Answer:
B = (-11, -17)
C = (11, -17)
Step-by-step explanation:
Reflection over the x-axis is accomplished by changing the sign of the y-coordinate:
(x, y) ⇒ (x, -y) . . . . . reflection over x-axis
Reflection over the y-axis is accomplished by changing the sign of the x-coordinate:
(x, y) ⇒ (-x, y) . . . . . reflection over the y-axis
__
B = (-11, -17)
C = (11, -17)

<em>Check</em>
Reflection over both axes negates both coordinates. It is equivalent to reflection over the origin, or rotation 180°.
A(-11, 17) ⇒ C(11, -17) . . . . . both coordinates change sign

Step-by-step explanation: Opposite sides of a parallelogram are equal.
Explanation:
Discount = 20%
The cost of 5 notebooks = $10
The cost of 1 notebook before applying discount = $10/5 = $2
Applying the discount on the original price:
Discount = $10 × 20% = 10 × 0.20
Discount = $2
The sales price of the 5 notebooks = original price - discount
The sales price of the 5 notebooks = $10 - $2
The sales price of the 5 notebooks = $8
The sales price of 1 notebook = $8/5
The sales price of 1 notebook = $1.6
The amount saved per notebook = The cost of 1 notebook before applying discount -
$2 -
