suppose you create a graph of the cost function, c=20n + 500 of a new bookstore, and you also graph the revenue function, r=25n,
sdas [7]

Answer:

Loss section

Step-by-step explanation:

Given

c = 20n + 500 -- cost

r = 25n -- revenue

Required

Determine where n = 150 is

To do this, we substitute 150 for n in the given functions

c = 20n + 500

c = 20 * 150 + 500

c = 3500

r = 25n

r = 25 * 150

r = 3750

The above shows that the revenue is greater than cost for n = 150.

This implies that, n = 15o is the loss section.

Answer:

  • (3y)(2x^2 -1x -8xy +4y)
  • (3y)(x -4y)(2x -1)

Step-by-step explanation:

<u>Part A</u>: All of the coefficients have a common factor of 3. All of the variable products have a common factor of y, so the greatest common factor of all terms is 3y. The expression can be written as ...

  (3y)(2x^2 -1x -8xy +4y)

__

<u>Part B</u>: The remaining factor can be factored pairwise:

  3y(x(2x -1) -4y(2x -1)) = 3y(x -4y)(2x -1)

Two parallel lines are cut by a transversal and form a pair
Novosadov [1.4K]

Answer:

since alternate exterior angles are congruent, you get:  

6x + 5 = 7x - 4  

subtract 6x from both sides of this equation and add 4 to both sides of this equation to get 5 + 4 = 7x - 6x which results in 9 = x

 

solve for x to get x = 9 degrees.

If C=(a,b,x,y) and D=(m,n,o,p) then c union d is
Ilya [14]

Step-by-step explanation:

here,

C={ a,b,x,y}

D ={ m,n,o,p}

now,

C union D ={a,b,x,y} union {m,n,o,p}

= {a,b,x,y,m,n,o,p}

therefore C union D ={ a,b,x,y,m,n,o,p}
