Answer:
y=370,000(1.091)^t
Step-by-step explanation:
The formula for exponential growth is;
y=a(1+r)^x
where
y=future growth
a= initial population
r=growth rate as a decimal
x=number of time interval that have passed
Given;
a=370,000
r=9.1% =0.091
x=t
Thus
y=370,000(1+0.091)^t
y=370,000(1.091)^t
Answer: (x, y) = ( -2, -3 )
=============================================
Work Shown:
2x+y = -7
2( x ) + y = -7
2( 4+2y ) + y = -7 .... plug in x = 4+2y
2*4 + 2*2y + y = -7
8 + 4y + y = -7
5y+8 = -7
5y = -7-8 .... subtract 8 from both sides
5y = -15
y = -15/5 ... divide both sides by 5
y = -3
This y value pairs with...
x = 4 + 2y
x = 4 + 2(-3)
x = 4 - 6
x = -2
So we have (x, y) = (-2, -3) as the solution to the system.
