f(x) = sin(x)
Domain (–∞, ∞)
Range [–1, 1]
y = arcsine(x)
y = f–¹(x)
Domain [–1, 1]
Range [–π/2, π/2]
Answer:
40+99
139
Step-by-step explanation:
y= 1.25x+6.75
Make 31.75 y because that is the total cost he paid.
1.25x+6.75=31.75
1.25x=25
x=20
So he had 20 refills.
3,300-500=2,800
2,800+ 950=3,750
3750-60= 36,900
36,900-225= 36,675
