Well the formula for the quadratic equation is y = -b <u>+</u><span> √b² - 4ac / 2a
</span>Fill in the variables with the information where a = 2, b = 2, and c = -12. 

The final answer is <span>y = -2 +</span><span> </span><span><span>√2² - 4(2)(-12) / 2(2)
</span>A simplified answer would be <span>y = -2 <u>+</u> </span></span><span>√4 + 96 / 4, which further simplifies to 
</span>y = -2 <u>+</u> 10 / 4

This can be simplified into two answers, either y = -3 or y = 2

At an electronics store, a $165 television is marked up 110%. Dave purchases the TV and must pay 6.5% sales tax. What is his fin
Mariana [72]
Firstly, we need to know the price of the TV after the 110$ increase.
     $165 x 1.10 = $181.50
[This is an increase of $16.50]
[1.10 is the equivalent of 110%. 1 being 100% and the .10 being 10%]

Now for the sales tax. We apply a similar method.
     $181.50 x 0.065 = $11.79
     6.5% of $181.50 is $11.79, so we add the two together to find the final cost.

The final cost of the TV is $193.29
