As the y intercept lies on the x-axis, x=0
To find the y-intercept, put x=0 into the equation:
Therefore,the y-intercept=9.
Hope it helps!
Answer:
No. 5x and 5x² are not like terms.
When a variable is raised to two different powers, they can not be added together.
Another way to look at it is to note that:
5x + 5x² ≡ 5x(1 + x)
It is more obvious there that 1 and x are not like terms, thus neither are 5x and 5x², though they do have common factors.
Answer:
your answer is .17. 2/12 on a calculator gets you .166 repeating,

Answer:
The answer is 2root5 or C
Step-by-step explanation:
The square root of 20 is 4.472135... so, you have to solve what of your possible solutions could be the right answer (it's best to use a graphing calculator). We already know it not A, so that's off the list because the square root of 20 is already greater than 4. We then move onto C or 2root5 which we also get 4.472135... (by doing 2 * the square root of 5). We then move onto B and find that 5root2 is 7.07 (by multiplying 5 by the square root of 2). So B is off the plate. Lastly, is 20 = to the square root of 20. No, we already established that in the beginning of the problem. So, overall the answer is C or 2root5.
