A company produces screens of different sizes. Based on the table, could there be a relationship between the number of pixels and the area of the screen? If so, write an equation representing the relationship.

Answers

Answer
1 in =5184
Step by step

The equation representing the given situation is y = 5184x.

What is an Equation?

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

There are given values for the square inches of screen and the number of pixels.

If there is a proportional relationship between the number of pixels and the area of the screen,

the equation will be of the form y = kx, where k is a constant of proportionality.

31,104 = 6k

k = 31,104 / 6 = 5184

373,248 = 72k

k = 373,248 / 72 = 5184

544,320 = 105k

k = 544,320 / 105 = 5184

1,555,200 = 300k

k = 1,555,200 / 300 = 5184

The equation is, y = 5184x

Hence the equation is y = 5184x.

one side is x+y and another is x-y and when you combine them you would get 2x and the perimeter is 4x+3y so 4x+3y-2x is 2x+3y. I am not 100% sure but I think i'm correct.

Answer:

-1, -1 us answer fir your questions

The last option (-1,-1) is the right answer!
This is because when multiplying both expressions with y which is -1, it gives -3 and -5, and when you add -1 to both -3 and -5, you get -4 and -6 therefore satisfying the solution to the equation! Hope this helps!

ill try to mark you brainly if you show the work cause right now i don't see the button but ill figure it out :)

Answers

Answer:

0.07518

Step-by-step explanation:

First you set up the equation as:

0.537

x0.14

Then, you multiply the problem regularly. Your answer should be 007,518. Now, you add the decimal. My trick to remember this is that in the number 0.537, there are 3 digits after the decimal, so you get the number 3. In the number 0.14, there are 2 digits after the decimal. You get the number 2. You add together the 3 and 2 to get 5. In your number 007,518 place the decimal like this...

The decimal is here right now: 007518.

You move the decimal to the left 5 places: 0.07518

And you have your answer! I hope this helped!
