@jigglypuff314 idk what i did wrong lol

jigglypuff314 · Answer

hmm what did you put that you got wrong? .-.

elisaneedshelp · Answer

lol i put y=5/2x+1

jigglypuff314 · Answer

oh! I see
becareful
because the b = the y value when x = 0

the point they gave was for when x = -4
from (-4, 1) see?

elisaneedshelp · Answer

oh

elisaneedshelp · Answer

so what happens now I dont remember and the internet is confusing

jigglypuff314 · Answer

so we should Temporarily plug in the point for both x And y
to find our 'b'

1 = (5/2)*(-4) + b

elisaneedshelp · Answer

ok so b would be 11 and then it would be y= 5/2x+11 ?

jigglypuff314 · Answer

yep! that's what I go too :D

Two consecutive even integers have a sum of 50. Find the integers.

elisaneedshelp · Answer

I dont understand this at all.

jigglypuff314 · Answer

well two consecutive even integers would be
x and x+2 right?

where  x  is the first even number
and the next even number would be  x+2

elisaneedshelp · Answer

x would be 50?

elisaneedshelp · Answer

Can you walk me thru this one please? and there was this other one last night that even had like stuff with 3x +2 or something like that.

elisaneedshelp · Answer

jigglypuff314 · Answer

yep ^_^
so that's one of the numbers
the other number would be 24 + 2 :P

elisaneedshelp · Answer

Oh ok

elisaneedshelp · Answer

Three consecutive integers have a sum of 48. Find the integers. To find 3 for this one would be different? or like x+x+3=48 ?

jigglypuff314 · Answer

if the smallest number is x
the next consective integer is x+1
and the one after that is x+2
so  x + x + 1 + x + 2 = 48

elisaneedshelp · Answer

wow its so confusing but ok :P
