Multiple Choice

Read each question. Then write the letter of the correct answer on your paper.

1. Which equation is equivalent to x 2 + 24 x + 100 = − 46 ? x squared , plus 24 x plus 100 equals negative 46 question mark
   1. ( x + 12 ) 2 = − 2 open x plus 12 , close squared , equals negative 2
   2. ( x − 12 ) 2 = − 2 open x minus 12 , close squared , equals negative 2
   3. ( x − 12 ) 2 = 2 open x minus 12 , close squared , equals 2
   4. ( x + 12 ) 2 = 2 open x plus 12 , close squared , equals 2

2. What is the solution of the following system of equations? { x + y + z = 13 2 x − y = 4 x + z = − 3 left brace . table with 3 rows and 1 column , row1 column 1 , x plus y plus z equals 13 , row2 column 1 , 2 x minus y equals 4 , row3 column 1 , x plus z equals negative 3 , end table

   6. x = 10 , y = 16 , z = 13 x equals 10 comma y equals 16 comma z equals 13
   7. x = 16 , y = 28 , z = − 19 x equals 16 comma y equals 28 comma z equals negative 19
   8. x = 10 , y = 16 , z = − 13 x equals 10 comma y equals 16 comma z equals negative 13
   9. x = − 16 , y = − 28 , z = 19 x equals negative 16 comma y equals negative 28 comma z equals 19
