Answer:
(21, 2 )
Step-by-step explanation:
Given the 2 equations
y = - x + 9 → (1)
y = x - 12 → (2)
Substitute (2) into (1)
x - 12 = - x + 9 ( add x to both sides )
x - 12 = 9 ( add 12 to both sides )
x = 21
Substitute x = 21 into either of the 2 equations and evaluate for y
Substituting into (2)
y = × 21 - 12 = 14 - 12 = 2
Solution is (21, 2 )
Answer:
5. 49, (x+7)²
6. 36, (x-6)²
7. 81/4, [x-(9/2)]²
Step-by-step explanation:
5. x² + 2(x)(7) + 7² = (x + 7)²
6. x² - 2(x)(6) + 6² = (x - 6)²
7. x² - 2(x)(9/2) + (9/2)² = (x - 9/2)²
