Original Price = $20
Discount = 40%
First Calculate the discount amount by multiplying the original price (20) by the percentage discount in decimal form ( divided by 100)
20 x (40/100) = 20 x 0.4 = 8
Then subtract the discount amount to the original price:
20-8 = 12
Sale price : $12
Answer:
(3, 6)
Step-by-step explanation:
You add the x points together and divide by two, then you add the y points together and divide by 2.
Weird that the only choices are given as integrals with respect to

. (Integration along the

axis would be way easier, but whatever)
The fourth option should do it.
C=2πr r radius it would be right
Multiply the first equation by -1
-3x-y=-4
2x+y=5
Add them up
-x=1
So x=-1
And y=7
So the first option is correct
