Which one is the answer? Answer these two
kirill [66]

Answer

Expressions 4(x+5) and 5(x+4) are Equivalent

Expressions 5(2m+2) and 10m+10 are not equivalent

Step-by-step explanation:

Heres why,

4(x+5) and 5(x+4)

4 times x =4x, so multiply 4x by 5 which should give you 20.

and multiply 5 to x which would be 5x and multiply that to 4 which would be 20, they match up so they are Equivalent.

5(2m+2) and 10m+10

times 5 to 2m to get 10m and times 10m by 2 to get 20.

10m+10 = 1 which they are not equivalent

Write the inverse function for the function, ƒ(x) = x + 4. Then, find the value of ƒ -1(4). Type your answers in the box.
lesya [120]

The inverse is:

f^{-1}(x) = x-4

Further explanation:

Given function

f(x) = x+4

<u>Step 1: Replacing f(x) with y</u>

y = x+4

<u>Step 2: Replacing x with y and y with x</u>

x = y+4

<u>Step 3: Solving the equation for y</u>

x = y +4\\x -4 = y+4-4\\y = x-4

<u>Step 4: Replacing y with f-1(x)</u>

f^{-1}(x) = x-4

So, the inverse is:

f^{-1}(x) = x-4
