Solve the inequality y^2-3y greater than 18 sorry couldn't find the greater than sign
2 answers:
Answer:
The greater than sign (on my computer) is above the period key. So, just jit SHIFT then type the period key.
So, I guess you want to solve y^2 -3y > 18
We can factor that as y * (y -3) > 18
Well, if it is
y^2 -3y -18 = 0 then
Then y = 6 and y = -3
Hope that helps
Step-by-step explanation:
Answer:
y > 6 or y < -3
Step-by-step explanation:
y² - 3y > 18
Complete the square.
y² - 3y + 9/4 > 18 + 9/4
y² - 3y + 9/4 > 81/4
(y - 3/2)² > 81/4
y - 3/2 > 9/2, or y - 3/2 < -9/2
y > 6 or y < -3
