H is equal to 8
M is equal to 15.3
20-12= 8
9+6.3= 15.3
Hope this helped

Step-by-step explanation:
Here is how to work it with long division.
Answer:
C) It is not possible. He needs to lose at least 5 lbs a week
Step-by-step explanation:
This would not be possible. To know, you have to plug 10 into the function:
-4(10) + 250 = 210
After getting this value, ou have to take it away from 250:
250 - 240 = 40 → This 40 represents the value for the amount of pounds lost
40 is less than 50, so he would have to lose more than 4 pounds a week
To see if losing 5 pounds is enough, replace the -4 from the function with a -5:
-4x + 250 = 210 → -5x + 250 = 210
From here plug in 10 just like the previous time:
-5(10) + 250 = 200
From here take 200 away from 250 to find the pounds lost in 10 weeks:
250 - 200 = 50
50 is equal to the goal of 50 pounds, so therefore, Luke needs to lose at 5 pounds a week
The center of the circle is the midpoint of the points or ((-4+6)/2,(-3+3)/2)=(1,0). Now, the diameter is the distance between the points. Using distance formulas (or noticing that the y-values are the same so it is a horizontal line), the distance is 10. Therefore, the radius is 5. The equation of a circle is (x-a)^2+(y-b)^2=r^2 where (a,b) is the center. Therefore, the equation is (x-1)^2+(y-0)^2=5^2.
