Christian pays $15 to join a music streaming service. He also pays $0.99 for each song he downloads from the same service.
Which function can be used to find, y, the the amount of money Christian spends for x downloaded songs?
y = 0.99x + 15
y = 15x + 0.99
y = 15x
y = 0.99x
The total amount of money Christian spends to download x xongs is y = 15 + 0.99x.
Christian initially pays $15 to join the music service.
Also, he pays $0.99 for each song he downloads from the service.
If he downloads x songs, the amount extra he pays per song he downloads is price per song × number of songs = $0.99 × x = $0.99x.
This amount is added to the initial $15 he pays to join the service. So, the total amount of money he pays is y = initial amount + extra per song = $15 + $0.99x = $0.99x + $15
So, the total amount of money Christian spends to download x xongs is y = 15 + 0.99x.

spilled $40 into the ratio of 3:7
Answer:
$12/$28
Step-by-step explanation:
Let x and y represent the two amounts of money adding up to $40.
Assume that x is the smaller amount. Then:
x 3
----- = ----- Remembering that x + y = $40, we get x = $40 - y
y 7
amd sp we have
$40 - y 3
-------------- = ------ which, after cross-multiplication, is $280 - $7y = 3y
y 7
Simplifying this, we get $280 = 10 y, so that y must be $28. If y = $28, x must be $40 - $28, or $12.
$12
Then $40, split in the ratio 3/7, is the ratio ----------------
$28
Check: Note that $12 + $28 = $40, as required, and that $12/$28 = 3/7.
Which slope is perpendicular to slope m= 5/6
Answer:
-6/5
Step-by-step explanation:
The slope of perpendicular lines multiply to -1
5/6 * p = -1
Multiply each side by 6/5
6/5 * 5/6 * p = -1 * 6/5
p = -6/5
The slope of the perpendicular line is -6/5
If you subtract a negative number from that same number you are taking a negative amount from the negative number you started with which means you are making it more positive. Subtracting a negative number is the same as adding a positive one. Such as (-5) - (-6) = 1.

You and three friends will be going out to eat at your favorite restaurant!
Each of you will order three items of your choice. You will also need to leave a tip. If you split the bill evenly among all four of you, how much will each person need to contribute?
Locate a menu for your favorite restaurant and pick three items for yourself and each friend. Make sure all or some of the items differ for each person.
List the restaurant name, items, and prices in a table like the one below.
In the column labeled Subtotal, determine the cost of each person’s order.
The customary tip is 20% of the total bill. In the column labeled Tip, calculate the amount of tip each person should leave.
In the column labeled Total Bill, determine the total of each person’s order, including the tip.
Restaurant name:
Names Item 1 Price Item 2 Price Item 3 Price Subtotal Tip Total Bill
Your name
Friend #1
Friend #2
Friend #3
Part 2: Questions
Answer the following questions, showing all work:
What is the total cost of the entire bill (all four meals), including tip?
Write an expression using fractions to show how to determine the amount that each person will pay. Then calculate each person's contributions showing all steps in long division.
If each person paid an equal amount, who would save the most money? Explain your reasoning using at least two complete sentences.
Answer: All four friends would have to share paying the tip and the total so all of them would pay 1/4 of the bill and 1/4 of the tip
Step-by-step explanation: divide the bill and tip between the 4 friends and you get 1/4 which is how much of the bill and tip that all you and the friends have to pay

Option 3 : 19m, 34m, 15mStep-by-step explanation:
First we must know this,
The length of the third side of a triangle must be less than than the sum of the lengths of any two sides of a triangle.
So, Now let us check one by one :
Option 1 : 5m, 6m, 8m
5 + 6 > 86 + 8 > 55 + 8 > 6So, 5m, 6m, 8m can form a triangle .
Option 2 : 10m, 10, 2m
2 + 10 > 1010 + 10 > 210 + 2 > 10So, 10m, 10m, 2m can form a triangle .
Option 3 : 19m, 34m, 15m
19 + 15 ≯ 34So, 19m, 34m, 15m cannot form a triangle .
Option 4 : 3m, 16m, 14m
3 + 14 > 1616 + 14 > 316 + 3 > 14So, 3m, 16m, 14m can form a triangle .
Carlos bought a new cell phone. The graph represents the
relationship between the number of minutes he uses
and the total
cost. What is the equation of the line?
A) y= 5x + 0.1
B) y=0.1x + 5
C) y=0.5x + 5
D) y = 5x + 5
Answer:
B : y = 0.1x + 5
Step-by-step explanation:
using the y = mx + b equation
b is the intercept on the y axis ( x = 0)
m is the slope of the line.
From the graph we can see that the intercept is (0,5), therefore b = 5;
To calculate slope (m) pick two pints on the line e.g (100, 15) and (0, 5)
m = (y2 - y1)/(x2 -x1) = (15 - 5)/(100 - 0) = 10/100 = 0.1
m = 0.1
therefore in y = mx + b
y = 0.1x + 5

How do I find x in this problem, x/5-2/3=3/2
Answer:
x = 38/6
Step-by-step explanation:
x/5 - 2/3 = 3/2
3x - 2x5/3x2 = 3/2
3x-10/6 = 3/2
2(3x-10) = 3x6
6x-20 = 18
6x = 18+20
6x =38
x =38/6 or x = 6.33

A man standing near a radio station antenna observes that the angle of elevation to the top of the antenna is 64 He then walks 68 feet further away and observes that the angle of elevation to the top of the antenna is 43 Find the height of the antenna to the nearest foot.
The height of the radio station antenna is approximately 116 feet to the nearest foot.
From the diagram in the attached image
[tex]h=\text{the height of the radio station antenna}\\x=\text{the distance from the foot of the radio station antenna to where the man stood at first}[/tex]
we now have the following relationships
[tex]tan64^\circ=\frac{h}{x}\\\\\implies x=\frac{h}{tan64^\circ}[/tex]
and
[tex]tan43^\circ=\frac{h}{68+x}\\\\\implies x=\frac{h}{tan43^\circ}-68[/tex]
we can equate the two relationships to eliminate [tex]x[/tex].
[tex]\frac{h}{tan64^\circ}=\frac{h}{tan43^\circ}-68[/tex]
solving for the height of the radio station antenna, [tex]h[/tex], we get
[tex]h=\frac{68\times tan43^\circ \times tan64^\circ}{tan64^\circ -tan43^\circ}\approx 116ft\text{ (to the nearest foot)}[/tex]

The sum of two numbers is 64 Twice the larger number plus five times the smaller number is 20. Find the two numbers
Answer:
The numbers are 100 and -36.
Step-by-step explanation:
Let x be the larger number
64 - x be the smaller number
x + ( 64 - x ) = 64
2x + 5 ( 64-x ) = 20
2x + 320 - 5x = 20
-3x = -300
x = 100
64 - 100 = -36
