The x has an exponent of 2. the exponent of 2 means x squared, which is x•x. this isn't the same as x+x, because x+x=2x whereas x•x=x squared.
Set 5x=3x+50 because they are alternate exterior angles. Solve for x and you should get x=25
Next step, plug in the x value for 5x. So 5*25=125. Set y+12=125 since they are vertical angles which are congruent. Solve for y and you get y=113

Answer:
$5,956.2
Step-by-step explanation:
First we need to find the amount after 5years using the formula
A =P(1+r)^n
A = 9000(1+0.06)^5
A = 9000(1.06)^5
A = 9000(1.3382)
A = 12,043.8
Interest after 5 years = 12,043.8 - 9000
Interest after 5 years = 3,043.8
Since it will be worth 6% less each year, the amount after 5years will be 9000 - 3,043.8 = $5,956.2
