y^2 = x isn't a function because there is at least one value of x that produces multiple values of y. In fact, any x value greater than 0 yields two y values. If x = 0, then y = 0 is the only solution. ... Graphically, the equation fails the vertical line test, which is another way to determine that it is not a function.
Answer: 
Step-by-step explanation:

The complete exercise is: "<em>
If 
is a factor of 
, where b is a constant, what is the value of b?</em>
"</h3><h3 />
You know that a factor of the given polynomial is:
Then, in order to find the value of "b", which is a constant of the polynomial, you need to follow these steps:
1. You must rewrite the polynomial as:
2. Now you must substitute 
into the polynomial:
3. Since 2 is a zero of the polynomial, you can substitute 
:
4. Finally, you must solve for the constant "b" to find its value. Then, this is:
3(20)=60
2(20)=40
1(2)=2
3(15)=45
2(20)=40
1(17)=17
3(10)=30
2(30)=60
1(12)=12
3(27)=81
2(10)=20
1(1)=1
3(9)=27
2(18)=36
1(39)=39
Answer:
this question is not complete. need another equation
Step-by-step explanation:
give another equation then I can solve
Hi there!
The correct answer is 6.25 times.
This is how you get there:
1) First off, you are going to need to have the same unit (either cm or mm). I used millimeters for this problem. 25cm=250mm
2) This next part is very easy to get wrong. You need to figure out what you are dividing, and by what. Simply look at the problem. <span><em>"How much longer is the guinea pig than her fish?" </em>This shows what numbers you should be getting. The guinea pig is 250mm long, where the fish is only 40. This means that her guinea pig should be larger. 250÷40=6.25
If you did this problem the other way, you would've ended up with .16. If you put the sizes into perspective, you will notice that this is highly unlikely.
I hope that I have been able to simplify this problem for you!
