Answer:

Option B.

Step-by-step explanation:

We have the following polynomial: -10x^2+12x-9=0

Multiplying by -1:

10x^2-12x+9=0

Using the quadratic formula, we find that the roots are:

0.6 ± 3√(6)/10i

Therefore, the correct answer is B.

Michael and Lindsey are saving money. Michael begins with $20 and saves $5 per week. Lindsey begins with no money, but saves $10
True [87]
Let
x----------> number of weeks
y----------> saved money

we now that

<span>Michael begins with $20 and saves $5 per week
so
y=20+5x------> equation 1

and
</span><span>Lindsey begins with no money, but saves $10 per week
</span><span>y=10x-------> equation 2

</span><span>the number of weeks it will take for Lindsey and Michael to save the same amount of money is when equation 1 is equals to equation 2
</span>
therefore
20+5x=10x------> 10x-5x=20------> 5x=20-----> x=20/5-----> x=4 weeks

the answer is 
4 weeks
