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

Best ResponseYou've already chosen the best response.0since 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.0linear 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.0like 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.0For the data in the table, does y vary directly with x? If it does, write an equation for the direct variation. x y 3 6 6 18 8 24 (1 point) yes; y = 2x yes; y = 3x yes; y = 4x no; y does not vary directly with x

Best ResponseYou've already chosen the best response.0Write the equation of a line that is perpendicular to the given line and that passes through the given point. y = –1/3x + 5; (4, 3) y = –3x + 15 y = 3x – 9 y = –4x + 3 y = –1/3x – 11

Best ResponseYou've already chosen the best response.0to be perpendicular, the multiplication of the slopes' values must be 1, is it right?

anonymous

Best ResponseYou've already chosen the best response.0the equation you need to find is y=ax+b a.(1/3) = ? then substitute (4;3)

Best ResponseYou've already chosen the best response.0subtracting the first by the second, you have 0=5x25 this gives you x=5

anonymous

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

anonymous

Best ResponseYou've already chosen the best response.0a way to solve it is writing the equations of stickers collected by each of them

anonymous

Best ResponseYou've already chosen the best response.0being m = months, then Bradley: Stickers=23+4m Ryan: Stickers=9+6m

anonymous

Best ResponseYou've already chosen the best response.0it means BRadley has 23 stickers and owns 4more each month and Ryan has 9 stickers and owns 6 more each month

anonymous

Best ResponseYou've already chosen the best response.0it is the same as the previous, and you can just write y=23+4x y=9+6x you want to know x

anonymous

Best ResponseYou've already chosen the best response.0in this case, you don't want to know y

anonymous

Best ResponseYou've already chosen the best response.0either, you could substitute the options in the formulas and see if they give the same number

anonymous

Best ResponseYou've already chosen the best response.0Sure you know! Bradley: [number of stickers]=23+4x Ryan: [number of stickers]=9+6x

anonymous

Best ResponseYou've already chosen the best response.0if you call number of stickers as 'y' then you see that y MUST be the same in both equations

anonymous

Best ResponseYou've already chosen the best response.0and so the right hand sides of the equations

anonymous

Best ResponseYou've already chosen the best response.0so 23+4x=9+6x and you just need to find x

anonymous

Best ResponseYou've already chosen the best response.0but look at the system and you will see one is the same as the other

anonymous

Best ResponseYou've already chosen the best response.0one equation is the same as the other

anonymous

Best ResponseYou've already chosen the best response.0so you can't find just one value for (x,y) any x value gives an right y value

Best ResponseYou've already chosen the best response.0(71)/(25) or (17)/(52) You just need to use the correspondent positions to x's and y's values

anonymous
