Answer:
Step-by-step explanation:
Supplementary angles sum to 180 degrees.
x+118=180
x=62 degrees
B. 361/4
you get: x^2-19x+361/4=(x-19/2)^2
Answer: -3
Step-by-step explanation:
18/6 = 3
18/-6 = -3

Answer:
5. f(x) = 10,000 (1.5)^x
Step-by-step explanation:
We would have to multiply the original amount by 1.50^x because the initial amount would be 1, and 50% increase would be .5 so 1.5 and you raise it to the number of years to show the total increase.
Let's test it.
Initial:
10,000
After 1 year
10,000 + (.5*10000)
10,000 + 5000 = 15,000
After 2 years
15,000 + (.5*15000)
15,000 + 7500 = 22,500
Let's try our equation.
f(x) = 10,000 (1.5)^x
x = 2
10,000(1.5)^2
10,000(2.25) = 22,500
The same!
