Answer:
B(5, 4)
Step-by-step explanation:
The midpoint formula is ...
M = (A +B)/2
Solving for B gives ...
B = 2M -A
B = 2(1, -2) -(-3, -8) = (2+3, -4+8) = (5, 4)
The coordinates of B are (5, 4).

9000
Step-by-step explanation:
If you divide 20000 by 100 I multiplied by 15 and multiplied that by 3 tell me if it was right.
Answer:
- 9x² + 10x + 4
Step-by-step explanation:
Calculate the subtraction as
- 4x² + 2x - 8 - (5x² - 8x - 12 ) ← distribute parenthesis by - 1
= - 4x² + 2x - 8 - 5x² + 8x + 12 ← collect like terms
= - 9x² + 10x + 4
423%. Calculate this with
2(2,1)(14,10)
(4,2) - (14,10)= (-10, -8)
The coordinates of K are (-10, -8).
