Option D: Two irrational solutions

Explanation:

The equation is 17+3 x^{2}=6 x

Subtracting 6x from both sides, we have,

3x^{2} -6x+17=0

Solving the equation using quadratic formula,

x=\frac{6 \pm \sqrt{36-4(3)(17)}}{2(3)}

Simplifying the expression, we get,

\begin{aligned}x &=\frac{6 \pm \sqrt{36-204}}{6} \\&=\frac{6 \pm \sqrt{-168}}{6} \\&=\frac{6 \pm 2 i \sqrt{42}}{6}\end{aligned}

Taking out the common terms and simplifying, we have,

\begin{aligned}x &=\frac{2(3 \pm i \sqrt{42})}{6} \\&=\frac{(3 \pm i \sqrt{42})}{3}\end{aligned}

Dividing by 3, we get,

x=1+i \sqrt{\frac{14}{3}}, x=1-i \sqrt{\frac{14}{3}}

Hence, the equation has two irrational solutions.

What is the value of y in the equation 3(3y − 15) = 0? 5 6 7 9
mezya [45]
Y = 5
3(3y - 15) is also equal to 9y - 45, which means to find y, you have to divide 45 by 9, which is 5.

Two buses leave seattle at the same time and travel in opposite directions. one bus averages 55 mi/h and the other bus averages
nalin [4]

In 4 hours they will be 400 miles apart 4 times 55 is 220 and 4 time 45 is 180 since there going in opposer directions add the miles together and it equals 400 so it takes 4 hours

If QRST below is a rectangle, what is the measure of angle T + angle R?
GenaCL600 [577]
I can't see QRST and I'm wondering how far below it's located.

But I do know that ALL of the angles in EVERY rectangle are
right angles ... 90°  each.

So if QRST is really a rectangle, then any two of its angles
add up to  (2 · 90°)  =  180° .
