Answer:
The exact value of tan(60°) is √(3).
Step-by-step explanation:
Answer:
unsolvable because the second equation is just -2.5 times the first equation.
Step-by-step explanation:
2x-6y=12 then 2x=12+6y x=6+3y
-5x+15y=-30
substitute x
-5(6+3y)+15y=-30
-30-15y+15y=-30
y=y
Given:
The polynomial is:
![-5x^3y^3+8x^4y^2-xy^5-2x^2y^4+8x^6+3x^2y^4-6xy^5](https://tex.z-dn.net/?f=-5x%5E3y%5E3%2B8x%5E4y%5E2-xy%5E5-2x%5E2y%5E4%2B8x%5E6%2B3x%5E2y%5E4-6xy%5E5)
To find:
The simplified form of the given polynomial in standard form.
Solution:
We have,
![-5x^3y^3+8x^4y^2-xy^5-2x^2y^4+8x^6+3x^2y^4-6xy^5](https://tex.z-dn.net/?f=-5x%5E3y%5E3%2B8x%5E4y%5E2-xy%5E5-2x%5E2y%5E4%2B8x%5E6%2B3x%5E2y%5E4-6xy%5E5)
Combining the like terms, we get
![=-5x^3y^3+8x^4y^2+(-2x^2y^4+3x^2y^4)+8x^6+(-xy^5-6xy^5)](https://tex.z-dn.net/?f=%3D-5x%5E3y%5E3%2B8x%5E4y%5E2%2B%28-2x%5E2y%5E4%2B3x%5E2y%5E4%29%2B8x%5E6%2B%28-xy%5E5-6xy%5E5%29)
![=-5x^3y^3+8x^4y^2+x^2y^4+8x^6-7xy^5](https://tex.z-dn.net/?f=%3D-5x%5E3y%5E3%2B8x%5E4y%5E2%2Bx%5E2y%5E4%2B8x%5E6-7xy%5E5)
Now, rewrite this polynomial in standard form.
![=8x^6+8x^4y^2-5x^3y^3+x^2y^4-7xy^5](https://tex.z-dn.net/?f=%3D8x%5E6%2B8x%5E4y%5E2-5x%5E3y%5E3%2Bx%5E2y%5E4-7xy%5E5)
Therefore, the required polynomial in standard form is
.
