I need help really badly please
Stolb23 [73]

Answer:

  y = 26

Step-by-step explanation:

The angles of a linear pair total 180°.

__

  (2y +1)° +(5y -3)° = 180° . . . . the sum of the angles is 180°

  7y -2 = 180 . . . . . . divide by °, collect terms

  7y = 182 . . . . . . . . add 2

  y = 26 . . . . . . . . . divide by 7

_____

<em>Additional comment</em>

The angle measures are (2(26) +1)° = 53°, and (5(26) -3)° = 127°. These total 180°, as they should.

Complete the square x^2+18x+_
kipiarov [429]

Answer:

x^2 + 18x + 81 complete's the square.

Step-by-step explanation:

y = [x^2 + 18x + (18/2)^2 ] - (18/2)^2

y = [x^2 + 18x + 81] - 81

y = (x + 9)^2 - 81 This is just to make the completion of the square accurate.

You can't just add something to an expression. You have to balance it out.
