Valentin [98]

Answer:

Part A: 7n + 30= -5 and 8n + 40= 16

Part B: 7(8) + 30= 86 and 8(8) + 40= 104

Part C: Company A saves you 12.

Step-by-step explanation:

Company A: 7n + 30

Company B: 8n + 40

7n + 30= -5       8n + 40= 16

7(8) +30= 86     8(8) +40= 104

7(2) + 30= 44    8(2) + 40= 56

56 - 44= 12

solmaris [256]

Answer:

The function will be: f(n) = 2n

Step-by-step explanation:

An arithmetic sequence is a sequence where the common difference between consecutive terms is same

The sequence according to given information is:

2,4,6...

Here

a_1 = 2

a_2 = 4

a_3 = 6

the common difference will be:

d = a_2-a_1 = 4-2 = 2\\d = a_3-a_2 = 6-4 = 2

The arithmetic sequence is given by:

a_n = a_1+(n-1)d

Putting the values

a_n = 2+(n-1)(2)\\a_n = 2+2n-2\\a_n = 2n

Hence,

The function will be: f(n) = 2n

It has been estimated that the price elasticity of demand for attending baseball games is 0.23. Other things held constant, a 10
Akimi4 [234]

Answer:

Correct option: (A) 43.48% fall in the price of a ticket.

Step-by-step explanation:

The price elasticity of demand is defined as the percent change in quantity demanded to the percent change in the price.

Price\ elasticity\ of\ demand=\frac{\%\ change\ in\ quantity\ demanded}{\%\ change\ in\ price}

Given:

Price elasticity of demand = 0.23

% change in quantity demanded = 10

Compute the % change in price as follows:

Price\ elasticity\ of\ demand=\frac{\%\ change\ in\ quantity\ demanded}{\%\ change\ in\ price}\\0.23=\frac{10}{\%\ change\ in\ price}\\{\%\ change\ in\ price}=\frac{10}{0.23}\\=43.4783\\\approx43.48

Thus, a 10 percent increase in attendance can be explained by a 43.48% fall in the price of a ticket.

Solve the following inequality. -5-2x&gt;-9. Show all work you did to get the answer
Elena L [17]

Answer:

x

Step-by-step explanation:

Solving inequalities is just like solving equations. Isolate x and whatever you do to one side, you must do to the other.

1) First, isolate the term with the x. To get rid of the -5, add 5 to both sides.

-5-2x>-9\\-2x>-4

2) Next, isolate the variable x by dividing both sides by -2. However, remember that when working with inequalities, you must flip the inequality sign when dividing or multiplying by a negative number. Thus, the greater than sign becomes a less than sign.

-2x>-4\\x

Thus, the answer is x.
