It is the 5th Blue one:) We know this because the y-intercept is -2.

Answer:

I can see how this is confusing, because of -2, but the slope is decreasing, so the question wouldn't say:

[tex]-3/5x - -2[/tex]

This happens to turn the -2 into a regular 2 with an addition (+) sign.

and since the graph has an input of 5 but an output of -3, the equation would be:

y = -3/5x + 2

Megan and Desmond each added the same amount of water to their aquariums. Megan mixed 5 mL of a chemical solution with every gallon of water for her aquarium. Desmond mixed 8 mL of the chemical solution with every 2 gallons of water for his aquarium.

Which of these statements is true?

Answers

Answer:

i think it is the second one

Step-by-step explanation:

The statement "Megan added more chemical solution to her aquarium than Desmond did" is true.

What is Unit of Measurement?

A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.

To compare the amount of chemical solution used by Megan and Desmond, we need to convert their rates to a common unit.

Let's convert Megan's rate to mL per 2 gallons by using proportions:

5 mL / 1 gallon = x mL / 2 gallons

Multiplying both sides by 2, we get:

10 mL = x

So Megan added 10 mL of chemical solution per 2 gallons of water.

Desmond's rate is already given as 8 mL per 2 gallons of water, so we can compare their rates directly.

Since 10 mL is greater than 8 mL, Megan added more chemical solution to her aquarium than Desmond did.

Therefore, the statement "Megan added more chemical solution to her aquarium than Desmond did" is true.

Number 2: (look at pivture) 10 point

Answers

Answer:

Step-by-step explanation:

Because the arrow is going 2 in the right direction...so you have to have the 2 in the equation...

and the reason it equals 5 instead of a (-) number is because of the KCC rule

so basically the equation is 2+3

or if you don't want the long way just look at all of the equations...only one of the have a 2 in it so it is automatically the correct answer

Answer:

I think it should be A.

Step-by-step explanation:

The first arrow represents 2, and the second arrow represents subtracting -3 from it, represented as -(-3). This means that the first part of the equation is 2 - (-3). Now you have to solve it. When subtraction is modeled like this with a negative number, it actually means addition. This means that the answer should be as simple as 2+3 because there were two negative signs. 2+3=5, so A should be the answer.

Which of the following is the graph of the inverse of f(x)=2x-3

Answers

Answer:

(-3,0) (0,1.5

Step-by-step explanation:

The answer choice which is the graph of the inverse of f(x)=2x-3 is; the graph of; f(x) = x/2 + 1.5.

What is the graph of the inverse of f(x)=2x-3?

It follows from the task content that the function given is; f(x)=2x-3.

Hence, to find the inverse function;

y = 2x - 3x = y/2 + 1.5.

Interchange the variables;

y = x/2 + 1.5.

On this note, it follows that the inverse function is;

f(x) = x/2 + 1.5

The graph of the inverse function therefore has points; (0, 1.5) and (2, 2.5) as points on the graph.

Robert uses a wheelbarrow to haul wood from his backyard to the back of his neighbor's house, located 9 kilometers away.
1. If he takes 2 breaks evenly when pushing the wheelbarrow the complete distance, at what distance does he take his first break?
2. Robert has 36 pieces to take, but can only take 9 each time. What distance in meters, will he have to travel to move all the wood.

Answers

WHAAAAAAAAAAAAAAAAAAAATTTTTT

Answer:

1. 3 breaks

2. 36,000 meters

Step-by-step explanation:

1. To solve this, we must divide 9 by 3 since the first break, the second break, and the complete distance are all major stops.

9 ÷ 3 = 3

Robert takes 3 breaks.

2. Since Robert has to has to take 36 pieces, but only 9 each time, we must divide 36 by 9.

36 ÷ 9 = 4

He will need to take 4 trips to take all the wood.

However, this question asks the distance in meters. Since 1 kilometer is 1,000 meters, then 9 kilometers is 9,000 meters.

9000 x 4 = 36000 meters
