Step-by-step explanation:
To simplify the ratio of 221:289, you must find a common factor between the two numbers. In this case, they share 1 and 17. Use 17, and divide both numbers by it. You'll end up with 13:17 as your simplified ratio.
Answer:
-50x+40
Step-by-step explanation:
It depends on the variable.
If it's something like x < 2, your graph would be a vertical line at x = 2, and everything to left of that line shaded in (because of the less than).
Similarly for y, except it would be a horizontal line with either everything above or below shaded.
You can have other equations like 0<x<4 where everything between x = 0 and x = 4 would be shaded
