Answer: 3/8
Step-by-step explanation: If you put it into the slope formula, you would get 18 - 9 / 19 - (-5) which simplifies to 9/24 and then to 3/8.
//I'll let x = $5, y = $10
x + y = 13
5x + 10y = 90
So, y = 13 - x
5x + 10(13 - x) = 90
5x + 130 - 10x = 90
-5x = -40
x = 8
Answer:
It's symmetrical to the origin
Step-by-step explanation:
Use desmos for further graphing
Initial balance : 463.76
refunds : 12.56 + 52.11 + 26.03 = 90.70
sales : 101.32 + 10.98 = 112.30
463.76 - 90.70 + 112.30 = 485.36 is the correct balance
so there is a (511.39 - 485.36) = 26.03 difference
so the mistake made was instead of subtracting the 26.03 refund, she added it as a sale
