3,-7 is the answer for this question
Answer:
The answer to your question is B = B (3, -7)
Step-by-step explanation:
Data
A = (-6, 5)
M = (-1.5, -1)
Process
1.- Write the formula of Midpoint
Xm = (x1 + x2)/2
Ym = (y1 + y2)/2
2.- Solve for x2 and y2
x2 = 2Xm - x1
y2 = 2Ym - y1
x1 = -6 y1 = 5 Xm = -1.5 Ym = -1
3.- Substitution
x2 = 2(-1.5) + 6
y2 = 2(-1) - 5
4.- Simplification
x2 = -3 + 6
y2 = -2 - 5
5.- Result
x2 = 3
y2 = -7
B (3, -7)

The elephant lost 4 pounds each month. Because he is losing weight, and not gaining weight, you have to make the answer negative
-2x + 16 < = 10
-2x < = 10 - 16
-2x < = - 6
x > = -6/-2
x > = 3............so any number that is 3 or above is in the solution set
