Answer:

41/25 or 1  16/25

Step-by-step explanation:

1 + 2/5 x 4/5 ÷ 1/2

do multiplication first

2/5 x 4/5 = 8/15

1 + 8/25 ÷ 1 /2

do division by multiplying by the reciprocal

1 + 8/25 x 2/1

1 + 16/25 = 1  16/25

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>

1/4 divided by 2 = ??
Iteru [2.4K]

Answer:

1/8

Step-by-step explanation:

Hi there!

To divided fractions, you must flip the second fraction and multiply instead.

For example,

1/4 divided by 2 is the same thing as 1/4 x 1/2.

You then multiple straight across to get 1/8.

Really hope this helps!
