Answer:
The answer to your question is r = 10
Step-by-step explanation:
Data
(x² + 10x ) + (y² - 8y ) = 59
Process
1.- Complete the perfect square trinomials
(x² + 10x + (5)²) + (y² - 8y + (4)²) = 59 + (5)² + (4)²
2.- Simplify
(x² + 10x + 25) + (y² - 8y + 16) = 59 + 25 + 16
3.- Factor
(x + 5)² + (y - 4)² = 100
or (x + 5)² + (y - 4)² = 10²
4.- Compare the result with the standard form
(x - h)² + (y - k)² = r²
then r² = 10²
and r = 10

Answer:
9x - 2x + 62 = 9x + 24
Number of correct answer each obtained = 19
Step-by-step explanation:
Given that:
Number of correct answers = x
POINTS for correct answers = 9
POINTS for incorrect answers = - 2
SCHOOL A:
Number of correct answers = x
Number of incorrect answers = x
Initial point = 62
Initial point + 9(number of correct answers) + - 2(number of incorrect answers)
62 + 9x - 2x
SCHOOL B :
Number of correct answers = x
Number of incorrect answers = 0
Initial point = 24
Initial point + 9(number of correct answers) + - 2(number of incorrect answers
24 + 9x
Since they end up tied :
School A = School B
62 + 9x - 2x = 24 + 9x
9x - 2x + 62 = 9x + 24
Number of correct answers gotten :
9x - 2x + 62 = 9x + 24
7x + 62 = 9x + 24
7x - 9x = 24 - 62
-2x = - 38
x = 19
Hence, Number of correct answers each obtained = 19
