180 - 149 = 31
x/100 *149 = 31
1.49x = 31
x= 31/1.46 = 20.81 %
16/5 is roughly equal to 3.2. Is that what your are asking?
-12y+14-9y=14
-21y=0
y=0, x=7
Y - y1 = m(x - x1)
slope(m) = -4/3
(0,-12)....x1 = 0 and y1 = -12
sub
y - (-12) = -4/3(x - 0) =
y + 12 = -4/3(x - 0) <=== point slope form
y + 12 = -4/3x
y = -4/3x - 12 <=== slope intercept form
y = -4/3x - 12
4/3x + y = -12
4x + 3y = -36 <=== standard form
