Answer: C: Expression B and D
Step-by-step explanation:
Say the item is $100. 20% of 100 is equal to 100 (20/100)
When you simplify, it equals 20. So 20% of 100 is 20. This $20 is the amount of discount you receive.
So you have to subtract $20 from the $100 to find the sale price. The sale price is $80.
Now plug in 100 for p in each equation. The equation that equals 80 is the answer.
Only equation B and D equals 80 when 100 is plugged in.

Answer: x-coordinate: 4
y-coordinate: -2
Step-by-step explanation:
The given system of linear equations:
y= x- 6 ..(i)
5x+3y = 14 ...(ii)
Substitute value of y in (ii), we get
Put value of x in (i) , we get
Hence, Required solution:
x-coordinate: 4
y-coordinate: -2
