80% of 20 is 80/100 x 20 = 16
So, kelly has used 16 stamps, and has 4 left
Since the lines are parallel they have the same slope 2/3. use point slope form to get,
y+2=2/3(x-1)
y+2=2/3x-2/3
y=2/3x-8/3
3y=2x-8
2x-3y=8

YES the ordered pair can satisfy the eqaution
Same number of rows to chairs in a row would form a square.
Use the total number of students as the area
Find the number or rows by taking the square root of student:
The square root of 7033 is 83.86
Round up to 84
Total seats would be rows x seats per row:
84 x 84 = 7,056 total seats
7056 seats - 7033 students = 23 empty seats
Answer:
x=sqrt(y+2), -sqrt(y+2)
Step-by-step explanation:
y=x^2-2
x^2=y+2
x=sqrt(y+2), -sqrt(y+2)
