What is equivalent to -1/4y -2 1/4y + 1/2 (4-2y)

yan [13]

Answer:

$14y - 8 = 0$

Step-by-step explanation:

$- \frac{1}{4} y - 2 \frac{1}{4} y + \frac{1}{2} (4 - 2y) = 0 \\$

$- \frac{1}{4} y - \frac{9}{4} y + 2 - y = 0$

$( - \frac{1}{4} y - \frac{9}{4} y + 2 - y = 0)4$

$- y - 9y + 8 - 4y = 0$

$- y - 9y - 4y + 8 = 0$

$- 14y + 8 = 0$

$14y - 8 = 0$

If f(x) = 3x + 3, then f-1(x) =

tensa zangetsu [6.8K]

Mathematically, when you calculate the inverse function (f-1(x)), you’re switching the “inputs” (x) and the “outputs” (f(x)) and then re-solving the equation. So, you’d start with something like:

x = 3*f-1(x) + 3
x - 3 = 3*f-1(x)
(x - 3)/3 = f-1(x)

Your inverse formula would be (x - 3)/3. Hope this helps! (Hopefully Brainly doesn’t mess up the text format.)
