Answer:

y - 10 = 2(x - 4)

Step-by-step explanation:

Recall this:  The slope of a new line perpendicular to a given line is the negative reciprocal of the slope of the given line.

Thus:  The slope of the new line is the negative reciprocal of (-1/2), or +2.

Using the point-slope formula for the equation of a line,

y - k = m(x - h)

becomes

y - 10 = 2(x - 4)

This could also be written as y = 2x - 8 + 10, or y = 2x + 2

Find each Of change. Round to the nearest whole percent if necessary. State whether the percent Of change is an increase or 1. O
Alenkasestr [34]

Answer:

1. The percentage change is 74% and it is a percentage decrease

2. The percentage change is 15% and it is a percentage decrease

3. The percentage change is 20% and it is a percentage decrease

4. The percentage change is 43% and it is a percentage increase

5. The percentage change is 40% and it is a percentage decrease

6. The percentage change is 39% and it is a percentage decrease

Step-by-step explanation:

Given

1.\ Original = 5; New = 1.3

2.\ Original = 160; New = 136

3.\ Original = 15; New = 12

4.\ Original = 7; New = 10

5.\ Original = $30; New = $18

6.\ Original = 9.6; New = 5.9

Required

Determine the percentage change and state whether it's an increase or decrease

Percentage change is calculated as:

\%Change = \frac{New - Original}{Original} * 100\%

1.\ Original = 5; New = 1.3

\%Change = \frac{1.3 - 5}{1.3} * 100\%

\%Change = \frac{-3.7}5} * 100\%

\%Change = \frac{-3.7 * 100\%}{5}

\%Change = \frac{-370\%}{5}

\%Change = -74\%

<em>The percentage change is 74% and it is a percentage decrease</em>

2.\ Original = 160; New = 136

\%Change = \frac{136 - 160}{160} * 100\%

\%Change = \frac{-24}{160} * 100\%

\%Change = \frac{-24 * 100\%}{160}

\%Change = \frac{-2400\%}{160}

\%Change = -15\%

<em>The percentage change is 15% and it is a percentage decrease</em>

3.\ Original = 15; New = 12

\%Change = \frac{12- 15}{15} * 100\%

\%Change = \frac{-3}{15} * 100\%

\%Change = \frac{-3* 100\%}{15}

\%Change = \frac{-300\%}{15}

\%Change = -20\%

<em>The percentage change is 20% and it is a percentage decrease</em>

4.\ Original = 7; New = 10

\%Change = \frac{10- 7}{7} * 100\%

\%Change = \frac{3}{7} * 100\%

\%Change = \frac{3* 100\%}{7}

\%Change = \frac{300\%}{7}

\%Change = 43\% -- (approximated)

<em>The percentage change is 43% and it is a percentage increase</em>

<em></em>

5.\ Original = $30; New = $18

\%Change = \frac{18- 30}{30} * 100\%

\%Change = \frac{-12}{30} * 100\%

\%Change = \frac{-12* 100\%}{30}

\%Change = \frac{-1200\%}{30}

\%Change = -40\%}

<em>The percentage change is 40% and it is a percentage decrease</em>

6.\ Original = 9.6; New = 5.9

\%Change = \frac{5.9- 9.6}{9.6} * 100\%

\%Change = \frac{-3.7}{9.6} * 100\%

\%Change = \frac{-3.7* 100\%}{9.6}

\%Change = \frac{-370\%}{9.6}

\%Change = -39\% -- (approximated)

<em>The percentage change is 39% and it is a percentage decrease</em>
