Answer:
Step-by-step explanation:
3x² - 3x + 7 = 0
a = 3 ; b = -3 and c = 7
D = b² - 4ac = (-3)² - 4*3*7
D = 9 - 84 = - 75
D = 75i²
√D = √75i² = 
Substitute the values of x from each table and see which values fit
For example in table d when x = 40 y = (-3/8)*40 + 75 = 60 which is the result given in table d
The other 2 values also fit table d
Answer is table d.
I think you mean mixed number fractions. So what you do is just subtract, both the fraction and also the number. So for example 1 2/3 - 1 1/3 is just 1/3 because you subtracted both of them
