Best ResponseYou've already chosen the best response.1if x5 >0 , then x5=3 if x5 <0, then x(5)=3; x+5=3

Best ResponseYou've already chosen the best response.1since x is a variable, you can't say x5 is > or < than 0, so you must consider both cases (unless the question tells you if it is < or >)

Best ResponseYou've already chosen the best response.1linear function means the graph will be a straight line so, if you take the same deltax for diferent x's, there should be the same deltay in both cases I guess it's a bit confuse  sorry I can't explain the right way cause my english is poor...

Best ResponseYou've already chosen the best response.1like if you pick up x1=1, y1=1 & x2=2, y2=3 for any other deltax = x2x1 = 1, there should be the same deltay = y2=y1 = 4

Best ResponseYou've already chosen the best response.0Bradley and Ryan are having a contest to see who can collect the most bumper stickers. Bradley started with 23 bumper stickers and plans to add 4 each month. Ryan has 9 bumper stickers and plans to add 6 each month. After how many months will they have the same number of bumper stickers? (1 point) 10 months 2 months 7 months 51 months

seidi.yamauti

Best ResponseYou've already chosen the best response.1a way to solve it is writing the equations of stickers collected by each of them

seidi.yamauti

Best ResponseYou've already chosen the best response.1being m = months, then Bradley: Stickers=23+4m Ryan: Stickers=9+6m

seidi.yamauti

Best ResponseYou've already chosen the best response.1it means BRadley has 23 stickers and owns 4more each month and Ryan has 9 stickers and owns 6 more each month

seidi.yamauti

Best ResponseYou've already chosen the best response.1it is the same as the previous, and you can just write y=23+4x y=9+6x you want to know x

seidi.yamauti

Best ResponseYou've already chosen the best response.1Sure you know! Bradley: [number of stickers]=23+4x Ryan: [number of stickers]=9+6x

Best ResponseYou've already chosen the best response.1if you call number of stickers as 'y' then you see that y MUST be the same in both equations
