Are the ratios 4:6 and 1:2 equivalent?

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)

Which situation can be modeled by the inequality 5 + 10w ≥ 45? a. you start with $5 and save $10 a week until you have at least $45. b.you start with 5 baseball cards and purchase 10 cards every week until you have at most 45 cards. c.you start with 5 water bottles and purchases cases of 10 water bottles each until you have a total of 45 water bottles. d.you spend $5 plus $10 per week until you have less than $45.

This graph shows which inequality? a ≤ –3 a > –3 a ≥ –3 a < –3
