Help! It says that I need to determine If both equations represent lines which are parallel, perpendicular, or none...

12345 [234]

  4x + 2y = 8   (1)
  8x + 4y = -4y (2)

A) Two lines are parallel if they have the same gradient
- putting both equations into the gradient- intercept form ( y = mx + c where m is the gradient)
(1) 4x + 2y = 8
  2y = 8 - 4x
y = -2x + 4

  (2) 8x + 4y = -4y
  <span>   </span>8x = -4y - 4y
y = $\frac{-8x}{-8}$
y = -x
<span>Thus the gradient of the two equations are different and as such    the two lines are not parallel
</span>
B) When two lines are perpendicular, the product of their gradient is -1
$m_{1} * m_{2} = p$
p = (-2) * (-1)
p = 2
<span>   ∴ the two lines are not perpendicular either.</span>

Thus these lines are SKEWED LINES

Your friend claims that when a polynomial function has a leading coeffcient of 1 and the coefficients are all integers , every p

sammy [17]

Using the rational root theorem, it is found that your friend is correct.

<h3>What is the rational root theorem?</h3>

It is a theorem that states that for a polynomial with integer coefficients, with q being the factors of the leading coefficient and p being the factors of the constant, every <u>possible rational root</u> is the format $\frac{p}{q}$ .

In this problem:

The leading coefficient is 1, hence it's only factor is $q = 1$ , thus guaranteeing that every possible rational zero is an integer, which means that your friend is correct.
