Answer:
The correct answers are A, C and D.
Step-by-step explanation:
Given the equation 4x - 5y = 24, we substitute the coordinates of the given points to determine whether the equation is then true or not true.
For example, if we focus on point B: (6, 0), x = 6 and y = 0 and the equation becomes 4(6) - 5(0) = 24, which is TRUE.
Doing the same thing with A: (-9, -12), we get 4(-9) - 5(-12) = 24, which is also TRUE.
Check out C: (4, 8): 4(4) - 5(8) = 24. This is FALSE.
Check out D: (1, -4): 4(1) - 5(-4) = 24. This is TRUE.
The correct answers are A, C and D.
Using algebra
3b+5d=34
2b+6d=36
This is a simultaneous equation
Times top equation by two and bottom by 3
6b+10d=68
6b+18d=108
Subtract bottom equation by top one
-8d=-40
d=5
substitute this into an equation
3b+25=34
-25 from both sides
3b=9
b=3

It's hard to tell from the way the question is written.
-- If he has 5 pennies, then it doesn't matter how many he lost.
He has five of them.
-- If he has 5 pennies after he lost three of them, then there are
eight now, just like there were before, but he only has 5 of them.
-- If he had 5 pennies before he lost three, then there are still
5 pennies, but he only has two of them.
