Which of the following tables shows a relationship between x and y?

Answer:

Step-by-step explanation:

So first if it was a scale factor 5 you would multiply it by 5 for each side. So for the side of 8 you would multiply it by 5 which is 40 so that side and the other side across from it would also be 40 units. Then for the next one there is 12 units so you do the same 12x5 is equal to 60 so will the one below it.

Then it would be (40 * 2) + (60 * 2)= 80 + 120= 200

So then the perimeter would be 200 units.

Answer:

32/9

Step-by-step explanation:

You have to just divide all of them

22/9 = 2.444444444 (keeps repeating)

24/9 = 2.6666666667

35/9 = 3.8888888889

32/9 = 3.5555555555

Step-by-step explanation:

Answer:

3 is 100 inches

The pole is 100 inches

Seeing as if you take a ruler to that the 50 is half of that whole pole

so another 50 is 100

p(x,y,)=p'(-y,x)

-90°

p(x,y)=p'(y,-x)

180°

p(x,y)=p'(-x,-y)

Answer:

5.2

Step-by-step explanation:

distance(Mercury, Sun) = 5.8 x 10^7

distance(Venus, Sun) = 1.1 x 10^8

distance(Venus, Mars) = 1.1 x 10^8 - 5.8 x 10^7

The subtraction is a little easier if you borrow a power of 10 from the 10^8, multiplying 1.1 by 10.

simply subtract 5.8 from 11.0.

This gives us a result of 5.2 x 10^7.

The number of dollar bills are needed to cover the United States, when 2.5×10^8 dollar bills to cover a square mile area is 9.5×10^¹⁴.

To write the big number in short form, we write them in the positive power of 10.

To write the very small number, we write them in the negative power of 10.

Tyler’s math class found that it would take 2.5×10^8 dollar bills to cover a square mile area.

The surface area of the United States is about 3.8×10^6 square miles.

To find the number of dollar bills are needed to cover the United States, we have to multiply 3.8×10^6 square miles with 2.5×10^8 dollar bills.

Let suppose it needed n dollar bills. Thus,

[tex]n=3.8\times10^6\times2.5\times10^8\\n=3.8\times2.5\times10^6\times10^8[/tex]

When the base is same in multiplication operation, add the power. Thus,

[tex]n=3.8\times2.5\times10^6\times10^8\\n=3.8\times2.5\times10^{6+8}\\n=9.5\times10^{14}[/tex]

Thus, the number of dollar bills are needed to cover the United States, when 2.5×10^8 dollar bills to cover a square mile area is 9.5×10^¹⁴.

Answer:

[tex]\frac{18}{7}[/tex]

Step-by-step explanation:

[tex]2\frac{4}{7}[/tex]

→ Multiply 7 by 2 then add 4

7 × 2 = 14 + 4 = 18 ⇔ Numerator

7 ⇔ Denominator

Answer: 18/7

Explanation: To write a mixed number as an improper fraction, first multiply

the denominator times the whole number, then add the numerator.

So here, we multiply the denominator, 7, times the

whole number, 2, then we add the numerator, 4.

So we have (7 × 2) + 4 or 14 + 4 which is 18.

Finally, we put our new number over our

old denominator and we have our answer, 18/7.

So 2 and 4/7 can be rewritten as the improper fraction 18/7.

Explanation:

The image is not the same size as the preimage. This means a dilation has occurred. Specifically, the image has been shrunk. The scale factor k must be in the interval 0 < k < 1.

-----------

Point B is at (2,2)

It then moves to (1,1)

The scale factor is 1/2 = 0.5

To find the scale factor, you divide the image x coordinate over the preimage x coordinate.

So the triangle is now half as tall and wide compared to from before.

Point A is the center of dilation. The origin is often the default center. The center of dilation is the only point that doesn't move (fixed point).

Answer:

Dilation with scale factor 1/2 = 0.5

Answer: Simon paid $13.55 for the snack.

Plz mark brainliest ;)

Answer:

$13.55

Step-by-step explanation:

ok, so we know that Amber earned $15.50 on saturday and then he spet $6.95 on a movie ticket. so now we need to subtract $6.95 from his orgininal amount which was $15.50.

so $15.50 - $6.95 = $8.55

and then it says that he borrowed money from his friend to purchase a snack and that he now owes $5.00 to his friend so we add the amount of money he had plus the money he now owes his friend.

so $8.55 + $5.00 = $13.55

so in conclution, simon lent amber $5.00 and in total, they paid $13.55 for the snacks.

Hope that helps :)

Let's verify that the left-hand-side and -right-hand-side are different, when we replace x by 6:

(6)^2-4=36-4=32

5(6)=30

As 32 is different from 30, then 6 is not a solution of the equation.

Answer:

10h=m or if you not at that math level yet it would times Hx10=M

Step-by-step explanation:

Answer:

m = 9h

Step-by-step explanation:

you can see that in 5 hours she earns 45 dollars

divide 5 hours by 5 and 45 dollars also by 5

you then find that in 1 hour she earns 9 dollars

so  in h hours she earns 9 times h

which is h = 9h

but in this case it asks for money so it is m = 9h (h is how much hours she worked)
