Answer: f(-6) = -\frac{12}{11}, f(-4) = \frac{4}{3}, f(6) = \frac{12}{11}

<u>Step-by-step explanation:</u>

#1 - 7 and 9 are correct but 8 is wrong:

f(x) = \frac{2x}{x^{2}-25}

f(-6) = \frac{2(-6)}{(-6)^{2}-25}

      = \frac{-12}{36-25}

      = \frac{-12}{11}

f(-4) = \frac{2(-4)}{(-4)^{2}-25}

      = \frac{-8}{16-25}

      = \frac{-12}{-9}

      = \frac{4}{3}

f(6) = \frac{2(6)}{(6)^{2}-25}

      = \frac{12}{36-25}

      = \frac{12}{11}

First, let's complete the angles in the triangle. Remember that the sum of the angles in a triangle is 180 degrees.

73 + 90 + x = 180

163 + x = 180

x = 17

So, the angle that completes the triangle is 17 degrees. If we look at that angle in the triangle and the one adjacent to it, we can see that those two angles form a linear pair (or are supplementary, both meaning that they add up to 180 degrees).

17 + x = 180

x = 163

So, 17's supplement is 163 degrees. The 163 degree angle corresponds with angle r, and corresponding angles are congruent.

Therefore, angle r is 163 degrees. The correct answer is option C.

Hope this helps!

What is the meaning of probability in math?

  • Probability is simply how likely something is to happen.
  • Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.
  • The analysis of events governed by probability is called statistics.

Three Types of Probability

  • Classical: (equally probable outcomes) Let S=sample space (set of all possible distinct outcomes).
  • Relative Frequency Definition
  • Subjective Probability.
