Answer:

Y=50x + 200

Step-by-step explanation:

For every month, which is represented by X, the overall price, represented by y, goes up by 50 so we must multiply 50 by the number of months on the plan, X. We also have to factor in the one-time cost of the phone plan itself, which is 200 and ALSO does not go up with every month, so we add 200 to the equation of 50x, giving us 50x + 200, all we have to do from here is show what this equation is doing, which is giving us the answer to Y (the overall price of the plan), and we finish with Y=50x + 200

Based on the graph, what is the dependent variable, the equation relating the two variables, and how far will the dragonfly trav

ivann1987 [24]

Answer:

<h2>The dependent variable is distance, the equation is y = 20x, and the dragonfly will travel 480 miles.</h2>

Step-by-step explanation:

According to the graph, the dependent variable is Distance in miles, because it's on the vertical axis. Additionally, the independent variable is time in hours, because it's on the horizontal axis. However, you always put time as independent, because nothing affects time.

To find the equation, we just need to find the slope, using two points (0,0) and (2,40).

$m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }=\frac{40-0}{2-0}=20$

Therefore, the equation is $y=20x$ , which shows a direct proportion between variables.

Now, in 24 hours, it would travel

$y=20(24)=480$

It would travel 480 miles.

Therefore, the right answer is the second choice.

How many dollars do you have if you have 90 nickels, 16 dimes, 16 quarters, and 7 fifty-cent pieces? Show your work and explain

aev [14]

Step-by-step explanation:

90 nickels = 5*90=450=450/100=$4.5,

16 dimes=16*10=160=160/100=$1.6

16 quarters = 25*16=400=400/100=$4

7 fifty-cent pieces = 7*50=350=350/100=$3.5

Total dollars = 4.5+1.6+4+3.5=$13.6

11. Monthly sales revenue, S (in $), and monthly advertising expenditure, A (in $), are modelled by the linear relation, S = 900

Elenna [48]

We are to answer the questions given the sales and advertisement function

The answers are given below

Given:

S = 9000 + 12A

Where,

S = Monthly sales revenue

A = monthly advertising expenditure

a. If the firm does not spend on advertisement

S = 9000 + 12A

Where,

A = 0

S = 9000 + 12A

S = 9000 + 12(0)

S = $9000

b. If the firm spends $800 on advertising one month

S = 9000 + 12A

= 9000 + 12(800)

= 9000 + 9600

= 18,600

S = $18,600

c. S = 9000 + 12A

When

S = $15,000

15,000 = 9000 + 12A

15000 - 9000 = 12A

6000 = 12A

A = 6000/12

= 500

A = $500

d. If the firm increases monthly expenditure on advertising by $1

If A increases to $501

S = 9000 + 12A

= 9000 + 12(501)

= 9000 + 6,012

= 15,012

S increases to $15,012
