The third one. I’ve shown my work below. The first two are positive and the last one is 0, which is neither positive nor negative

I know someone else responded but theres an easier way to solve this without multiplying anything.
Neg*neg=pos
1. Has two neg and two negs make a pos
2. Has 4 neg which will also make pos
3. Has 3 neg. The first 2 will cancel out and make a pos but the last one will make the answer neg
4. Would just be 0 because its multiplying 0 but without it it would be neg.
So the answer is the third one

It’s actually D.

You have to look at both x and y and it’s power. You have to look for the lowest power for x and y. For y as you can see that the lowest power is 2. As for x it can be either power of 3 or even 2. When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.

When you get the answer, please check the answer if it’s the same as the original. Meaning distribution both x^2 and y^2 to inside parenthesis. And for the power, you add them. This way you can double check and see if it’s the same.

The table represents a linear relationship. x: −2, 0, 2, 4 y: −1, 0, 1, 2 Which of the following graphs shows this relationship?

Answers

Answer:

The second graph

Step by Step

First, note down the points given.

(-2, -1) etc

Then find the points on the graphs and see if the line of the graph goes through the point.

(-2,-1): both lines go through this point

(0,0) both lines go through this point

(2,1) only the second graph goes through this point

Therefore, the second graph is the correct answer. You can check the last point if you want to double check.

The first graph is correct because it we see points are seen as (x, y). The points we see in the table are (-2,1) (0,0) (2.1) (4,2). These four points are all seen in the first graph.

When astronauts Neil Armstrong and Buzz Aldrin first walked on
the moon in 1969, they were able to bounce from step to step!
This is because the gravitational force of the moon is about
16.5% of that of the Earth. If you visited the moon,
weighing 100 pounds on Earth, what would your weight be?

Answers

Answer:

16.5 pounds

Step-by-step explanation:

16.5% as a decimal is 0.165

0.165 x 100 = 16.5

So in conclusion you will weigh about 16.5 pounds on the moon.

About 16 if we are counting the fact that the moons gravity is about 16.5 of the earth you will weight 16.5 pounds and will be able to float!

what is 12 divided by 3/4?
correct answer gets brainliest!

Answers

Step-by-step explanation:

To divide by a fraction, we can invert the fraction and multiply.

So, 12 divided by 3/4 can be written as:

12 * 4/3

Simplifying this expression, we get:

= 48/3

= 16

Therefore, 12 divided by 3/4 is equal to 16.

12 divided by 1/3 is 1

9 divided by 1/4 is 2.25

1/8 divided by 4 is 0.5

12 divided by 1/3 is 4

Answers

58% of swimmers swam the race in under 50 minutes

Step-by-step explanation:

29/50 x 2 = 58/100 convert to decimal, 0.58, convert to percent, take decimal symbol and put it to digits to the right, 58%

the reason I doubled the fraction was to make it 100 so you can convert into a decimal a lot easier.

how I got 29/50, 29 out of 50 is the same thing is 29/50.

Tom and Katherine live in different towns which are linked by a bike trail. They agree to meet for a bike ride, and both set off from home at the same time. Tom rides north at a speed of 14 mph and Katherine rides south at 10 mph. The bike trail between their homes is 42 miles long. How long will it be before they meet?

Answers

Answer:

We can start by using the formula:

time = distance / speed

Let t be the time (in hours) for Tom and Katherine to meet.

Tom's distance = Tom's speed x time = 14t

Katherine's distance = Katherine's speed x time = 10t

Since they are riding towards each other, the total distance they cover is the sum of their distances:

Tom's distance + Katherine's distance = 42 miles

14t + 10t = 42

Simplifying:

24t = 42

t = 42 / 24

t = 1.75 hours

Therefore, Tom and Katherine will meet after 1.75 hours of riding.

They will meet in 1.75 hours
