Answer:
You are paying 65% of the original price.
Step-by-step explanation:
So what I did is trial and error by 5 so I started with 75% and then 70% and so on until 65%
To solve the average rate of change, use the formula of the slope:
m = ( y2 - y1 ) / ( x2 - x1 )
but first we must solve the value of the function when x = 3
f(3) = - log ( 4 * 3 ) + 5
f (3) = 3.92
solve the function when x = 8
f(8) = - log ( 4 * 8) + 5
f(8) = 3.49
so the average rate of change
m = ( 3.49 - 3.92 ) / ( 8 - 3)
m = - 0.09
Y - y1 = m (x - x1)
m = 4 , x1 = 1 and y1 = 3, so its
y - 3 = 4(x - 1)
Answer:

Step-by-step explanation:
the 6th power of 10 would be 10^6, then you'd multiply it by 3 which would make it 10^6*3
you could then simplify it and say 10^18 (multiply the exponents [6 and 3])
Answer:
x = c - a / -b
Step-by-step explanation:
a - bx = c
-a -a
-bx = c - a
divide -b
x = c - a / -b
