i have no clue what the answer is
5*3y+1+12y-1 = 15y+1+12y-1 = 27y.
1
The slope is 1/3 and the y-intercept is -1.
Given: 15x - 20y = -1 15y = 2 + 5x Then: 15x -20(2 + 5x)/15 = -1 ∴15x -40/15 - 100x/15 = -15/15 ∴225x/15 - 100x/15 = 40/15 - 15/15 ∴125x = 25 ∴x = 1/5 Check: 15(1/5) - 20(1/5) = -1 ∴3 - 4 = -1 ∴-1 = -1
-1 plus 1 = 0 plus 1 =1
a+a=1 2a=1 a=1/2
x = 5, y = -1
That factors to (a + 1)(a + b) a = -1, -b b = -a
A = 1, B = 9
8+-1= 7 x=-1
If: x+1+2x = 1x+5 Then: x = 2
y=5
