Answer:
Step-by-step explanation:
- The sum of a number n and 5 => n + 5
- Thrice the sum of a number n and 5 => 3(n + 5)
- At most means "less than or equal to", the sign of which is "≤"
<u>So, the inequality will be:</u>
3(n + 5) ≤ 100

<h3>~AH1807</h3>For the function: y = x² + 4
- y intercept: (0, 4)
- x intercept: None
- vertex: (0, 4)
For the function: x² - 4
- y intercept: (0, -4)
- x intercept: (-2, 0) and (2, 0)
- vertex: (0, -4)
For the function: 1 - x²
- y intercept: 1
- x intercept: (1, 0) and (-1, 0)
- vertex: (0, 1)
Conclusion:
green line = x² + 4; blue line = x² - 4; black line = 1 -x²
