Two lines, C and D, are represented by the equations given below:
Line C: y = x + 14
Line D: y = 3x + 2

Which of the following shows the solution to the system of equations and explains why?

(6, 20), because the point does not lie on any axis

(6, 20), because both lines pass through this point

(3, 11), because one of the lines passes through this point

(3, 11), because the point lies between the two axes

Answers

Answer:

(6,20) because both lines pass through this point

Step-by-step explanation:

To solve this you can use the substitution method.

Since both of them are equal to y, substitute one of the equations for y, that way you have x+14 = 3x+2. From here you continue to simplify.

Eliminate x from either side of the equation. For example, subtract x from the side that says "x+14". (Make sure you are also subtracting it from the other side of the equal sign as well.

Once you do this you should now have 14 = 2x+2

In order continue, you now have to get x by itself. So now subtract 2 from both sides of the equation. After doing this, you should have 12 = 2x

You then simplify x by dividing both sides by 2. This will get you x = 6

Now that you have the x-value, substitute that into either of the two equations (it is recommended you substitute it into both equations to make sure you have the correct x-value). For example: If I substitute x into Line C's equation, I will now have y = 6 + 14.

6 + 14 is 20, therefore you're y-value is y = 20

A taxi company charges passengers $2.00 for a ride, no matter how long the ride is, and an additional $0.20 for each mile traveled. The rule c = 0.20m + 2.00 describes the relationship between the number of miles m and the total cost of the ride c.
a. What is the charge for a 1-mile ride?
b. What is the charge for a 2.7-mile ride?


A. $2.20; $2.54


B. $0.20; $0.54


C. $2.00; $2.20


D. $0.20; $5.60

Answers

Answer:

A. $2.20; $2.54

Step-by-step explanation:

Answer:

A. $2.20; $2.54

Step-by-step explanation:

It should give you 2.54.

First, you have to multiply 2.7 miles times .20 miles. It gives you .54, which you are supposed to add 2.00 to it for every ride.

c =0.20m + 2.00

Where c is the cost and m = number of miles,

For a 2.7 mile ride, m = 2.7

c  = 0.20m + 2.00,    m = 2.7

c = 0.20*2.7 + 2

c = 0.54 + 2

c = 2.54

Charge for the ride = $2.54

Answers

Answer:

In the first case x and y be 49 and 47 respectively

In the second case  x and y be 41 and 37 respectively

Step-by-step explanation:

Let us assume the two number be x and y

In the first case

Now

x + y = 96

x - y = 2

2x = 98

x = 49

y = 49 -  2 = 47

So x and y be 49 and 47 respectively

In the second case

x + y = 78

x - y = 4

2x = 82

x = 41

y = 78 - 41 = 37

So x and y be 41 and 37 respectively

Alicia purchased h half gallons of ice cream for 3.50 each p packages of ice cream cones for 2.50 each she purchased 14 items and spent 43$ which system of equations could be used to determine how many of each item Alicia purchased

Answers

Answer:

H + P = 14

3.50H + 2.50P = 43

Step-by-step explanation:

Given that

H denotes half gallons of ice cream

P denotes packages of ice cream cones

Now  

H + P = 14

And,  

3.50H + 2.50P = 43

So, the systems of equations would be

H + P = 14

3.50H + 2.50P = 43

Olly drove 56 km from Liverpool to Manchester.

He then drove 61 km from Manchester to Sheffield.

Olly's average speed from Liverpool to Manchester was 70 km/h.

Olly took 75 minutes to drive from Manchester to Sheffield.

Work out Olly's average speed for his total drive from Liverpool to Sheffield.

Input note: give your answer correct to 1 decimal place.


give right answer brainiest! please help!

Answers

Answer: 57.1 km/ h

Step-by-step explanation:

First find the amount of time it took for Olly to drive from Liverpool to Manchester.

Time = Distance / Speed

= 56 / 70

= 0.8 hours

It took 75 minutes to drive from Manchester to Sheffield. In hours that it:

= 75 / 60 minutes

= 1.25 hours

Total time taken to travel from Liverpool to Sheffield is therefore:

= 0.8 + 1.25

= 2.05 hours

Distance travelled from Liverpool to Sheffield:

= Distance from Liverpool to Manchester + Distance from Manchester to Sheffield

= 56 + 61

= 117 km

Average speed for the whole journey is therefore:

= Distance / Time

= 117 / 2.05

= 57.1 km/ h

Answers

5+8=13
52/13=4
4*5=20
4*8=32
20:32
To get a number in a ratio, add up the two numbers in the ratio:
In this case add up 5 and 8 to get 13 parts.
If 52 is split into 13 parts each part is:
52/13 = 4
We then multiply the number of each part by the total for each side of the ratio so:
5 x 4 = 20
8 x 4 = 32
So the answer is 20:32
We can check by adding the ratio up to see if we get our original number, which we do.
