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 !

Jim have the shopkeeper six coins that totaled 38 cent for a balloon what were the six coins

Katyanochek1 [597]

We are given that

Shopkeeper has six coins

total number of coins =6

we know that

there are four types of coins

(1) cents

1 cent =1 cent

(2) nickels

1 nickel =5 cents

(3) dimes

1 dimes =10 cents

(4) quarters

1 quarter = 25 cents

so, we can use trial and error method

Since, nickels , dimes and quarter are multiple of 5

and there 38 cents

so, three coins must be cent

number of cent coins =3

so, the remaining cent = 38-3=35

so, possible coins can be 1 quarter and 2 nickels

1 quarter + 2 nickels =25+2(5)=35

so, coins were

Number of cents =3

Number of nickels =2

Number of dimes =0

Number of quarter =1..................Answer
