(-3, -2) is the vertex.
You can find this by plugging into -b/2a to find the x value and using the x value to find the y value.
And another spot on the vertex would be (0, 16), which is the y intercept.
We know that this ratio is directly because the two magnitudes go up.
In this case we will get the <u>proportionality constant</u> by dividing any term of the second magnitude by the first.
<h3>For example: </h3>
Now that we know that k = 3, we can know how much "<u>y</u>" will be if <em>x = 5</em>.
We just multiply:
<h3>Answer: <u>y = 15</u></h3>
Step-by-step explanation:
The root is
-sqr root of 5.
First, we put these roots in the forn of
where a is the root
So we have
To get rid of that square root, let have another root that js the conjugate posive root of 5.
Which will gives us a rational coeffeicent of degree 4.
Why we didn't do
?
Because
If we foiled out we will still have a irrational coeffceint.
Answer:
6425 pounds
Step-by-step explanation:
If 1 TV weighs = 12.85 pounds
then 500 TVs weigh = 12.85 x 500
= 6425 pounds
