The first one is y=4x+-11. The second one is y=-5/2x+2
Answer:

Step-by-step explanation:
we know that
The equation of a exponential growth function is equal to

where
P is the population
t is the time in years
a is the initial value
r is the rate of change
<u><em>Looking at the table</em></u>
For t=0
The value of P=1,000
so
substitute the value of the ordered pair (0,1,000) in the exponential equation

The initial value is a=1,000
substitute

For t=1
The value of P=1,400
so
substitute the value of the ordered pair (1,1,400) in the exponential equation

therefore
The exponential equation is

4x+4(3)+4(2)=y
4x+20=y
X equals the amount it cost for each ticket which is unknown. Y equals the total cost. Because the amount of the food is provided, it can be calculated unlike the tickets which is just left at 4x. The work for the snacks are upwards. Its mostly substitution.
