\\ \rm\longmapsto \dfrac{x-3}{4}=\dfrac{x}{2}

\\ \rm\longmapsto 2(x-3)=4x

\\ \rm\longmapsto x-3=\dfrac{4x}{2}

\\ \rm\longmapsto x-3=2x

\\ \rm\longmapsto x-2x=3

\\ \rm\longmapsto -x=3

\\ \sf\longmapsto x=-3

The number of possible seats is an illustration of permutation

There are 1728 possible sitting arrangements

<h3>How to determine the number of seats</h3>

From the question, we have the following highlights:

  • Chris can only take 1 seat (i.e. the central seat)
  • Jo can take 2 seats (i.e. the seats adjacent the central seat)
  • Alex, Barb and Dave can take 3! number of seats
  • Eddie, Fred, and Gareth can take 3! number of seats on the right of Chris.
  • The remaining 4 adults do not have preference, then they can seat in 4! ways

So, the number of sitting arrangement is:

n = 1 * 2 * 3! * 3! * 4!

Evaluate the product

n = 1728

Hence, there are 1728 possible sitting arrangements

Complete equation of the line through (1,4) and (2,2)
lions [1.4K]

Answer:

y = -2x + 6

Step-by-step explanation:

y=mx + c

m is the gradient and c is the y intercept

m = (y 2 - y 1)  / (x 2 - x 1)  = (2-4) / ( 2-1) = -2

y= -2x + c

To find c, just sub one of the coordinates into the eqn:

By using the coordinates (1,4)

4 = -2(1) + c

c = 6

Therefore, the equation is y = -2x + 6

c) A firm is considering an investment that will earn a 6% rate of return. If it were to borrow the money, it would have to pay
statuscvo [17]

no the firm will not do the investment. because if the firm borrows the money & invest it in the project then the return will be 6% but the cost is 8%. so it will lose 2%.  

it also should not invest his own money on the project to get get the 6% return. because he could have loan the money to someone else & get 8% return. therefore his opportunity cost of investing the money is greater than the return.

therefore he should not make the investment .
