Answer:
(-∞, 6]
Step-by-step explanation:
Step 1: Write inequality
5x - 10 ≤ 20
Step 2: Solve for <em>x</em>
- <u>Add 10 to both sides:</u> 5x ≤ 30
- <u>Divide both sides by 5:</u> x ≤ 6
Here we see that any value less than or equal to 6 would work.
∴ the 3rd option is our answer.

So this problem is asking you to plug numbers in for t. 0 1 2 3 4 5. So your first equation would be 2× 0+8 and you would get 8 so for 0 toppings you would pay 8 dollars then graph this over 0 up 8. Next equation 2×1+8 is 10. Graph. over 1 up 10. Next 2×2+8 is 12. Graph. Over 2 up 12. next 2× 3 + 8 is 14. Graph. Over 3 up 14. Next 2×4+8 is 16 so over 4 up 16. Last 2×5+8 is 18 so over 5 up 18. Your Y-intercept is the dot that is on the y axis and in this problem that is 8. This means if you buy 0 toppings you will spend 8 dollars.
