In your own words explain how you would solve this two step equation for the variable x. 9x-7=-7

NeX [460]

Answer:

Add 7 to both sides

Step-by-step explanation:

The equation has to be just x = y

There cannot be another number on the same side as the variable

Now that we did that, the equation is 9x = 0

x = 0

Well, that was easy lol

Answer:

$\frac{4x^3-3x^2+5x+6}{x+6}=4x^2-27x+167-\frac{996}{x+6}$

Step-by-step explanation:

The division problem given to us is $(4x^3-3x^2+5x+6)\div (x+6)$ .

To perform the synthetic division, we write out the coefficient of the polynomial. We set the linear factor to zero and solve for x, this becomes our divisor. That is $x+6=0\implies x=-6$ .

We carry out the synthetic division as shown in the attachment.

The result of the synthetic division is 4 -27 167 -996

The first three terms are the coefficients of the quotient and the last term is the remainder.

Therefore the quotient is $q(x)=4x^2-27x+167$ and the remainder is $r(x)=-996$ .

The dividend, the quotient and the divisor are written as

$\frac{4x^3-3x^2+5x+6}{x+6}=4x^2-27x+167-\frac{996}{x+6}$

The correct answer is A

The parent function f(x) = x^2 is vertically stretched by a scale factor of 2, translated 14 units right, and 6 units up. Which

Elena-2011 [213]

Answer:

$(1)\; G(x)=2(x-14)^2+6$

Step-by-step explanation:

Assuming, right and up are positive directions.

The given parent function, $f(x)=x^2$

Let $f_1(x)$ be the function when the parent function is stretched by a scale factor of 2.

So, $f_1(x)=2f(x)$

$\Rightarrow f_1(x)=2x^2$

Let $f_2(x)$ be the function when $f_1(x)$ is translated $14$ units right.

So, $f_2(x)=f_1(x-14)$

$\Rightarrow f_2(x)=2(x-14)^2$

Again, let $f_3(x)$ be the function when $f_2(x)$ is translated 4 units up.

So, $f_3(x)=f_2(x)+6$

$\Rightarrow f_3(x)=2(x-14)^2+6$

So, the resulting function, $f_3(x)=G(x)=2(x-14)^2+6$ .

Hence, option (1) is correct.
