Worksheet 10 of 10 (100% complete)

Question 1

Question: What is the value of xy? Statement (1): x + y = 7 Statement (2): x² + y² = 25

Using (x+y)² = x² + 2xy + y² → 49 = 25 + 2xy → 2xy = 24 → xy = 12.

Question 2

Question: What is the value of xy? Statement (1): x + y = 7 Statement (2): x² + y² = 25

Using (x+y)² = x² + 2xy + y² → 49 = 25 + 2xy → 2xy = 24 → xy = 12.

Question 3

Question: What is the value of xy? Statement (1): x + y = 7 Statement (2): x² + y² = 25

Using (x+y)² = x² + 2xy + y² → 49 = 25 + 2xy → 2xy = 24 → xy = 12.

Question 4

Question: What is the value of xy? Statement (1): x + y = 7 Statement (2): x² + y² = 25

Using (x+y)² = x² + 2xy + y² → 49 = 25 + 2xy → 2xy = 24 → xy = 12.

Question 5

Question: What is the value of x + y? Statement (1): 2x + 3y = 12 Statement (2): 4x + 6y = 24

Statement (2) is just 2 times statement (1). Both represent the same line, infinite solutions. Cannot determine unique x + y.

Question 6

Question: What is the value of x? Statement (1): x + 2y = 8 Statement (2): 2x + 4y = 16

Statement (2) is 2 times statement (1). Both represent same equation. Infinite solutions for x.

Question 7

Question: What is the value of x? Statement (1): x + y = 10 Statement (2): x - y = 4

Adding equations: 2x = 14 → x = 7. Subtracting: 2y = 6 → y = 3. Both statements needed.

Question 8

Question: What is the value of x + y? Statement (1): 2x + 3y = 12 Statement (2): 4x + 6y = 24

Statement (2) is just 2 times statement (1). Both represent the same line, infinite solutions. Cannot determine unique x + y.

Question 9

Question: What is the value of x² - y²? Statement (1): x - y = 3 Statement (2): x + y = 7

x² - y² = (x-y)(x+y) = 3 × 7 = 21.

Question 10

Question: What is the value of x + y? Statement (1): 2x + 3y = 12 Statement (2): 4x + 6y = 24

Statement (2) is just 2 times statement (1). Both represent the same line, infinite solutions. Cannot determine unique x + y.

Question 11

Question: What is the value of x? Statement (1): x + y = 10 Statement (2): x - y = 4

Adding equations: 2x = 14 → x = 7. Subtracting: 2y = 6 → y = 3. Both statements needed.

Question 12

Question: What is the value of x² - y²? Statement (1): x - y = 3 Statement (2): x + y = 7

x² - y² = (x-y)(x+y) = 3 × 7 = 21.

Question 13

Question: What is the value of x + y? Statement (1): 2x + 3y = 12 Statement (2): 4x + 6y = 24

Statement (2) is just 2 times statement (1). Both represent the same line, infinite solutions. Cannot determine unique x + y.

Question 14

Question: What is the value of x? Statement (1): x + y = 10 Statement (2): x - y = 4

Adding equations: 2x = 14 → x = 7. Subtracting: 2y = 6 → y = 3. Both statements needed.

Question 15

Question: What is the value of x? Statement (1): x + y = 10 Statement (2): x - y = 4

Adding equations: 2x = 14 → x = 7. Subtracting: 2y = 6 → y = 3. Both statements needed.

Question 16

Question: What is the value of x² - y²? Statement (1): x - y = 3 Statement (2): x + y = 7

x² - y² = (x-y)(x+y) = 3 × 7 = 21.

Question 17
