Answer:

4.16x+6y=1

Step-by-step explanation:

The given equation of the line is:

8x + 3y = 1

From this line, we need to re-arrange and write in the form of the equation of a straight line.

The equation of a straight line is given as:

y = mx + c

8x + 3y = 1

3y = -8x + 1

y = $\frac{-8x}{3}$ + $\frac{1}{3}$

The slope of the line is $\frac{-8}{3}$

Any line from the given choices that will be parallel to the is must have the same slope as it is.

That line is 16x + 6y = 1

6y = -16x + 1

y = $\frac{-16x}{6}$ + $\frac{1}{6}$

y = $\frac{-8x}{3}$ + $\frac{1}{6}$

If a polynomial function f(x) has roots 1+square root of 2 and-3, what must be a factor of f(x)?

nevsk [136]

To find the factor a a polynomial from its roots, we are going to seat each one of the roots equal to $x$ , and then we are going to factor backwards.

We know for our problem that one of the roots of our polynomial is -3, so lets set -3 equal to $x$ and factor backwards:
$x=-3$
$x+3=0$
$(x+3)$ is a factor of our polynomial.

We also know that another root of our polynomial is $1+ \sqrt{2}$ , so lets set $1+ \sqrt{2}$ equal to $x$ and factor backwards:
$x=1+ \sqrt{2}$
$x-1= \sqrt{2}$
$x-1- \sqrt{2}=0$
$(x-(1+ \sqrt{2})=0$
( $(x-(1+ \sqrt{2} ))$ is a factor of our polynomial.

We can conclude that there is no correct answer in your given choices.

What makes a pair linear?

zavuch27 [327]

Answer:

A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
