What situation could the graph represent?

Mathematics

Answer:

b

Step-by-step explanation:

It can only be b because the graph is steadily decreasing (negative slope). if it's raining, the temperature is above freezing, and then the rain would turn to snow if the temperature dropped below freezing. So that matches the graph.

For a, total rainfall in a day, the total would keep going up, so it would have a positive slope.

For c, the speed of the car would be at 0 at the beginning when in's at the stop sign, and the graph is starting out well above 0.

For d, the graph would have to go up then down to represent the hill.

<h3><u>Answer:</u></h3>
  • Option B
<h3><u>Step-by-step explanation:</u></h3>

This is because it is the most suitable option than other graphs. Let's verify all options.

  • Option A => This does not do anything with the graph.
  • Option B => This is the most reasonable option because it states that the weather changes from rainy to snowy. As the graph decreases, the temperature changes.
  • Option C => This graph is halfway correct, but halfway incorrect. This is because if the speed of the car increases, the graph should increase. However, this graph shows the line decreasing. Hence, this does not do anything of the graph.
  • Option D => This graph is halfway correct, but halfway incorrect. This is because if the speed of the bike increases, the graph should increase. However, this graph shows the line decreasing. Hence, this does not do anything of the graph.

Explain why the system has the answer given. Solve each system by elimination to prove your answer.
andrey2020 [161]

Answer:

<em>Proved below</em>

Step-by-step explanation:

<u>System of Equations</u>

There are several ways to solve a system of linear equations. One of the most-used is the method of elimination which consists in adding two or more equations to eliminate one or more variables.

The system shown in the question has evidently no solutions because we have the same variables related in the exact same way in the left side of both equations and a different number as a result of those operations.

To prove the statement, let's multiply the first equation by -1

-x-2y=-8\\x+2y=20

Adding both equations:

0=12

This false result comes from the fact that we tried to solve a system with no solutions. The only way we could have solved it is that both right sides had been equal

A scientist placed 22.854 grams of sodium chloride in a beaker. He then added five times as much calcium chloride as sodium chlo
expeople1 [14]
The answer is B. 34.281
22.854 + 5(22.954) = 137.124
137.124 divided by 4 = 34.281 = 34.2810

Six teammates are competing for first, second, and third place in a race.
Olegator [25]

Answer:

Therefore, There are 120 possibilities for the top three positions

Step-by-step explanation:

Given that : Six teammates are competing for first, second, and third place in a race.

Total number of teammates in the team = 6

Total number of positions offered for winning in the competition = 3 ( first, second, and third place)

Now, we need to find the number of possibilities for the top three positions

Possibility for 1st position = 6

Possibility for 2nd position = 5

Possibility for 3rd position = 4

\text{So,Total number of possibilities = }6\times 5\times 4=120

Therefore, There are 120 possibilities for the top three positions

Aaron is going to a carnival that has games and rides. Each game costs $2.75 and each ride costs $4.75. Aaron spent $20.50 altog
serg [7]

Answer:

Step-by-step explanation:

2.75g + 4.75r = 20.50

g = 2r

2.75(2r) + 4.75r = 20.50

5.50r + 4.75r = 20.50

10.25r = 20.50

r = 20.50 / 10.25

r = 2 <==== Aaron went on 2 rides

g = 2r

g = 2(2)

g = 4 <==== Aaron played 4 games

check...

2.75g + 4.75r = 20.50

2.75(4) + 4.75(2) = 20.50

11 + 9.5 = 20.50

20.50 = 20.50 (correct)
