Answer:
b)
Step-by-step explanation:
n²+n-42=0
Using mid-term break
n²+7n-6n-42=0
n(n+7)-6(n+7)=0
(n-6)(n+7)=0
Either,
n-6=0 OR n+7=0
n=6 OR n= -7

Answer:
(- 1, 1 )
Step-by-step explanation:
Given the 2 equations
y = 3x + 4 → (1)
y = x + 2 → (2)
Substitute y = 3x + 4 into (2)
3x + 4 = x + 2 ( subtract x from both sides )
2x + 4 = 2 ( subtract 4 from both sides )
2x = - 2 ( divide both sides by 2 )
x = - 1
Substitute x = - 1 into either of the 2 equations and evaluate for y
Substituting x = - 1 into (2)
y = - 1 + 2 = 1
Solution is (- 1, 1 )
