2. when x = -2 it is 10 am because when x is 0, it is noon, or 12 pm, her elevation is 7 meters above sea level
3. when x is 1, it is 1 pm, and her elevation is 0 meters
 
        
             
        
        
        
Answer:
20 x 20 feet
Step-by-step explanation:
First I just drew out two squares, one was the first un-cut square and the second is the cut one. Since we know that the area of the smaller square is 144, and Area is just side^2 , we know that all the sides of the smaller square are 12. Now, all we have to do is add 8 to 12 to get the original lawn. The original lawn was a 20 x 20 ft lawn.

Answer:
   $491.65
Step-by-step explanation:
The pay for the first 8 hours is $5.40 per hour × 8 hours = $43.20. Hours over 8 are paid at 1.5 × $5.40 = $8.10 per hour. There are at least 8 hours every day for the 6-day week. There are hours over 8 on Monday, Wednesday, Thursday, and Friday totaling 7 hours of overtime.
The amount of sales is more than $3000, so 4% will be paid on $3000, and 5% will be paid on the $1115 in excess of $3000.
So, the gross pay is ...
   $43.20 × 6 + 8.10 × 7 = $315.90 . . . . wages
   $3000 × .04 +1115 × .05 = $175.75 . . . commission
   $315.90 +1.75.75 = $491.65 . . . . gross pay for the week
