Why is graphing not always the best option for solving systems?
RideAnS [48]
1, Might not be precise 
2, Can be hard to plot the graphs
3, If there are many solutions that will be really hard to plot sometimes. 

This is just from the top of my head.

I need some help on this question please
elena-s [515]

Answer:

15

Step-by-step explanation:

Ok so first you need to know how to calculate the volume of a cylinder

I will put the formula here:  V=πr2h

Since pi is equal to 3.14 as said in the problem we can simply divide 282.6 by pi, the radius and 2

That is equal to 282.6/3.14*3*2

A little calculation shows that, the answer is 15

Hope this helps :)

What would a piece 430 feet 3 inches cost if you get a 10% discount for the larger volume? A piece of wire cable 180 ½ feet long
alexgriva [62]
To get the answer to this question you would have to multiply these numbers.
The normal price appears to be 65.95 for 180.5 feet. 
First we could divide 430.25 by 180.5
This divides out to become 2.39027778.
We would then multiply This by our normal price for 180.5 feet, which is 65.95.
This gives us 157.63882.
We would next need to take the 10 percent off. The easiest way to do this is to multiply our price by .90
This would give us 141.484938.

What is 4,7,12,19,28 in quadratic form
Naddik [55]
Asked and answered elsewhere.
brainly.com/question/9247314

You obviously don't mind using "technology" (Brainly) to answer these questions. A graphing calculator can do quadratic regression on the sequence and tell you its formula.

If you want to do it by hand, you can write the equation
.. y = ax^2 +bx +c
and substitute three of the given points. Then solve the resulting three linear equations for a, b, and c.
.. 4 = a +b +c
.. 7 = 4a +2b +c
.. 12 = 9a +3b +c

Subtracting the first equation from the other two reduces this to
.. 3 = 3a +b
.. 8 = 8a +2b
The latter can be divided by 2, so reduces to
.. 4 = 4a +b
Subtracting the first of the reduced equations from this, you have
.. 1 = a
so
.. 3 = 3*1 +b
.. 0 = b
and
.. 4 = a + b + c = 1 + 0 + c
.. 3 = c

And your equation is
.. y = x^2 +3 . . . . . . as shown previously

How do you solve this? x - 2y = 4
valentina_108 [34]
If you want to solve for x, then
add 2y to both sides
x=2y+4
if want to solve for y
minus x both sides and divide by -2
x-2y=4
-2y=-x+4
y=1/2x-2
