An equation is quadratic if the greatest power of the coefficients is 2. Hence, for the given equations, only 6(2x + 4)2 = (2x + 4) + 2 is quadratic in nature.

Match each pair of points to the equation of the line that is parallel to the line passing through the points.
Tanya [424]
If we identify the lines by ...
  1. y = -0.5x -3
  2. y = -3.5x -15
  3. y = 5x +19
  4. y = 1.25x +4

Then the matches are ...
  BC - 2
  DE - 1
  FG - none
  HI - 4
  JK - none
  LM - 3

_____
Whenever there is a lot of repetitive math to do, I usually find it easier to let a calculator or spreadsheet do it. Here, the graphing calculator is computing the slope between the points. The slopes of parallel lines are the same.

What is the length of the unknown side of the right triangle?
DerKrebs [107]

Answer:

13

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean Theorem

a^2+b^2=c^2

where<em> a</em> and <em>b</em> are the legs and <em>c</em> is the hypotenuse.

We know that the legs are 5 and 12. We also know the hypotenuse is x, or unknown.

Substitute 5 in for <em>a</em>, 12 for <em>b, </em>and x for <em>c.</em>

<em />5^2+12^2=x^2<em />

Evaluate the exponents.

5^2 is the same as 5*5, which is 25.

12^2 is the same as 12*12, which is 144.

25+144=x^2

Add 25 and 144

169=x^2

We are trying to find out what <em>x</em> is. In order to do this, we have to get <em>x</em> alone. Since x is being squared, take the square root of both sides. The exponent and square root will cancel, leaving x by itself.

\sqrt{169} =\sqrt{x^2} \\\\\sqrt{169}=x\\13=x

The hypotenuse is 13.
