Answer:
Step-by-step explanation:
We can use the quadratic formula or factor, This looks hard to factor so we should use the quadratic formula.
ax^2 + bx + c
so
a=4
b=-9
c=2
you can try it by hand or use this:

you get x=2 and x=0.25 these are the x intercepts (where Y is zero and where the graph crosses the x axis)
so mark x=2 and x=0.25 with a dot on a number line and you can draw a straight line between them since that is the part of the graph that is below the x axis (because the equation has <0) it is a positive parabola because the "a" value is positive and the presence of a "b" value means part of the graph will be below the x axis
Answer:
$12,000
Step-by-step explanation:
Since the answer to problem 2 is $8,000 and it is 2/3 of 30 years, all you have to do is find half of $8,000, which is $4,000 and add them together which makes $12,000 and it pays off for 30 years.
