Can someone please help me do the work

Mathematics
1 answer:
Alla [95]3 years ago

Answer:

C. 1 and 3

Step-by-step explanation:

You are right, now here's why.

You are looking for two equations that have the same constant of proportionality.  That means they behave the same, that if you enter a X value in one, you'll get the same effect as if you enter it in another.

If you look at all four equations, you'll see that 1 and 3 are essentially the same thing, just that the first one is simplified (4y = 3x) while the other isn't (8y = 6x).  But for each time you enter a X value, the Y value will be 33% (1/3) bigger.

Find u in terms of m,g and v in this equation E = m/2g(v²-u²)<br>​
igor_vitrenko [27]

Step-by-step explanation:

E = m/2g(v²-u²)

2g×E = 2g×m/2g(v²-u²)

2Eg = m(v²-u²)

2Eg = mv² - mu²

mu²= mv² -2Eg

mu²/m = mv² -2Eg /m

u²= v² -2Eg

u = √v²-√2Eg

SOVA2 [1]

Answer:

-4x + y + 6z

Step-by-step explanation:

Combine like terms (Terms with the same variable):

(2x + 5y - z) + (-6x - 4y + 7z)

Add straight across:

2x - 6x = -4x

5y - 4y = y

-z + 7z = 7z - z = 6z

-4x + y + 6z is your answer.

HARDEST QUESTION IN THE ENTIRE WORLD. CAN YOU SOLVE?
makvit [3.9K]
Hello, there!


The distance from Mia to Eva is 15 feet, and the distance from Mia to Abigail is 25 feet. A triangle is drawn connecting the positions of Mia, Abigail, and Eva. How far is Eva from Abigail if the angle marking Mia’s position is 50°?



Let's pretend that:


Mia is point A


Abigail is point B


Eva is point C.


The answer is 19.2 feet.


That means that the answer is C


I have drawn the triangle to scale, and attached it below. That way, you can see how I got this answer.



I hope I helped!


Let me know if you need anything else!
