3/4= 0.75. So the aanswer is .75
Take 19.95 and subtract 17.85 from it to get 2.10. Divide 2.10 by 19.95 to get 0.105. Multiply that by 100 and you get 10.52. So it's 10% or maybe 11% if you're supposed to round. Hope this helps
-4 and 3 are integers
-2.9 is a real number
5/8 is rational, due to the fact that it can be put into a fractional form.
haha lol I was looking for the answer too, but I solved it! Here it is:
Answer:
The slope of line s is b/a. Rotate line s 90° clockwise about the origin to get line t. The labeled points on line s map to (0, a) and (b, 0) on line t. The slope of line t is -a/b. The slopes of the lines are opposite reciprocals because the product of the slopes is -1.
