B is correct because when you plug in x=0 into the equation, you get 5.
This means that the y intercept is five.
Here's why the other answer choices are wrong:
The graph is actually INCREASING.
x can be NEGATIVE.
Not all exponential graphs has a y intercept of ONE.
Have an awesome day!
Answer:
y =2.5
Step-by-step explanation:
1.4y = 3.5

1.4y /1.4 = 3.5/1.4
y =2.5
Think of it this way. Ignore for now that $100 was stolen.
The purchase of the $70 item for $100 cash with $30 change is a perfectly fair purchase. The store received $100 cash, and the store gave $70 worth of merchandise plus $30 cash.There was no loss to the store there.
The fact that $100 in cash was stolen earlier from cash register means the loss is $100. The legitimate transaction does not affect the loss.
If you have a hard time understanding the loss is $100, then think of it this way.
Reverse the order of the two happenings.
A person walked into a store and bought a $70 item with a $100 bill. He received $30 change. So far, there is no loss to the store. Everything is legit.
That customer later came back to the store and stole $100 from the cash register.
Here we see clearly that the loss is exactly $100. It is simply the $100 stolen from the cash register.
Use the compound amount formula:
A = P*(1+r/n)^(nt)
Here,
A = $3500*(1+0.0375/12)^(12*12) = $5485.24
