We'll be assuming this is with simple interest.
now, a year has 12 months, thus in 18 months there are 18/12 years.
THE ANSWER IS THE SECOND AND THIRD CHOICE.
The reflection across y axis of (x,y) would be (-x,y)
thus the answer is b
Please take the above picture for reference
hope it helps!
Answer:
a = 0.5 or 1/2
b = 19/4 or 4.75
Step-by-step explanation:
Step 1: Isolate <em>x</em>'s
x² - x = -5
Step 2: Complete the Square
x² - x + 1/4 = -5 + 1/4
(x - 1/2)² = -19/4
Step 3: Move everything to one side
(x - 0.5)² + 4.75
