4(2k - 3) + 1 = 8k - 11
8k - 12 + 1 = 8k - 11
8k - 11 = 8k - 11
So, these two equations equal to the same thing.
Glad I could help and gave a fantastic day!
Answer:
b = 30
Step-by-step explanation:
1/4 (8b-80) +b = 70
2b - 20 + b = 70
3b = 90
b = 30
The input to an exponential function is the initial value of the variable.
