Answer:
Closed boundary point
Step-by-step explanation:
It says greater than OR equal too and having a closed boundary will indicate that 21 is apart of the inequality also.
I hope this helps
It is not A or C, and D isn't specific enough (over what amount of time? is it flying up? down? It is going forward at the same height?) The most likely thing to stay consistent is the cost of fabric and it's length.
Say 1 foot of fabric is $3 (assuming there's no discount for additional feet, but math isn't that consistent with actual store sales), then 2 is $6, and 3 is $9. That is a constant rate of change.
The smallest common denominator is 30 in so
<span>9/10=27/30 and 5/6=25/30 are your answers ; ]</span>
The answer is 6 . Why because 6 -12 =-6
The answer fir the second question mark is -22 . Why because -10-12 =-22
