Answer: $428.00
Step-by-step explanation: First, we need to calculate the person’s total hours, (30 x 2 = 60 hours) then the money per hour (60 x 9) then take away the taxes and account deductions.
False I think I don't know
Ax²+bx+c=0 , a>0, c<0 (or a<0, c>0)
D=b²-4ac ≥ 0 always will be positive
because negative*positive = negative,
a*c -negative, so (-4ac) positive
So,
<span>If, in a quadratic equation, the values of a and c have opposite signs, the solutions of the equation are real numbers.
</span>True
