A football team plays in a large stadium. With a ticket price of $17, the average attendance at recent games has been 50,000.

Verizon [17]

Answer:

a. N(x) = 50000 - 200x

b. R(x) = (50000-200x)(17+x)

Step-by-step explanation:

a. Given,

The the original price of each ticket = $ 17,

Also, the average attendance = 50,000

Let x be the number of times the original price of each ticket is increased by $ 1,

Also, for each $1 increase in the ticket price, attendance decreases by 200,

Thus, decrements in the attendance = 200x,

If N(x) represents the new average attendance,

Then,

N(x) = 50000 - 200x

Which is the required function,

b. Now,

Revenue = average attendance × price of each ticket

R(x) = N(x) × ( 17 + x )

⇒ R(x) = (50000-200x)(17+x)

Which is the required function.

If 2x – 10y = -1 and 5x + 6y = 4 are true equations, what would be the value<br> of 7x - 4y?

Zigmanuir [339]

Answer:

Step-by-step explanation:

If the equations are true, they can be solved simultaneously.

Consider 2x-10y=-1 as Eq1 and 5x+6y=4 as Eq2

Multiplying Eq1 with 3 and Eq2 with 5 we get,

6x-30y=-3 -- Eq3 and 25x+30y=20 -- Eq4

Adding Eq3 and Eq4,

31x=17 Therefore, x=17/31

Plugin x=17/31 in Eq3,

6(17/31)-30y=-3 --- y=13/62

Plug In values of x and y in 7x-4y we get,

7(17/31)-4(13/62) = 3

So the value of 7x-4y = 3.

Fernanda and Jose were working on an assignment in their geometry class in which they were to write the equation of the graph be

Alborosie

Answer:

yes they both are wrong

Step-by-step explanation:

Center of the Circle is (h,I) which is (4,-3)

so h= 4 and k = -3

radius is 4 units (3+1)

Equation for circle

$(x - h) {}^{2} + (y - k) {}^{2} = r {}^{2}$

substitute all the values in this equation

$(x - 4) { }^{2} + (y - ( - 3)) {}^{2} = 4 {}^{2} \\ (x - 4) {}^{2} + (y + 3) {}^{2} = 16$
