1 answer:
Answer:
x intercept: 5
y intercept: 50
Step-by-step explanation:
- let us plot the graph for better understanding.
- we will represent f(x) on y-axis so, the equation will become: y= 50-10x
- the equation is of the form : y=mx+c
[where, m: slope of the line
c : y-intercept ]
- meaning of x intercept: the x-coordinate of the point where the line meets x-axis
- meaning of y intercept: the y-coordinate of the point where the line meets y-axis
- the line y= 50-10x has slope of -10 and it passes through (0,50)
[ (0,50) lies on the line only. substitute and check if the point satisfies the above line equation]
- by seeing the graph in the attachment and by the definitions given above, we can say that,
x intercept: 5
y intercept: 50

Answer:
1st problem: b)
2nd problem: c)
Step-by-step explanation:
1st problem:
The formula/equation you want to use is:
where
t=number of years
A=amount he will owe in t years
P=principal (initial amount)
r=rate
n=number of times the interest is compounded per year t.
We are given:
P=2500
r=12%=.12
n=12 (since there are 12 months in a year and the interest is being compounded per month)
Time to clean up the inside of the ( ).
----------------------------------------------------
2nd Problem:
Compounded continuously problems use base as e.
P is still the principal
r is still the rate
t is still the number of years
A is still the amount.
You are given:
P=2500
r=12%=.12
Let's plug that information in:
