Can someone please let me know if these are the correct answers
Lostsunrise [7]

1. x >= 4, because 4 is dotted, and that means that 4 is included

2. x =/ 4, the third answer is correct, because all numbers except 4 are included

3. the first number line is the correct answer, because -3 is not included

4. the second number line is the correct answer, because -1 is included

5. the second number line is the correct answer, because 6 is not included

6. the first number line is the correct answer, because 0 is included

7. the second number line is the correct answer, because all numbers except -4 are included

8. the third number line is the correct answer, because -1,5 is included

When a number is included in an interval, it should have full dot on the number line, so that's how you know.

Hope this helps!

Yolanda spends 82/3 hours per month playing soccer. Approximately how many hours does she play soccer in a year?
Vesnalui [34]
328 because 82/3 multiplied by 12 is 328 and you do that because there's 12 months in a year and if you spend 82/3 hours per month playing soccer than you would multiply that by 12 which gives you 328 hours.

Could someone please help ?
blondinia [14]

Answer:

No

Step-by-step explanation:

Put x = 2 into both equations:

For x- 10 = 2-10 = 8 (Not  > 8)

For -0.5x-4 = -0.5*2-4 = -5 (Not < -8)

Hence, the answer is no.
