8 0

Answer:

3x + 2

Step-by-step explanation:

6x + 1 - (3x-1) < distribute the negative sign into the expression

6x + 1 -3x + 1 < combine like terms

6x - 3x = 3x

1 + 1 = 2

our simplified expression is:

3x + 2

What is the slope of the line that passes thru (7,2) and (9,6)?
Leya [2.2K]
Hey there Hopire :)
To solve this, we'll use the slope given two points formula. Here it is:

y2-y1/x2-x1

Plug in the values.

6-2/9-7 =

4/2 =

2

Therefore, the slope is two, meaning 2/1 because slope is rise/run. That means that for every two you go up, you go one to the right because it's a positive slope- left for negatives.

Hope this helped!

What’s the answer???(ONLY ANSWER IF YOU KNOW PLEASE)
Vlad1618 [11]

Answer: B

<u>Step-by-step explanation:</u>

(a + b)³ = (a + b)(a² - ab + b²)

(\sqrt{2x} + \frac{1}{x})^{3} = (\sqrt{2x} + \frac{1}{x})(\sqrt{2x}^{2} - \sqrt{2x}(\frac{1}{x}) +(\frac{1}{x})^{2})

= (\sqrt{2x} + \frac{1}{x})(2x - \frac{\sqrt{2x}}{x} +\frac{1}{x^{2}})

= (\sqrt{2x}(2x - (\frac{\sqrt{2x}}{x}) +\frac{1}{x^{2}}) + \frac{1}{x}(2x -\frac{\sqrt{2x}}{x} +\frac{1}{x^{2}})

= 2x\sqrt{2x} - 2 +\frac{\sqrt{2x} }{x^{2}} + 2 - \frac{\sqrt{2x}} {x^{2}} + \frac{1}{x^{3} }

= 2x\sqrt{2x}+\frac{1}{x^{3} }
