Replace n with 12.

9 + 12 / 3 - 6

Simplify.

21 / -3 = -7

Hope this helps!

Since n=12, you can just replace the n with 12 into the equation getting you (9+12)/(3-6) which equals to -7

Create a model of your choice to represent the

Hey there!

“6 + r = 8”

• FIRST: FIRST THE EQUATION

r + 6 = 8

• SECOND: SUBTRACT by 6 on BOTH SIDES

r + 6 – 6 = 8 – 6

CANCEL out; 6 – 6 because that gives you 0

KEEP: 8 – 6 because that helps solve for your r-value

• THIRD: SOLVE FOR YOUR EQUATION

8 – 6 = r

• FOURTH: ANSWER THE QUESTION

8 – 6 = 2

FIFTH: ANSWER

r = 2 ☑️

Good luck on your assignment and enjoy your day!

PLEASE HELP ASAP <br>are f(x)=4/x-2-1 and g(x)=3/x+2-2 inverses of each other?

GREYUIT [131]

Answer:

To find the inverse of:

$f (x)=\dfrac{4}{x-2}-1$

Set the function to y:

$\implies y=\dfrac{4}{x-2}-1$

Rearrange to make x the subject:

$\implies y+1=\dfrac{4}{x-2}$

$\implies (y+1)(x-2)=4$

$\implies xy-2y+x-2=4$

$\implies xy+x=2y+6$

$\implies x(y+1)=2y+6$

$\implies x=\dfrac{2y+6}{y+1}$

Swap x and y:

$\implies y=\dfrac{2x+6}{x+1}$

Change y to the inverse of the function sign:

$\implies f$ $\:^{-1}(x)=\dfrac{2x+6}{x+1}$

Rewrite g(x) as a fraction:

$g(x)=\dfrac{3}{x+2}-2$

$\implies g(x)=\dfrac{3}{x+2}-\dfrac{2(x+2)}{x+2}$

$\implies g(x)=\dfrac{3-2(x+2)}{x+2}$

$\implies g(x)=\dfrac{3-2x-4}{x+2}$

$\implies g(x)=-\dfrac{2x+1}{x+2}$

Therefore, as the inverse of f(x) ≠ g(x), the functions are NOT inverses of each other

Write a linear equation with slope -1 and y intercept of 3

MatroZZZ [7]

Answer:

y = -x +3

Step-by-step explanation:

Think about the Y= mx + b

m = -1 so it's -x

b = 3, so it's +3

y intercept goes after the slope:

Y= Mx + B

Y = -x + 3
