Answer:

4. y = 1/2x + 3/2

Step-by-step explanation:

First, we need to change the line that's parallel into slope-intercept form.

-2x + 4y = 8

4y = 2x + 8

y = 1/2x + 2

If it's parallel, then it remains the same. So our slope is 1/2.

To find the y-intercept, you need to plug the coordinates into the equation.

y = 1/2x + b

-1 = 1/2(-5) + b

-1 = -5/2 + b

3/2 = b

y = 1/2x + 3/2

Answer:

Step-by-step explanation:

Each term in the second factor is multiplied by each term in the first factor, that is

y(y² + 4y + 16) - 4x(y² + 4y + 16) ← distribute both parenthesis

= y³ + 4y² + 16y - 4xy² - 16xy - 64x

Compare - axy to - 16xy ⇒ a = 16

Answer: Choice B

$\left\{ \ 3, 5, \sqrt{34} \ \right\}$

=========================================================

Explanation:

We'll be using the converse of the pythagorean theorem.

If we had a triangle with sides a,b,c and $a^2+b^2 = c^2$ was true, then we have a right triangle. Note: c is always the longest side

For the first answer choice we have: a = 5, b = 8, c = 12

Then,

$a^2+b^2 = c^2\\\\5^2+8^2 = 12^2\\\\25+64 = 144\\\\89 = 144\\\\$

which is false. This shows that we do not have a right triangle with sides 5,8,12. This rules out choice A. Choice C is a similar story.

Choice B on the other hand works because

$a^2+b^2 = c^2\\\\3^2+5^2 = (\sqrt{34})^2\\\\9+25 = 34\\\\34 = 34\\\\$

We have a true statement at the end, which confirms choice B is a right triangle.
