Answer:
B (second graph from left)
Step-by-step explanation:
The function when x=0 will be 1 since any number to the zero exponent is 1. This means only B and D are options.
Because of the fraction, the values will be smaller and have a gentler slope. B is the solution.
Answer:
the fee at bank A will be more than the fee at bank D only when the checking account balance is more than $400 dollars.
Step-by-step explanation:
To know the answer to this we work our way backwards.
First we'll have a proportion since we know Jiayi ended up with 75 markers and the ratio of Stanley's markers to Jiayi's is now 2:3. We let the number of Stanley's markers at the end be denoted by x and solve the proportion:
We know that Stanley had 50 markers by the end, and since he let Jiayi borrow 50 markers, then he should've had 100 markers at the start.
ANSWER: Stanley started with 100 markers.
