If the original price was $10 more than the sale price, so we know that in this case, 20% = $10. Because 20% is equivlalent to , multiply $10 by 5 to get the answer of $50.
1. Point A(-5,8) is reflected across the line y = x. What are the coordinates of A'? Show your work and explain.
1 answer:
Answer:
The coordinates of A'(8,-5)
Step-by-step explanation:
we know that
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places
so
The rule of the reflection across the line y=x is
(x,y) -----> (y,x)
we have the point A(-5,8)
Applying the rule of the reflection across the line y=x
A(-5,8) ----> A'(8,-5)
see the attached figure to better understand the problem

Well, split it into 3 shapes
21 x 10 = 210
3 x 6 = 18
2 x 6 = 12
210 + 18 + 12 = 240 square cm
