Answer:
a
Step-by-step explanation:
Let Sister's age now = s
So Larry is now s + 8
In THREE Years Sister = s + 3
Larry = {s + 8} + 3
But We are told that he will be TWICE as old as Sister is NOW!!!
So s + 11 = {2s}
Solve s = 11
So Sister is ELEVEN Years old and Larry is NINETEEN Years old.
Answer: (9, -3), (1, -1), (0, 0), and (4, 2)
<u>Step-by-step explanation:</u>
Inverse is when the x's and y's are swapped:
The given points are: {(-3, 9), (-1, 1), (0, 0), (2, 4)}
The inverse points are: {(9, -3), (1, -1), (0, 0), (4, 2)}
1. 12/2 = 6
2. 18/6 = 3
3. 40/8 = 5
4. 36/9 = 4
