$\frac{7x+42}{x^2+13x+42}= \frac{7(x+6)}{x^2+7x+6x+42}= \frac{7(x+6)}{x(x+7)+6(x+7)}= \frac{7(x+6)}{(x+6)(x+7)}= \frac{7}{x+7}$

I WILL MARK BRAINLIST!!

Answer:

For $(2x^2 + 8x - 8)$ , the group is CLOSED as it a polynomial.

Step-by-step explanation:

Here, the given polynomials are:

$P(x)=(5x^2+2x-6)\\Q(x)=(3x^2-6x+2)$

Now, a group G is said to be <u>CLOSED UNDER SUBTRACTION</u> if,

a and b are he elements of G ⇒ (a-b) is ALSO AN ELEMENT of G

Now, here:

$R(x) = P(x) - Q(x) = (5x^2+2x-6) - (3x^2-6x+2) = (2x^2 + 8x - 8)$

or, $R(x) = (2x^2 + 8x - 8)$

Also, R(x) is a POLYNOMIAL.

So, R(x) is an Element of group G.

So, the set G of polynomials.

Hence, for the polynomial $(2x^2 + 8x - 8)$ , it will be a polynomial the group is CLOSED.

stiks02 [169]

Answer:

-23, $y=6x-23$

Step-by-step explanation:

We need slope intercept form but do not have the needed information. We will gather this information by using point slope form. The point-slope formula is $y -y_{1} =m(x -x_{1})$ where we substitute a point (x,y) for $(x_{1},y_{1})$ .

We have slope represented as m=6 and (3, -5). We input m and $x_{1} =3\\y_{1}=-5$ .

$y-(-5)=6(x-3)\\y+5=6(x-3)$

We now simplify the parenthesis and solve for y to have slope intercept form.

$y+5=6(x-3)\\y+5=6x-18\\y+5-5=6x-18-5\\y=6x-23$

The y-intercept is b of slope intercept form y=mx+b. Here b=-23.
