Answer:

\sf\longrightarrow \boxed{\pink{\sf 3x + 4y -8=0}}

Step-by-step explanation:

We need to write the slope intercept form of the equation which passes through (4,-1) and parallel to the line y = -3/4x .

We know that the line parallel to a given line has the same slope . Therefore the slope of the line will be , ( on comparing to Slope Intercept Form ) .

\sf\longrightarrow Slope =\dfrac{-3}{4}

On using point slope form ,

\sf\longrightarrow  y-y_1= m ( x - x_1)

Substitute the respective values ,

\sf\longrightarrow y - (-1) = \dfrac{-3}{4}( x - 4 )

Simplify ,

\sf\longrightarrow y +1 = \dfrac{-3}{4}x + 3

Multiply both sides by 4 ,

\sf\longrightarrow 4y + 4 = -3x + 12

Put all terms on same side , i.e. on LHS ,

\sf\longrightarrow \boxed{\pink{\sf 3x + 4y -8=0}}

<u>Hence</u><u> the</u><u> </u><u>equation</u><u> of</u><u> </u><u>the</u><u> line</u><u> </u><u>is </u><u>3x</u><u> </u><u>+</u><u> </u><u>4</u><u>y</u><u> </u><u>-</u><u> </u><u>8</u><u> </u><u>=</u><u> </u><u>0</u><u>. </u>

A math club is researching a golf tournament fund-raiser. it will cost $1,000 to host the tournament. if it rains, the club will
Readme [11.4K]

The expected value of tournament is $2600.

According to the statement

we have given that the tournament will cost $1000 and if it is sunny, it is expected that the club will collect $4,500 from the participants. And we have to find the expected value of a tournament.

So, we know that the

Cost of hosting the tournament : $1,000

If it rains, the club will lose the investment: $ -1,000

If it is sunny, the club will collect $4,500 ;

From all this the profit they will get

profit: 4,500 - 1000 = 3,500

And

There is a chance of 20% then

The club will loss the investment is

-1000*20 = -200

And

Effect on their profit if there is a rain then

3500*80 = 2800

then

The expected value of tournament is 2800-200=2600.

So,The expected value of tournament is $2600.
