Answer: -6
Step-by-step explanation:u can do keep change switch which u do the expression to -12+(-3)+9
I think the answer is y = -5/2x - 1, I'm doing the test right now.
Answer:
It just means that it is not equal to each other so the equation is false.
Step-by-step explanation:
The equal sign with a line through it means that they aren't the same. -12 is a different number from 12 so they can't end up being the same in the end of the equation.
Hope this helps!
Answer:
n/(n+1) . . . . n ≠ 1
Step-by-step explanation:
As written, there is no product. There is ony the sum ...
![4\dfrac{n}{4}-4n-\dfrac{1}{n}+1](https://tex.z-dn.net/?f=4%5Cdfrac%7Bn%7D%7B4%7D-4n-%5Cdfrac%7B1%7D%7Bn%7D%2B1)
With appropriate parentheses, this becomes the product of rational functions ...
... (4n)/(4n-4)·(n-1)/(n+1)
![=\dfrac{4n(n-1)}{4(n-1)(n+1)}=\dfrac{n}{n+1}](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B4n%28n-1%29%7D%7B4%28n-1%29%28n%2B1%29%7D%3D%5Cdfrac%7Bn%7D%7Bn%2B1%7D)
_____
At n=1, the product has a "hole" where the denominator of the original expression is zero, so the expression is undefined. Hence the domain of the product must be restricted to n≠1 (as well as n≠-1).
Answer:
A. Trinomial
Step-by-step explanation:
It says it's a polynomial and that based on the number of terms. So right then you can cancel out cubic and quadratic because they aren't polynomials. Also:
Cubic is just a variable with the exponent of 3. Examples:
![x^3,y^3,z^3](https://tex.z-dn.net/?f=x%5E3%2Cy%5E3%2Cz%5E3)
Binomial is a polynomial with 2 terms. Examples:
![5x+3; 6x+2; x+7](https://tex.z-dn.net/?f=5x%2B3%3B%206x%2B2%3B%20x%2B7)
A quadratic has a division sign.
