Assignment #17 Slope from points

Find the slope from the points

This is for algebra 1 and I need help!!

Answer: 13

Step-by-step explanation:

3X + 3 - 3 = 42 - 3

3X = 39

3X/3 = 39/3

X = 13

Which means that the first number is 13, the second number is 13 + 1 and the third number is 13 + 2. Therefore, three consecutive integers that add up to 42 are 13, 14, and 15.

13 + 14 + 15 = 42

We know our answer is correct because 13 + 14 + 15 equals 42 as displayed above.

The correct answer is the letter D

Answer:

d

cuz im a goddddd

Answer:

I suppose that each number is repeated 3 times, the actual question is:

Courtney walked from her house to the beach at a constant speed of 4 kilometers per hour, and then walked from the beach to the park at a constant speed of 5 kilometers per hour. The entire walk took 2 hours and the total distance Courtney walked was 8 kilometers.

Now, remember the relation:

Distance = Speed*Time

Let's define:

D1 = distance between Courtney's house and the beach.

D2 = distance between the beach and the park.

T1 = time that it took the first walk.

T2 = time that it took the second walk.

We know that the total distance Courtney walked is 8km, then:

D1 + D2 = 8km.

And we also know that the entire walk took 2 hours, then:

T1 + T2 = 2h.

We also have the equations:

D1 = 4km/h*T1

D2 = 5km/h*T2.

Then we have a system of equations:

D1 + D2 = 8km

T1 + T2 = 2h

D1 = 4km/h*T1

D2 = 5km/h*T2.

To solve this, first let's replace equations 3 and 4 in the first equation:

4km/h*T1 + 5km/h*T2 = 8km

Now we have only two equations left:

4km/h*T1 + 5km/h*T2 = 8km

T1 + T2 = 2h

Now we can isolate one of the variables in the second equation and then replace it in the first equation, i will isolate T1:

T1 = 2h - T2.

Replacing this in the first equation gives:

4km/h*(2h - T2) + 5km/h*T2 = 8km

Now let's solve this for T2.

8km - 4km/h*T2 + 5km/h*T2 =  8km

8km + 1km/h*T2 = 8km

1km/h*T2 = 0

from this, we have T2 = 0

This would mean that T1 = 2h.

Then:

D1 = 4km/h*2h = 8km.

T2 = 0

D2 = 5km/h*0 = 0.

This happens because the numbers in the problem were not well thought.

You can see that when she spends the 2 hours walking at the smaller speed, she already reaches the total distance, then if she walked any amount of time at the larger speed, the total distance would be more than 8km.

Answer:

32 Nickels

Step-by-step explanation:

Given

Coins: Nickels (N) and Dimes (D)

$0.05 = 1 nickel and $0.10 = 1 dime

So, the amount implies:

[tex]0.05N + 0.10D = 6.20[/tex]

The number of coin implies:

[tex]D = 14 + N[/tex]

Required

Determine the number of nickels found

Substitute 14 + N for D in [tex]0.05N + 0.10D = 6.20[/tex]

[tex]0.05N + 0.10(14 + N) = 6.20[/tex]

[tex]0.05N + 1.4 + 0.10N = 6.20[/tex]

Collect Like Terms

[tex]0.05N + 0.10N = 6.20 - 1.4[/tex]

[tex]0.15N = 4.8[/tex]

Solve for N

[tex]N = 4.8/0.15[/tex]

[tex]N = 32[/tex]

Hence, he found 32 nickels

Answer:

Step-by-step explanation:

remember, rise over run

My I have brainliest please? :)

Answer:

The points would be:

1.5

4.5

-2

-4

1

-2.5

4

3

-3.5

5

Step-by-step explanation:

We know, distance between two points A( p,q) and B(r,s) is given by :

[tex]AB=\sqrt{(p-r)^2+(q-s)^2}[/tex]

So, distance between P an Q is :

[tex]PQ=\sqrt{(-7-4)^2+(6-6)^2}\\\\PQ=11\ units[/tex]

Distance between Q and R is :

[tex]QR=\sqrt{(4-4)^2+(6-(-6))^2}\\\\QR=12\ units[/tex]

Distance between R and S is :

[tex]RS=\sqrt{(4-6)^2+(-6-(-6))^2}\\\\RS=\sqrt{4}\\\\RS = 2\ units[/tex]

Therefore, total distance is 11 + 12 + 2 = 25 units.

Hence, this is the required solution.

Answer:

-3(2+7) = -27

Step-by-step explanation:

Answer:

37

Step-by-step explanation:

2-digit number: 10x + y

y = x + 4

20x + 2y = 10y + x + 1

8y = 19x - 1

8x + 32 = 19x - 1

11x = 33

x = 3

♡ The Question ♡

-MY REAPORT CARD IS COMING SOON AND I HAVE ALL F'S my mom snitches and would tell everyone like she did last time so before my mom get's it should I

A. run away from home

B. Break her phone

C. blackmail her, when she DOES get it

*୨୧ ┈┈┈┈┈┈┈┈┈┈┈┈ ୨୧*

♡ The Answer ♡

- None of the Above!

*୨୧ ┈┈┈┈┈┈┈┈┈┈┈┈ ୨୧*

♡ The Explanation/Step-By-Step ♡

- A would not be a very good idea, running away from home can get you in trouble either from your parents/family/guardians, or police/fire department, that would most likely upset your mother more and could cause some issues. B wouldn't be good because soon enough she will most likely find out, breaking somebody's phone can be a bad idea too, if they're in danger they won't be able to call anybody or ask for any help. Including something important could be saved there, not to mention phones are very expensive and it could be devastating.

C isn't much of a better idea either, blackmailing somebody isn't something to be proud of and if anything, is very risky. Blackmailing is demanding money from somebody in return for not revealing compromising info about the person you're threatening. This may only be reputation ruining, but not to mention if the police/fire department find out you're threatening somebody for money you could most likely get arrested.

Answer:

It's also 52  If I got it wrong I'm so sorry but I'm good at angles

Step-by-step explanation:

Answer:

264  {feet}

below sea level

Step-by-step explanation:

Ascending means moving towards the surface.

So the submarine is 340 feet below sea level.

The submarine ascends 76 feet.

∴

340 − 76  =

264  below sea level.

Answer:

The indifference point is 20 minutes

Step-by-step explanation:

Giving the following information:

Tantasic:

Reservation fee of 20$ and $1 per minute

Bettersun:

2$ per minute.

First, we need to structure both total cost formulas:

Tantasic= 20 + 1x

Bettersun= 2x

x= number of minutes

Now, we equal both formulas and isolate x:

20 + 1x = 2x

20 = 1x

20= x

The indifference point is 20 minutes

Answer:

0.46 is the left over 23/50 is the fraction

Answer:

y = -2/5x - 6

Step-by-step explanation:

Slope intercept follows the y = mx + b, which m is the slope, and b is the y intercept.

1. Find the slope:

The formula for slope is the change in y/ over the change in x. Or you can say rise/run.

In other words you can take any of those 2 dots, first count them to the other dot, which is -2, then count horizontally, which is 5, so the slope is -2/5

Another way:

Another way is to take any two points, like (-10, -2), and (-5, -4).

Then we can do -4 -(-2)/-5 -(-10), which is -2/5.

So the equation we have so far is y = -2/5x + b

2.Find the y intercept

Based on the graph, the y intercept is -6, so we get

y = -2/5x - 6

Answer:

  The domain is always discrete when it is found from a table.

Step-by-step explanation:

A table necessarily lists a finite number of discrete points. The domain, as found from a table, is always discrete.

__

If the table is said to be a representation of a continuous function, then the domain of that continuous function will be continuous.

Your question seems to have to do with a table alone, not a table and an equation, or a table and a graph. A table (of points) alone cannot express a continuous domain.

__

Additional comments

One can conceive of tables that would have continuous domains, as, for example, a table with entries ...

  (x, y) = (0 ≤ x < 3, 3x+2), (3 ≤ x < 6, 4x-1), ...

Such a table is not a list of points, but is a piecewise function definition. We presume this is not what you're concerned with.

?=65°

Answer/Step-by-step explanation:

An equation that describes the relationship can be written as [tex] y = mx [/tex].

Using the two sets of coordinates, (2, 140) and (4, 280), calculate the slope (m) as shown below:

[tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{280 - 140}{4 - 2} = \frac{140}{2} = 70 [/tex]

Substitute m = 70 into [tex] y = mx [/tex]

The equation would be:

[tex] y = 70x [/tex]

This equation can be interpreted as follows:

The heart's resting rate is 70 beats each minute.
