Factored form: y = -3x(4x - 11)
<span>The equation given is f(x) = x^2 - 12x + 27
</span>
Based on its form, it is a parabola. First, factor the quadratic equation:
f(x) = (x-9) (x-3)
Plot in the x-y plane, assign values of x and solve for the values of y.

Answer:
he makes $112.50
Step-by-step explanation:
first you have to find out how much he makes before tax is taken out. all you do is multiply 12.50 by 30, which gives you $375.00. then, you can either put in the calculator 30%375 or 0.3×375(both are the same thing) and you should get $112.50
Angles 6 and 7 are vertical angles
