If two functions are inverses of each other, which 2 statements are true?

Mathematics

galben [10]3 years ago

Answer:

A and B

Step-by-step explanation:

To be inverses, the inverse composite functions must equal x, since the input and output must be equal as how much you used as your input, which is x. B proves that. Also, the graph must reflect over y = x, which is the line that runs through the origin

(x + y + 2)(y + 1)<br> Solve
RideAnS [48]

Hello there! We are given the following equation and want to simplify it:

(x+y+2)(y+1)

First, let's use the Distributive Property:

  • (a+b)(c)=ac+bc

For this step, we are going to let:

  • a=y
  • b=1
  • c=(x+y+2)

After applying this version of the Distributive Property, we are given the equation:

(y)(x+y+2)+(1)(x+y+2)

We're going to use the distributive party again, but a slightly different version that's almost the same as first:

  • (a)(b+c+d)=ab+ac+ad

Using this on both terms of the equation changes the equation to:

(xy+y^2+2y)+(x+y+2)

Now, we just remove the parenthesis and combine like terms

y^2+3y+xy+x+2

This should be your answer. Let me know if you need any clarifications, thanks!

Okay, so keeping mind that the equation for area is A = L x W, look at the measurements you already have. 5.5 x 10^5 is the length, and 4.2 x 10^4 is the width. Switch them into full form and use a calculator to multiply the two for the area in meters.

550000 x 42000 = 23100000000, which in scientific form is 2.31 × 10^10. So that's answer one.

For the second, in kilometers, just take the full measurement you already have, 23100000000 m, transfer it into kilometers, 23100000 km, and then find its scientific notation, 2.31 × 10^7. That's answer two.

To answer the last question for which is more suitable, just consider what number you'd prefer to look at: a bigger number or a smaller one. Since the kilometer measurement number is smaller, its correct.

Summarily, the answers are 2.31 × 10^10, 2.31 × 10^7, and square kilometers, in that order.
