How would I graph these after solving d.
like mx+y=b
d=mj+b
a+b=6 solve for a:=b+6
25a+50b=200 solve for a:=2525b/50

Best ResponseYou've already chosen the best response.0I had to : 1. explain a situation/ situation. 2. Choose some variables and what each represents. 3. How I would set it up and solve algebraically. 4. Graph it

Best ResponseYou've already chosen the best response.1Let the variable j be placed along the x axis and the variable d be placed along the y axis dw:1440636598500:dw we can't have a negative number of either jeans or dresses so we only focus on quadrant 1

Best ResponseYou've already chosen the best response.1for d=j+6 you should find that when j = 0, d = 6 so (0,6) lies on the graph of d = j+6 dw:1440636692866:dw

Best ResponseYou've already chosen the best response.1also, when d = 0 is plugged into d=j+6, you'll find that j = 6 the ordered pair (6,0) lies on the graph of d=j+6 as well dw:1440636769380:dw

Best ResponseYou've already chosen the best response.1now onto the second equation if j = 0, then what is the value of d in d = 1/2j + 4 ?

Best ResponseYou've already chosen the best response.1so (0,4) lies on the graph of d = 1/2j + 4 dw:1440636989180:dw

Best ResponseYou've already chosen the best response.1now if d = 0 in d = 1/2j + 4, what is the value of j ?

Best ResponseYou've already chosen the best response.1if you plugged in j = 4 you would get d = 1/2j + 4 d = 1/2*4 + 4 d = 2 + 4 d = 2 which is not 0 like we want

Best ResponseYou've already chosen the best response.1same with j = 2 if you plugged in j = 2 you would get d = 1/2j + 4 d = 1/2*2 + 4 d = 1 + 4 d = 3 which is not 0 like we want

Best ResponseYou've already chosen the best response.1d = 1/2j + 4 0 = 1/2j + 4 4 = 1/2j 1/2j = 4 j = 4*(2) j = 8 so basically when j = 8, the value of d is d = 0 meaning we have the point (8,0) on the graph of d = 1/2j + 4 dw:1440637317827:dw
