Answer:

B is the answer

Step-by-step explanation:

So common sense again

C and D are automatically out since they don’t equal

A and B are left

B’s slope is more accurate but it’s just not simplified, its still 2/3

so the slope is 2/3 and they are on the ame slope so we already know they equal so B is the correct answer.

What is x2 – 6 = 16x + 30 rewritten in standard form, then factored?

AlexFokin [52]

Answer:

The standard form of quadratic equation is $x^2-16x-36=0$

The factored form of $x^2-16x-36=0$ is $(x+2)(x-18)=0$

Step-by-step explanation:

Given equation $x^2-6=16x+30$

We have to write in standard form and then factorize the given equation.

The standard form for a general quadratic equation is given as $ax^2+bx+c=0$

Consider $x^2-6=16x+30$

Taking all terms to left side, we have,

$x^2-6-16x-30=0$

Adding like terms, we have,

$x^2-16x-36=0$

Now we will factorize it.

We will solve the quadratic equation $x^2-16x-36=0$ using middle term splitting method,

-16x can be written as -18x+2x

$x^2-16x-36=0$ becomes

$\Rightarrow x^2-18x+2x-36=0$

Taking x common from first two terms and 2 common from last two terms we have,

$\Rightarrow x(x-18)+2(x-18)=0$

$\Rightarrow (x+2)(x-18)=0$

Thus, the factored form of $x^2-16x-36=0$ is $(x+2)(x-18)=0$

If the coefficient of correlation is .8, then the percentage of variation in the dependent variable explained by the estimated r

Olegator [25]

Answer:

64%

Step-by-step explanation:

The percentage of variation in the dependent variable explained by the estimated regression is calculated with the coefficient of correlation as follows:

First, square the coefficient of correlation: 0.8^2 = 0.64

And then, multiply this result by 100, so that, it is expressed as a percentage: 0.64*100 = 64%
