Plz help solve for x question is in pic

  (x, y) = (5, -3)

Step-by-step explanation:

Apparently, you're asked to solve for x first. This suggests you will be substituting for x in the quadratic. This works, but may make the problem more difficult than it has to be.

Using the found value of x, we have ...

  y = (2 -y)^2 -11(2 -y) +27

  y = 4 -4y +y^2 -22 +11y +27 . . . . eliminate parentheses

  y^2 +6y +9 = 0 . . . . . . . . . . . . . put in standard form

  (y +3)^2 = 0 . . . . . . . . . . . . . . factor

  y = -3 . . . . . . . . . . . . . . . . . the value of y that makes the factor zero

  x = 2 -(-3) = 5

The one solution is (x, y) = (5, -3).

Alternate solution

The two expressions for y can be equated:

  x^2 -11x +27 = -x +2

  x^2 -10x +25 = 0 . . . . . rearrange to standard form

  (x -5)^2 = 0 . . . . . . . . factor

  x = 5 . . . . . . . . . . . x that makes the factors zero

  y = -5 +2 = -3 . . . corresponding value of y

This solution removes the need for the "eliminate parentheses" step in the original solution, so cuts down on the opportunity for error.

sorey if i hav bad engelish im bad engelish

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
