The distance between two points on a number line can be found by taking the _[blank 1]_ of the _[blank 2]_ of the coordinates.

30 determine the coefficient on x 12 y 24 x12y24 in ( x 3 + 2 x y 2 + y + 3 ) 18 . (x3+2xy2+y+3)18. (be careful, as x x and y y now appear in multiple terms! )

How do you use the elimination method for this question? explain, because i really want to understand!

If a || b and e || f , what if the value of y ?
