Answer:
200
Step-by-step explanation:
-2/5=4-2x/5
-4 2/5=-2x/5
-22=-2x
x=11
Are you sure that y=4-2x/5 is the equation
Your answer would be (6,20), because both lines pass through this point.
If you graph the two functions, you will see that this is the point at which they intersect each other.
Hope this helps! :)
Answer:
(x-3)(x-2)
Step-by-step explanation:
x^2-5x+6
x^2-2x-3x+6
x(x-2)-3(x-2)
(x-3)(x-2)
The decay factor for the annual rate of change of - 55 % is 0.45.
A quantity must vary by a specific percentage each time period in order for growth or decay to be exponential.
With the function displayed to the right, you may represent exponential growth or decay.
A(x) = a( 1 + r)ˣ
Where A is the amount after x time periods, a is the initial amount, x is the number of time periods, and r is the rate of change.
Now, we have the annual rate of change as:
r = - 55 % = - 55 / 100 = - 0.55
From the function A(x) = a( 1 + r)ˣ , the corresponding factor is 1 + r.
So, let B = 1 + r
B = 1 + r
B = 1 + (- 0.55)
B = 1 - 0.55
B = 0.45
Now, the value of B is less than 1 therefore, the corresponding decay factor is 0.45.
