Answer:
$39,851.25
Step-by-step explanation:
If the sales increase at a rate of 9% per year, this means it will be 109% of the previous year's value since 100% + 9% = 109%
109% in decimal form = 109/100 = 1.09
Therefore, the exponential function is:
, where 
is the number of years
So when 
,
After 8 years, annual sales = $39,851.25
Answer: 4
Step-by-step explanation:
7-3=4
Answer:
The answer is B
Step-by-step explanation: After solving this equation using y=mx+b
I got y=-4x+7
So they give us the slope which is negative 4
so you would throw in the x coordinate with the slope and multiply to get y=-12+7
then you would use the y coordinate to substitute the Y
-5=-12+7
i add twelve on both sides and end up with the y intercept being 7]
so I add them into the equation and got y=-4x+7
Two lines are "inconsistent" if they are parallel. They are "equivalent" if they are the same line. Otherwise, they are "consistent."
Your first 3 graphs show "consistent" equations.
The 4th graph shows "inconsistent" equations.
The solution shown on the 5th graph is where the lines intersect, near point
(5, 3)
