1.93x3=5.79 but were not done because you need to add tax. So simply multiply 5.79 by 0.5 which equals .2895 round to the nearest cent so .29 then add .29 to 5.79 6.08.
The .05 is the tax % because you always have to remember that a tax % out of 100 is . then whatever % if it's a single number like 1 or 2 then it's like.01 or .02 hen multiply by the full amount. But that isn't the final answer because that is the tax amount. So add it back to the full number. That's how I found the answer.
The answer is 6.08
<u>Answer:</u>
A) There are two complex solutions.
<u>Step-by-step explanation:</u>
To know how many solutions a quadratic equation has, calculate the discriminant of the equation.
discriminant = b² - 4ac
where a = coefficient of x²
b = coefficient of x
c = constant of equation
if b² - 4ac > 0 , then equation has 2 real roots
if b² - 4ac = 0 , then equation has 1 real, repeated root
if b² - 4ac < 0 , then equation has 2 complex roots
In this case, discriminant = 9² - 4(-2)(-12)
= -15
As -15 < 0, equation has 2 complex roots.
