Goshia [24]

Answer:

Inverse of -5-9x/x-6

Step-by-step explanation:

Steps:

1: Interchange the variables x and y.

x=6y-5/y+9

2: Solve x = 6y-5/y+9 for y

3: Multiply both sides by y+9

4: Simplify and Expand

5: Subtract 9x from both sides.

6: Simplify and Subtract y from both sides then Simplify again

7: Divide both sides by x-6

Answer: Inverse of -5-9x/x-6

Order the following numbers from least to greatest.

Marianna [84]

Answer:

$\Huge \boxed{-2.3, \ \frac{-1}{3} , \ \sqrt{3} , \ \sqrt{7} , \ 5.1}$

$\rule[225]{225}{2}$

Step-by-step explanation:

We will convert the values into decimals for simplicity.

$\sqrt{7} = 2.64575131106...$

$-2.3=-2.3$

$\sqrt{3} = 1.73205080757...$

$5.1=5.1$

$\displaystyle \frac{-1}{3} =-0.333333333...$

Arranging from least to greatest:

$\displaystyle -2.3, \ \frac{-1}{3} , \ \sqrt{3} , \ \sqrt{7} , \ 5.1$

$\rule[225]{225}{2}$
