Answer:

\large\boxed{-10x^6+5x^5+15x^4-10x^3-6x^2}

Step-by-step explanation:

(5x^5+4x^2-2x^6+6x^4)-(10x^2+10x^3+8x^6-9x^4)\\\\=5x^5+4x^2-2x^6+6x^4-10x^2-10x^3-8x^6-(-9x^4)\\\\=5x^5+4x^2-2x^6+6x^4-10x^2-10x^3-8x^6+9x^4\\\\\text{combine like terms}\\\\=(-2x^6-8x^6)+5x^5+(6x^4+9x^4)-10x^3+(4x^2-10x^2)\\\\=-10x^6+5x^5+15x^4-10x^3-6x^2

Answer:

-10x^6+5x^5+15x^4-10x^3-6x^2.

Step.by-step explanation:

5x^5+4x^2-2x^6+6x^4 -  (10x^2+10x^3+8x^6-9x^4).

First distribute the negative over the parentheses:

=5x^5+4x^2-2x^6+6x^4 - 10x^2-10x^3-8x^6+9x^4

Now bring like terms together:

= -2x^6-8x^6+5x^5+6x^4+9x^4-10x^3+4x^2-10x^2

=  -10x^6+5x^5+ 15x^4-10x^3-6x^2.

The line segment is rotated by 270 degrees counterclockwise about the origin to form C'D'. Which statement describes C'D'? C'D'
Elan Coil [88]

Answer:

  • A. C'D' is 4 units long

Step-by-step explanation:

According to the graph, CD is 5 - 1 = 4 units long.

Rotation doesn't change the length of the segment, so C'D' = CD = 4 units.

Correct choice is A.

What is y=2x^2-12x+16 in vertex form
Natasha2012 [34]

Answer:

y = 2(x-3)^2 - 2

Step-by-step explanation:

y = 2x^2 - 12x + 16

y = 2(x^2 - 6x + 8)

y = 2(x^2 - 6x +8 +1 -1) you "complete the square" by bringing the last term (8) up to "half of the middle co-efficient squared". Middle co-efficient is -6, half is -3, squared is 9. To get from 8 to 9 you must add 1 (+1), but if you add 1 you must subtract 1 (-1) so that you don't change the overall value of inside the bracket


y = 2(x^2 - 6x +9) - 2 (bring the -1 outside of the brackets)

y = 2(x-3)^2 - 2
