What is the slope of a line perpendicular to the line whose equation is 15x+18y=270. Fully simplify your answer.

In-s [12.5K]

Answer:

6/5

Step by step explanation:

Here we are provided with a equation which is ,

$\longrightarrow 15x + 18y = 270$

And we are interested in finding the slope of the line which is perpendicular to the given line. We may rewrite the equation as ,

$\longrightarrow 18y = -15x +270\\$

$\longrightarrow y =\dfrac{-15x+270}{18}\\$

$\longrightarrow y =\dfrac{-15}{18}x +\dfrac{270}{8}\\$

$\longrightarrow y =\dfrac{-5}{6}x +\dfrac{135}{4}$

Recall the slope intercept form of the line which is y = mx + c .On comparing to which we get ,

$\longrightarrow m =\dfrac{-5}{6}$

Again , recall that product of slopes of two perpendicular lines is -1. So that ,

$\longrightarrow m_{\perp} =-\bigg(\dfrac{1}{m}\bigg)$

Hence ,

$\longrightarrow\underline{\underline{ m_{\perp}= \dfrac{6}{5}}}$

And we are done !

A new lawn has a perimeter of 278ft. And a width of 64ft. A bag of grass seed will cover 384ft of ground. How many bags of grass

Anit [1.1K]

Answer:

13 bags

Step-by-step explanation:

Area of the lawn: A=lw

w= 64 ft

P= 2(l+w)= 278 ft ⇒

l= 278/2- 64= 75 ft

A= 64*75= 4800 ft²

bags of seed required:

4800/384= 12.5 so 13 full bags needed

Find the slope of the line below. *

earnstyle [38]

Answer:

I believe it would be -3,4.

Step-by-step explanation:

To find slope you use rise over run, where you count up first, then go to the side. If you count down on the left you count 3 boxes, but since its going down its negative. And to get the run you count over 4. Meaning it's -3,4
