Answer:

The equation -x2 + 6x - 9 = 0 has two real solutions.

Step-by-step explanation:

${b}^{2} - 4ac = {6}^{2} - 4( - 1)( - 9) = 0$

The discriminant equals to 0, so the quadratic equation has 1 real solution.

D-1/2=5/12 what is d??

EleoNora [17]

Answer:

d = $\frac{11}{12}$

Step-by-step explanation:

1) To solve for d, isolate it in the equation. So, to get rid of the $-\frac{1}{2}$ with the d, add $\frac{1}{2}$ to both sides.

$d-\frac{1}{2} = \frac{5}{12} \\d - \frac{1}{2} +\frac{1}{2} = \frac{5}{12} + \frac{6}{12} \\d = \frac{11}{12}$

Thus, d = $\frac{11}{12}$ .
