Answer:
y = −3/2x + 8
Step-by-step explanation:
Answer:
x = 9 + 6i or x = 9 - 6i
Step-by-step explanation:
x² - 18x + 117 = 0
Complete the square and solve:
(x - 9)² - 81 + 117 = 0
(x - 9)² + 36 = 0
(x - 9)² = -36
x - 9 = ±sqrt(-36)
x - 9 = ±sqrt(-1).sqrt(36)
i = imaginary number = sqrt(-1)
x - 9 = ±6i
x = 9 ± 6i
There are no real solutions, only imaginary ones
9 + 6i and 9 - 6i
Here's a graph of those terms.
Answer:
b= 17
Step-by-step explanation:
b - 6 = 11
Add 6 to each side
b-6+6 = 11+6
b = 17
