Question

Complete the standard form of the equation y=10-5/2 x

Answer 1

well standard form has a definition to it. can you tell me what standard form is?

Answer 2

in your material, standard form should look like:

ax + by = c

notice that we have both x and y parts on one side .... what should we do to work this?

Answer 3

kind of, we can subtract -5/2 x from each side, but this can also be called addition ... add 5/2 x to each side

Answer 4

y = 10 - 5/2 x
+5/2x +5/2 x
------------------
5/2 x + y = 10

almost there ....

Answer 5

we want all integer values in this, not fraction or decimals ... so we need to make 5/2 into just a 5

any thoughts on how to do this?

Answer 6

well, multiplyng everything by 2 should work for us

2 (5/2 x + y = 10)

5*2/2 x + 2y = 2(10)

since 2/2 = 1 ...

5x + 2y = 20

now we need to make sure the leading x term is positive ... in this case it is so we are fine

Answer 7

yeah, you editing out the content of your posts does not constitute me breaking the rules ... good luck with that tho

Answer 8

See, mods can see deleted posts, so what you did by "deleting" basically means nothing to a mod.
