Answer:
The answer to your question is: x1 = - 7 + 9i x2 = -7 - 9i
Step-by-step explanation:
x² + 14x = - 130
x² + 14x + (7)² = -130 + (7)²
(x + 7)² = -81
x + 7 = ± √-81
i² = -1, then x + 7 = ±√ 81i²
x + 7 = ± 9i
x1 = -7 + 9i x2 = -7 - 9i
Let x be the money he had originally.
x/3+5=x/2
5=x/6
x=30
So he had $30 originally.
Answer:
x = y · 11
Step-by-step explanation:
Since x is divided by 4, we have to multiply each side by 4.
x-7=y · 4 To get x by itself, add 7 to each side to get x = y · 11
