater than -2.
This means that, the line must point to the right of -2 and the "greater than" means that the circle must be opened
Number line D is true
Answer:
Any line with the same slope. In this case the slope is 1. For example, y=x+4 is parallel to y=x+7.

Answer:
198 cm³
Step-by-step explanation:
V = π r² h
V = 22/7 × 3² × 7
V = 22/7 × 9 × 7
V = 22 × 9
V = 198 cm³
