What is Perpendicular to 5x-3y=30 and passing through (-2,7)

alisha [4.7K]

$k:y=m_1x+b_1;\ l:y=m_2x+b_2\\\\k\ \perp\ l\iff m_1\cdot m_2=-1\\\\k\ ||\ l\iff m_1=m_2$

We have:

$k:5x-3y=30\ \ \ \ |-5x\\\\-3y=-5x+30\ \ \ \ |:(-3)\\\\y=\dfrac{5}{3}x-10\to m_1=\dfrac{5}{3}\\\\l:y=m_2x+b\\\\k\ \perp l\Rightarrow \dfrac{5}{3}m_2=-1\ \ \ \ |\cdot\dfrac{3}{5}\\\\m_2=-\dfrac{3}{5}$

$l:y=-\dfrac{3}{5}x+b$

The line l is passing through (-2, 7). Substitute the coordinates of the point to the equation of a line l:

$7=-\dfrac{3}{5}\cdot(-2)+b\\\\\dfrac{6}{5}+b=7\ \ \ \ |-\dfrac{6}{5}\\\\b=\dfrac{35}{5}-\dfrac{6}{5}\\\\b=\dfrac{29}{5}$

$l:y=-\dfrac{3}{5}x+\dfrac{29}{5}\ \ \ \ |\cdot5\\\\5y=-3x+29\ \ \ \ |+3x\\\\3x+5y=29$

<h2>Answer: 3x + 5y = 29</h2>

translate the following sentence into an equation. the sum of twice a number x and 13 is two less than three times x

sergiy2304 [10]

I’m pretty sure the equation would be

2x + 13 < 3x - 2

ivanzaharov [21]

Using the distributive property, you’ll get the equation 56i+63.

You’ll distribute (multiply) 7 to 8i, and 7 to 9

T-6=8-t<br><br>how do solve? pls include steps

umka2103 [35]

First, add t to each side:
2t - 6 = 8
Add 6 to each side:
2t = 14
Divide both sides by 2:
t = 7

Hope this helps!! :)
