Let's create a table, and use arbitrary values of x between -3 and 3 (if the solution is not in this interval, we can use another one later). If we call:
We want to find the x's for with f(x) = 0
This is the table:
And now we can evaluate f(x) in each value of x to complete the table:
The table is:
If we use this values and plot them in the cartesian plane.
We get:
And now if we plot a line that connects the points, we get the graph of the quadratic equation:
Since the problem ask us to find the value of x for which f(x) = 0, we can see both in the table and in the graph that this value is x = 2
The answer is $337.50 paid. We would change 7 1/2% (7.5%) to its decimal form which is .075. Then we would multiply that by $4,500 which would get $337.5 or $337.50 which is the same thing. Hope this helped!

Answer:
For problem 17a) your answer is: x=11.5 degrees
Step-by-step explanation:
1. Measure of angle BCA will be 180°-124°=46°
2. In triangle BCA, you now have two angles. 46 degrees, and 2x.
3. Measure of angle ABE is an exterior angle of triangle BCA
4. Using the exterior angle theorem, angle ABE=angle BCA+angle BAC
5. substitute!! 2x+46=6x
6. move 2x over and then divide by 4, you get x=11.5°
7. You can plug the answer back in to check if it correct!! have a nice day :>
