-9x - 10 = 62 -9x = 72 x = -8
The slope intercept form is: y = mx + b 9x + 7y = 15 9x - 9x + 7y = 15 - 9x 7y = - 9x + 15 y = -(9/7)x + 15/7
If f(x)=(5x-1)/9 Then the inverse is x=(5y-1)/9 9x=5y-1 9x+1=5y (9x+1)/5=y The inverse is f(x)=(9x+1)/5
9x is the lowest common multiple. (9x * 1 = 9x) (x * 9 = 9x)
32-9x=140 9x=108 x=12
(9x)2 +9x/(45x)2 +81= 9+9x/86
9x - 8 = 46 9x = 46 +8 9x= 54 9x/9 = 54/9 x= 6
9x+6=51 9x = 45 x= 5 9x-6=51 9x = 57 x= 6.33
9x = 30
9x+27 = -81 9x = -81-27 9x = -108 x = -12
The inverse of an equation is rewriting it as a function of the other variable. Simply solve the equation for x instead of y. y=9x can be written as x= (1/9)y --> fy=y/9◄ y=4x+6 (or 4x+6=y) -> 4x=y-6 -> x=(y-6)/4 --> gy=(y-6)/4■
2y - 9x = 14 2y = 14 + 9x y = (14 + 9x) / 2
-9x-25=3 -9x=28 9x=-28 x=-28/9
9x+18 = 180 9x = 180-18 9x = 162 x = 18
