What is the inverse of the function f(x) = x + 2?
nadya68 [22]

Answer: h(x)=x-2

Step-by-step explanation:

To find the inverse of the function f(x) = x + 2, the first  step is to replace f(x) with "y":

 f(x) =y= x + 2\\\\ y = x + 2

The second step is to solve for the variable "x":

x=y-2

The third step is to interchange the variables, then:

y=x-2

Finally, let be h(x) the inverse of the function f(x). Then, you can replace "y" with h(x). Therefore, this is:

h(x)=x-2

For #7, one line should have the y-intercept of -2 and a slope of 2/3 and the other line's y-intercept is 1 and its slope should be -5.

In the image provided, the red line represents 2/3x - 2 and the blue line represents -5x + 1.


8) Organize the information you are given.

*Savannah is 24 years older than Ryan.

So, Ryan's age + 24 = Savannah's age.

*Sebastian is 5 times as old as Ryan.
So, Ryan's age × 5 = Sebastian's age.

*Savannah and Sebastian are twins. They have the same age.
So, Savannah's age = Sebastian's age

Let x represent Ryan's age.

Write the equation based on the information you are given.

x + 24 = x(5)

x + 24 = 5x

Solution: D) 24 + x = 5x

I need help on writing fractions into simplest form
mojhsa [17]
Hi!

Is there a specific question you need help with? Writing fractions into simplest form is very easy. All you have to do is find a number that both the numerator and denominator can be divided by, and divide them both with it.

For example: 15/20. They both can be divided by 5. So do that. 15 divided by 5 = 3. 20 divided by 5 = 4. So the new fraction will be 3/4. It cannot be divided by another whole number. So that is the simplest form.

Pls let me know if you need more help.

Have a great day!
