Answer:
y = 4x - 1
Step-by-step explanation:
Equation y = 4x - 1 matches the function described in the table.
I am guessing that the correct form of equation
is:
f(x)
= 16,800(0.9)^x
where
x is the exponent of (0.9)
Since
we are looking for the original population and x stand sfor the number of years,
therefore x=0
substituting:
f(x) = 16,800(0.9)^0
Since (0.9)^0 would just be equal to 1. Therefore
the original population is
16,800.
Answer: B. 16,800
First you had to switch sides of equation.
Then you divide by two from both sides of equation form.
Simplify.
Next, subtract by i from both sides of equation form.
Finally, simplify by equation.
Final answer: 
Hope this helps!

Answer:
it is A
Step-by-step explanation:the red color is to subtract or negative value and the blue one is for addition or positive value
-x^2-2x+4 the first row
-(x^2+2x+1) for the second row or (-x^2-2x-1) is the same
put it together
-2x^2-4x+3
Answer:
-2.5
Step-by-step explanation:
The slope of a line can be found by dividing the rise over the run between two points. The rise is the difference between the y-values, and the run is the difference between the x-values. For both, the value with the greater x-value comes first as you are seeing how much it has changed from the first value to the the other.
Let's use the first two points to find the slope: (0,9), (2,4)
(2,4) has the greater x-value, so the rise between the points would be -5, as 4 - 9 = -5
The run would be 2, as 2-0 = 2.
Therefore the slope would be: -5/2 = -2.5
Hope this helped!
