Quadrilateral ABCD with vertices A(-9, 2), B(-8, 8), C(-4, 6), and D(-2, 2) is shown. You want to reflect quadrilateral ABCD in
telo118 [61]

Answer:

See explanation.

Step-by-step explanation:

Graph the quadrilateral. By inspection, you can tell where the midpoint is. (see attachment 1)

Now, I'll draw a line through it. (see attachment 2)

To reflect across a line, think about the points traveling across the line the same number of spaces the point is from the line. For example, point A is three away from the line. So, A' will be 3 away from the other side. The coordinates will be at (-3,2). (see attachment 3).

Do the same for the other points, and you'll have your image.

Please help I’ve been stuck on it forever. :(

Answer:

$31.37 is the sale price

Step-by-step explanation:

All you need to do to find the discount price (sale price) is multiply the price of the item by the decimal form of the percentage.

1. Store A. 40% off the original price of $159.99

(159.99 * .40) = 63.996

63.996 is the discount price we are looking for

2. Store B. 25% off the original price of $130.50

(130.50 * .25) = 32.625

32.625 is the discount price we are looking for

3. Now to find their difference you just subtract the two values.

($63.996 - $32.625) = $31.371

The discount price (sale price) is $31.371
