Q#1: Amanda and Lisa are playing games at the arcade. Amanda started with $15, and the machine she is playing costs $0.75 per game. Lisa started with $13, and her machine costs $0.50 per game. After how many games will the two girls have the same amount of money remaining?
Q#2:The Lone Star Shipping Company charges $14 plus $2 a pound to ship an overnight package. Discount Shipping Company charges $20 plus $1.50 a pound to ship an overnight package. For what weight is the charge the same for the two companies?

Answers

Let D = the amount of money Deanna has after x games.

We know Deanna started with $15 and she spends 0.75 per game, so we can make the following equation:
D = 15 - 0.75x

Let L = the amount of money Lisa has after x games.

We know Lisa started with $13 and she spends 0.50 per game, so we can make the following equation:
L = 13 - 0.5x

The question is asking how many games need to be played for L and D to be equal, so just equate L and D and solve for x:

D = L
15 - 0.75x = 13 - 0.5x
15 - 13 = -0.5x + 0.75x
2 = 0.25x
2 = (1/4)x
8 = x

Therefore they need to play 8 games each to have the same amount of money.

Answer: For question one its 8

Step-by-step explanation: Let A be the variable for Amanda! The amount of money she has for x amount of time. We know that lisa has $13 and she is spending .50 every game. The equation for this would be L=13-0.5x. SO to solve this problem of when they both will have the same amount of money use the equation. 15- 0.75x=13 - 0.5x then you will switch the equation around. So the next step would look like 15-13= -0.5x + 0.75x! Then you'll get 2=0.25x change that to a fraction and you'll get 1/4 and 8=x!

Answer:

The y-intercept in coordinate form is (0, 2.9), which the y-intercept represents the pickup fee which is $2.90 before any mileage

Step-by-step explanation:

Hello, I do apologize that no one responded for two hours.

1 - Understanding what it means to be a y-intercept

When mathematics presents the "y-intercept" its the unimaginative way of saying "Where the equation crosses the y-axis"

Looking at a graph we can deduce that, the y axis in traditional graphs is always at the x value of 0.

What can this mean for this situation?

We want to find out how much each person with 0 miles or no miles driven.

This will be our pickup fee alone

How can we do this?

Theres multiple ways, however the way I like is to set an equation to zero.

2 - Slope Intercept Form

We need to get it into the slope-intercept form using data given to us to use as our equation.

For reference the slope-intercept form is

y = mx + b

y = y value

m = slope

x = x value

b = y - intercept

2.1 - Find the slope

for y = mx + b we'll need to find our slope, m, and to do so we use the following formula

[tex]slope = m = \frac{\triangle y}{\triangle x} = \frac{change~in~y}{chnage~in~x} = \frac{y_2 ~ - ~ y_1}{x_2 ~ - ~ x_1}[/tex]

To do this we need to assign x values and y values.

Our total cost is our y value, because its a total, and our variable is x which will be our miles.

(x value is always the variable, and our y value is always the totals)

So now looking at the data;

Gus;

$12.00 for a 6.5-mile journey

Tony;

$15.50 for a 9-mile journey

We can deduce at 6.5 miles we'll pay $12, and at 9 miles we'll pay $15.50

Because 6.5 is less than 9 our x1 and y1 will be deduced from that, and with that in mind, let's solve that equation.

POINT → (x, y)

(6.5, 12)

(9, 15.50)

[tex]\frac{y_2 ~ - ~ y_1}{x_2 ~ - ~ x_1} = \frac{15.50 ~ - ~ 12.00}{9 ~ - ~ 6.5} = \frac{3.5}{2.5} = 1.4[/tex]

Our slope is 7/5, so therefore,

y = mx + b

      =

y = 1.4x + b

2.2 - Plug and chug to find our y-intercept, b.

We'll need to plug in a point into the unfinished equation to solve for b

y = 7/5x + b

In this instance let's use (6.5, 12)

(x, y)

12 = 1.4(6.5) + b

12 = 9.1 + b

-9.1  -9.1

2.9 = b

Lets plug that in to our y = mx + b

y = 1.4x + b

        ↓

y = 1.4x + 2.9

And would you look at that, just by setting up the equation we now know our y-intercept, now if you recall from earlier one of my notes said this:

POINT → (x, y)

This is the same thing as coordinate form I'm assuming, and as a result, we have all the information we need to answer the problem.

3 - Putting it together to answer the problem

 POINT → (x, y)

           =

Coordinate Form:

           =

        (x, y)

Now remembering what I said earlier, the y-axis, is always on x = 0

So our y-intercept in coordinate form is;

(0, 2.9)

This means;

The pickup fee is $2.90 which excludes any mileage.

See the answer for it put together

Hope this helps :)

PLEASE HELP ME!!!!!!The Metamorphosis worksheet on commonlit In all the history of scientific discovery there has never been, perhaps, so general, rapid, and dramatic an effect wrought on the scientific centres of Europe as has followed, in the past four weeks, upon an announcement made to the Wrzburg Physico-Medical Society, at their December meeting, by Professor William Konrad Rntgen, professor of physics at the Royal University of Wrzburg. The first news which reached London was by telegraph from Vienna to the effect that a Professor Rntgen, until then the possessor of only a local fame in the town mentioned, had discovered a new kind of light, which penetrated and photographed through everything. This news was received with a mild interest, some amusement, and much incredulity; and a week passed. Then, by mail and telegraph, came daily clear indications of the stir which the discovery was making in all the great line of universities between Vienna and Berlin. Then Rntgen's own report arrived, so cool, so business-like, and so truly scientific in character, that it left no doubt either of the truth or of the great importance of the preceding reports. . . .Exactly what kind of a force Professor Rntgen has discovered he does not know. As will be seen below, he declines to call it a new kind of light, or a new form of electricity.
