What is the inverse of f(x)=4x+3 ?
GaryK [48]
<h2>Steps:</h2>

Here are the steps to convert an equation to its inverse:

  1. Change f(x) to y
  2. Switch the positions of x and y
  3. Solve for y
  4. Change y to f^-1(x)

Firstly, do the first two steps:

x=4y+3

Next, let's solve for y. Subtract 3 on both sides:

x-3=4y

Next, divide both sides by 4:

\frac{1}{4}x-\frac{3}{4}=y

<h2>Answer:</h2>

Finally, change y to f^-1(x) and your final answer will be:

f^{-1}(x)=\frac{1}{4}x-\frac{3}{4} , or <u>the second option.</u>

The diagonal of a square is 8 cm.
VladimirAG [237]

the length of the side of this square is 4\sqrt{2} \:or \:5.65cm

Answer:

Solutions Given:

let diagonal of square be AC: 8 cm

let each side be a.

As diagonal bisect square.

let it forms right angled triangle ABC .

Where diagonal AC is hypotenuse and a is their opposite side and base.

By using Pythagoras law

hypotenuse ²=opposite side²+base side²

8²=a²+a²

64=2a²

a²=\frac{64}{2}

a²=32

doing square root on both side

\sqrt{a²}=\sqrt{32}

a=±\sqrt{2*2*2*2*2}

a=±2*2\sqrt{2}

Since side of square is always positive so

a=4\sqrt{2} or 5.65 cm
