Answer:

<h2>x = 0 and y = -12</h2><h2>x = -6 and y = 0</h2><h2>x = 2 and y = -16</h2>

Step-by-step explanation:

Convert to the slope-intercept form:

<em>y = mx + b</em>

<em></em>

2x + y = -12        <em>subtract 2x from both sides</em>

y = -2x - 12

1. Take any value of <em>x</em>.

2. Put it to the equation.

3. Calculate the value of <em>y</em>.

Examples:

<em>for </em><em>x = 0</em>

<em>y = -2(0) - 12 = 0 - 12 = -12</em>

<em>for </em><em>x = -6</em>

<em>y = -2(-6) - 12 = 12 - 12 = 0</em>

<em>for </em><em>x = 2</em>

<em>y = -2(2) - 12 = -4 - 12 = -16</em>

<em>...</em>

What is the solution to the following system?
GalinKa [24]

Answer:

<em>(2, - 6, 3)</em><em> </em>

Step-by-step explanation:

2x - y - 3z = 1 ⇒ y = 2x - 3z - 1 .... <em>(1)</em>

4x + 3y + 2z = - 4 .... <em>(2)</em>

- 3x + 2y + 5z = - 3 .... <em>(3)</em>

(1) ---> (2) and (3)

4x + 3(2x - 3z - 1) + 2z = - 4 ⇔ 10x - 7z = - 1 ... <em>(4)</em>

- 3x + 2(2x - 3z - 1) + 5z = - 3 ⇔ x - z = - 1 ⇒ x = z - 1 ---> (4)

10(z - 1) - 7z = - 1 ⇒ <u><em>z = 3</em></u>

<u><em>x = 2</em></u>

2(2) - y - 3(3) = 1 ⇒ <u><em>y = - 6</em></u>

<em>(2, - 6, 3)</em>

What is the slop of a line perpendicular to the line whose equation is 4x+6y=108. Reduce your answer
ahrayia [7]

<u>Answer:</u>

The slope of a line perpendicular to the line whose equation is 4x+6y=108 is \frac{3}{2}

<u>Solution:</u>

Given, line equation is 4x + 6y = 108.

We have to find the slope of the line which is perpendicular to the given line equation.

We know that, <u><em>product of slopes of perpendicular lines equals to – 1</em></u>

So, now, let us find the slope of the given line equation.

\text { Slope of a line }=\frac{-x \text { coefficient }}{y \text { coefficient }}=\frac{-4}{6}=\frac{-2}{3}

Now,

slope of given line \times slope of its perpendicular line = -1

\frac{-2}{3} \times slope of perpendicular line = -1

\text { Slope of perpendicular line }=-1 \times \frac{3}{-2}=\frac{-3}{-2}=\frac{3}{2}

Hence, the slope of the perpendicular line is \frac{3}{2}
