1.20x+2.50y=300 List 3 possible combinations.

Question

agreene · Answer

Solve for y=STUFF and then plug values in for x and get your y values which gives you pairs. Also, didn't you already ask this question?

anonymous · Answer

Write them as coordinates or something like that

agreene · Answer

yes, you should probably right them as coordinates.

anonymous · Answer

Do what agreene said: choose a value for either x or y and then solve for the other variable.

I will write it in standard form first

12x + 25y = 3000

Now I will write it in another form:$$y = -\frac{12}{25}x+120$$

I can now select points for x, and evaluate y.

(0,120), (1,119.52),(2,119.04)

anonymous · Answer

wouldnt a coordinate be 250,0

agreene · Answer

Yes (250,0)  is contained by that function.

anonymous · Answer

I got (120,0) (250,0) and I can't figure out the last one

agreene · Answer

(120,0) is not a valid answer.  Please look at what I said to start this, and what agdgdgdgwngo was gracious enough to solve for you.

anonymous · Answer

I mean 0,120

anonymous · Answer

Okay sorry

agreene · Answer

(0,120)  yes, that is valid. As is (pi,120-12pi/25)
