Infinite solution
Answer:
y = 4
Step-by-step explanation:
An exponential function in standard form is
y = a 
Use ordered pairs from the table to find a and b
Using (0, 4), then
4 = a 
( note that = 1 ), so
a = 4, then
y = 4
Using (1, 8)
8 = 4 
= 4b ( divide both sides by 4 )
b = 2
y = 4 ← represents the values in the table
D = vt
Distance traveled by train
d = 55t
Distance traveled by plane
d = 285t
Total distance
d = 1020
So, you do:
distance traveled by plane + distance traveled by train = total distance
(55t) + (285t) = 1020
Solve for t
t = 3 hours
t is the time traveled by each so 3 hrs traveled by train and 3 hrs traveled by plane
Total time = 3 + 3 = 6 hours
Answer:
840 courses
Step-by-step explanation:
One third of the people ate a two course meal: 105 people ate two course meals.
Two thirds of the people ate a three course meal: 210 people ate three course meals.
105X2 + 210X3 = 210 + 630 = 840 courses
