X = y + 12. You then substitute or plug in that from the first equation into the second equation. You get (y+12)+y=18, then you simplify to get your y value. In this case y = 3. The you can plug your y value into either equation. (x+3=18) or (x-3=12) or (x=3+12) either way you get x=15 and y=3.
This is considered a function because each input has a different output. For example, a certain x value doesnt equal 2 different y values, making this a function. Take this: if there is (2,4) and (3,4), this is a function because although the y values are the same, the x values are different. (2,3) and (2,4) do not convey a function because the x values are the same, but each has a different y value.
hope this helped!!!
brainliest answer, please?
C is same thing as 1c
1c + 1/4c
(In simple words: Adding a whole to 1/4.)
1 + 1/4 = 1 1/4 or 5/4
same thing when having c:
1c + 1/4c = 1 1/4c or 5/4 c
Answer: 1 1/4c or 5/4c
Easily option #1. Time is money in this world. first option benefits you short term and long term. There would be no reason as why you’d want option #2
2x+4=3x+2
2x=3x-2
-1x=-2
X=2
Hope this helps!
