Write the equation of the line that passes through (3,6) and is parallel to y = 2/3x+2.

aleksley [76]

Answer:

$y=\frac{2}{5}x-5$

Step-by-step explanation:

$y=\frac{2}{3}x+4$

the line parallel to this line is

$y=\frac{2}{3}x+k$ ; k ∈ R

the line passes through the point (3,6)

so,

$6=\frac{2}{3} (3)+k\\6=2 +k\\k=4$

∴the line that passes through point (2, -1) and is parallel to the line described y = (2/3)x - 6 is

$y=\frac{2}{3}x+4$

Using the quadratic formula to solve x2 = 5 - X, what are the values of X?

sdas [7]

Answer:

The answer is

<h3> $x = \frac{ - 1 + \sqrt{21} }{2} \: \: \: or \: \: \: x = \frac{ - 1 - \sqrt{21} }{2}$ </h3>

Step-by-step explanation:

x² + x - 5 = 0

Using the quadratic formula

That's

<h3> $x = \frac{ - b\pm \sqrt{ {b}^{2} - 4ac } }{2a}$ </h3>

From the question

a = 1 , b = 1 , c = - 5

Substitute the values into the above formula and solve

We have

<h3> $x = \frac{ - 1\pm \sqrt{ {1}^{2} - 4(1)( - 5) } }{2(1)} \\ x = \frac{ - 1\pm \sqrt{1 + 20 } }{2} \\ x = \frac{ - 1\pm \sqrt{21} }{2}$ </h3>

We have the final answer as

<h3> $x = \frac{ - 1 + \sqrt{21} }{2} \: \: \: or \: \: \: x = \frac{ - 1 - \sqrt{21} }{2}$ </h3>

Hope this helps you
