First you would divide 53 by 100 which is .53
Then you would multiply that by 20 and get 10.6 which would be your tip
Next you would do .53 times 6 which is 3.18. Add that to 53 and get 56.18

What do these questions mean?? relations part two only btw

I'll do problem 1 to get you started.

========================================

1a. Pick any four ordered pairs of the form (x,y) such that y = 2x. In other words, these points are all on the line y = 2x.

Four such points are: (1,2), (2,4), (3,6) and (4,8)

There are infinitely many points to pick from.

========================================

1b. Similar to the first problem, but now y = x+5. Whatever the x coordinate is, we add 5 to it to get the y coordinate.

Four such points are: (0,5), (1,6), (2,7), (3,8)

There are infinitely many points

========================================

1c. Similar idea as before, but now y = x-4

Four points on this line are: (0,-4), (1,-3), (2,-2), (3,-1)

There are infinitely many points.

=======================================

1d. Take half of the x coordinate to get the y coordinate. The equation is y = x/2 or y = (1/2)x or y = 0.5x

Four points on this line are: (2,1), (4,2), (6,3), (8,4)

There are infinitely many points.
