a=6n-15/3

a=2n-5

HELP HELP HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Arrange the functions in ascending order, starting with the function t
san4es73 [151]
If x is squared, that will be biggest by the end because it gets bigger the quickest. x^2 + 4 is always 4 greater than x^2, no matter what the value of x is.

5x+3 is always 3 greater than 5x also.

Besides that, you can rank them based on their slopes (5x < 7x < 8x, etc.)

So,
5x
5x + 3
7x
8x + 3
x^2
x^2 + 4

You can also just say “eventually” means that they’re asking to find the values of each when x is really big. so just choose x=100, and plug that into each one.

So, to check that order:
5(100) = 500
5(100) + 3 = 503
7(100) = 700
8(100) + 3 = 803
(100)^2 = 10,000
(100)^2 + 4 = 10,004

Those are in ascending order, so that must be the right order!

How do i rewrite this in function form ?
Tema [17]
So now its-x + y = 6 &#10;
but you want it in y=mx+b so 

add x to both sides so that you have y on its own 
so now it's y = 6+x

Can someone explain step by step how to do this and how to get the numbers please? HELP HELP HELP!!

A = 113.1
so the formula for the area of a circle is
A = pi x r^2
-pi is 3.14(rounded)

-r stands for the radius of the circle which is half the diameter so for this circle your r or radius is 6 and the radius is just squared

so when you plug the numbers in the formula it is
A = 3.14 x 6^2(squared)

A = 3.14 x 36

A = 113.1

Polygon C has an area of 40 square units and someone drew a scaled version of polygon C with a scale factor of 1/2 and labeled i
77julia77 [94]

Answer:

20 square units

Step-by-step explanation:

If Polygon C has an area of 40 square units, and we are told that Polygon D is a copy of Polygon C but with a scale factor of 1/2, then everything for Polygon D would just be one-half of what it was for Polygon C. Thus, the area would be half of 40 square units, or, 20 square units.
