The answer is b, I’m not saying it’s true but just predicting xoxoox
Answer:
x=40.25
Step-by-step explanation:
Answer:
- -6x² - 6 = -7x - 9
- -6x² + 7x - 6 + 9 = 0
- -6x² + 7x + 3 = 0
- 6x² - 7x - 3 = 0
<u>Discriminant:</u>
- D = (-7)² - 4*6*(-3) = 49 + 72 = 121
<u>Since D > 0, there are 2 real solutions:</u>
- x = (- (-7) ±√121 )/12
- x = (7 ± 11)/12
- x = 1.5, x = -1/3
5 · 5 - 4 · 4 = 9 sorry if I'm wrong
the dots mean to multiply
