It is +4x
8x-5=23+4x 8x-5-4x=23+4x-4x 4x-5=23 4x-5+5=23+5 4x=28 4x/4=28/4 x=7
To find the inverse, replace y with x, and x with y. So, the inverse of the equation is: x = 4yWhich is equal to:y = x/4
for variables x and y and constanat k -
4x+5 = -9 4x = -9-5 4x = -14 x = -3.5

The inverse for f(x) = 4x + 8 isg(x) = x/4 - 2
if f(x) = 4x, then the inverse function g(x) = x/4
8x-5=23+4x 8x-5-4x=23+4x-4x 4x-5=23 4x-5+5=23+5 4x=28 4x/4=28/4 x=7
16x2 - 25 = (4x + 5) ( 4x - 5)
The inverse for f(x) = 4x + 8 isg(x) = x/4 - 2
To find the inverse, replace y with x, and x with y. So, the inverse of the equation is: x = 4yWhich is equal to:y = x/4
16x2 - 25 = (4x + 5) (4x - 5)
16x2 + 40x + 25 = 16x2 + 20x + 20x + 25 = 4x(4x + 5) + 5(4x + 5) = (4x + 5)(4x + 5) = (4x + 5)2
The additive inverse for a number is its negative value. The sum of an integer and its additive inverse is zero. For the example (5), the additive inverse would be (-5).
