Answer:


Step-by-step explanation:
The vertices of quadrilateral ABCD are A(1,0) B(5,0) C (7,2) D(3,2).
The slope of side AB is

The slope of side BC is

The slope of side CD is

The slope of AD is



We see that the opposite sides of the quadrilateral ABCD are equal.
Hence the quadrilateral is a parallelogram
Answer:
0.1
Step-by-step explanation:
r = y/x
r = 1.4 / 14 = 0.1
1.5*100% = 150%
The book is worth 150% of the original amount.
.40•32=amount spent on snacks
.14•32=amount spent on school supplies
32-((40•32)+(.14•32))=amount saved per week
