The amount of paper recycled is directly proportional to the number of trees that recycling saves. If recycling 2,000 pounds of

paper saves 17 trees, how many trees are saved when 5,000 pounds of paper are recycled?

Find an equation to the line perpendicular to 4x + 36y =80 an goes through the point (3,6) write answer in form y= Mx+b

Veronika [31]

Answer:

$\textbf{y = 9x + 21 }\\$

Step-by-step explanation:

$\textup{Given equation is: $4x + 36y = 80 $}\\\textup{This can be written in the form of $y = mx + a$ as follows}\\$ 36y = -4x + 80 $\\$ \implies y = \frac{80}{36} - \frac{4}{36}x $\\$ \implies y = \frac{-1}{9}x + \frac{20}{9} $\\\textup{This means that the slope of this line is $m = \frac{-1}{9}$}\\$

$\textup{Then the slope of the line perpendicular to this line would be \textbf{negative reciprocal of m}.}\\$i.e.,$ \textup{Slope of the perpendicular line would be $m_1 = \frac{-1}{\frac{-1}{9}}$}\\$\implies m_1 = 9$\\$

$\textup{The perpendicular line passes through the point $(3,6)$}\\\textup{Using the \textbf{point-slope formula}, we get:}\\$

$$$ y - y_1 = m(x - x_1) $$$ \implies y - 6 = 9(x - 3) $\\\textup{After solving this reduces to $y = 9x + 21$ }$

9- 4(2p+3) - 8p+7<br> how do i solve this ?

Sholpan [36]

Answer:

$= -16p+4$

Step-by-step explanation:

First we simplify:

$9-4(2p+3)-8p+7$

Then we distribute:

$=9+(-4)(2p)+(-4)(3)+(-8p)+7\\=9+(-8p)+(-12)+(-8p)+7$

Lastly, combine like terms:

$=9+-8p+-12+-8p+7\\=(-8p+-8p)+(9+-12+7)\\=-16p+4$

Hope this helps!

Have a good evening! :)
