Step-by-step explanation:
Answer:
x = 0
Easy peasy! If the answer is 0 from that algebraic expression then you can automatically say that the variable x = 0 because you can't add, multiply, or divide any number outside of 0 to get 0. I hope that this helps

Step-by-step explanation:
The answer to the first one would be B. The formula for exponential decay with the filled in values are as follows: 25000(.85)^5 Just plug it into a calculator.
The answer to the second question would also be B. The easiest way to get this answer is to find the slope, or how much the y is changing per change of one in x. In this case you can subtract to find it increases by 3 each time. Subtract three from the y value at one to get the y value at 0 or the y intercept
