Answer:

2(2x^2 - x + 1)

Step-by-step explanation:

you write you problem 9x^2 - 2x - 5x^2 + 2 = 2(2x^2 - x + 1)

You collect the like terms by subtracting their coefficients

(9-5)x^2

Subtract the numbers

4x^2

4x^2 - 2x + 2

Factor out 2 from the expression

2(2x^2 - x + 1)

Evaluate log3^8, given log3^2 is equivalent to 0.631

elixir [45]

We will use the followin property of logarithms:

$log(a^b) = b log(a)$

So, we have

$log(3^2) = 2 log(3) = 0.631$

If you multiply both sides by 4, you get

$8log(3) = log(3^8) = 2.524$

What is the slope of (-4,6) and (2,-5)

Dominik [7]

Answer:

-11/6

Step-by-step explanation:

Slope can be found with this equation:

(y₁ - y₂) / (x₁ - x₂)

What this essentially tells us to do is to put one set of the x and y coordinates into x₁ and y₁, respectfully. Then, put the other set of x and y points as x₂ and y₂.

With this scenerio, we can substitute the given points into the formula.

(6 - (-5)) / (-4 - 2) =

(6 + 5 ) / (-6) =

11 / (-6) =

-11/6

The slope is - 11/6
