Answer:
£9.6
Step-by-step explanation:
x = the original price of a CD
£x = 100% of the original price
The price of a CD was decreased by 20% to £7.68.
This means:
£7.68 = 100% - 20%
£7.68 = 80% of the original price
From this, we will find 1% of the original price.
£7.68 ÷ 80 = 1%
£0.096 = 1%
Since the original price ( x ) = 100% of the original price, we will find 100% of the original price.
£0.096 × 100 = 100%
£9.6 = 100%
Therefore, the original price of a CD = £9.6
Answer:
y=2x-2
Step-by-step explanation:
2x-y=2
+y +y 1)add y to both sides
2x=y+2
-2 -2 2) Substract 2 from both sides
2x-2=y
y=2x-2 3) Use the Refelxive POE to flip the sides

What are the options? could you type it out a little more clear if possible? thanks!
Answer:
(x = 0,y = 0),(x = 1, y = 4),(x= 2, y =8)
Step-by-step explanation:
the rule is to multiply x by 4.
when x = 0, y =4(0) = 0
when x = 1, y =4(1) = 4
when x = 2, y =4(2) = 8
