Answer:
h = -t+20
After 8 hours the candle will be 12 inches
Step-by-step explanation:
We have 2 points (time, inches)
(3,17) and (5,15)
We can find the slope
m = (y2-y1)/(x2-x1)
= (15-17)/(5-3)
= -2/2
= -1
We can use point slope form
y-y1 = m(x-x1)
Replace y with h and x with t
h-17 = -1 (t-3)
Distribute
h-17 = -t+3
Add 17 to each side
h-17+17 = -t+3+17
h = -t+20
After 8 hours
h = -t+20
h = -8+20
h= 12
Answer:
50 student
350 adult
Step-by-step explanation:
x=# student tickets
y=#adult tickets
x+y=400 2x+3y=1050
x=400-y 2(400-y)+3y=1050
800-2y+3y=1050
y=350
x=400-350
x=50
