Answer:

1. x = 5    2. y = 4      3. x = -2

Step-by-step explanation:

2x - y = 9             -5x + 2y = 13       3x + 4y = -6

<u>4x + y = 21</u>            <u>5x + y = -1   </u>      <u> 7x(-1) + 4y(-1) = -14(-1)</u>   <(multiply all by -1)

<u>6x = 30 </u>                      <u>3y = 12</u>       <u>  -4x = 8</u>

6       6                        3       3          4       4

x = 5                            y = 4              x = -2

Answer:

y = cot(x - ⅓π) + 2  

Step-by-step explanation:

The general equation for a cotangent function with the given properties is

y = Acot(Bx + C) + D, where

    A = the stretching factor

π/|B| = the period

    C = the phase shift (negative is to the right)

    D = the vertical shift

    A = 1

π/|B| = π, so1/|B| = 1 and B = 1

    C = -⅓π

    D = 2

The function is

y = cot(x - ⅓π) + 2

The figure below shows the graph of the function with the given parameters.

Note that the parent function y = cot(x) has the y-axis as an asymptote, so we can measure the phase shift by the movement of the asymptote π units to the right.

suppose that 23% of the people have a dog, 18% of the people have a cat and 5% of people own both. what is the probability that
mixer [17]
<h2>Addition</h2><h3>Concept</h3>

Add units together in order to reach a sum.

<h3>Utilization</h3>

In this problem, you are told to find the probability (or %) that someone owns either a dog, OR a cat. If they own both - then they do in fact own a dog or cat. So the formula is:

dog owners % + cat owners % + both owners %

Aka,

23 + 18 + 5 = 46

<h3>Answer</h3>

The answer is 46% of people own either a cat or a dog, because 23% + 18% + 5% is 46%.
