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 $y = 9x + 21$ }$

Trevor took one of his friends out to lunch. The lunches cost $248.40 and he paid 12.5% sales tax. If Trevor left a 15% tip on t

bixtya [17]

He paid ...

-- The cost of the lunches (100% = 1.00 of it)

-- 15% of the cost as a tip (15% = 0.15 of it)

-- 12% of the cost as sales tax (12% = 0.12 of it)

Total that he paid = (1.00 + 0.15 + 0.12) = 1.27 of $248.40

= $315.47 .

Trevor is one generous guy !

If you have 3x + y = 9 write it in slope intercept form... what is the slope, y intercept?

ladessa [460]

Step-by-step explanation:

given

3x + y = 9

Writing In slope intercept form , y = mx + c

y = -3x + 9

comparing the given equation with y = mx + c

slope (m) = - 3

y-intercept (c) = 9

Hope it will help :)
