y 40 20 8 4
a. Direct variation; y=40x
b. Direct variation; y=(1/40)x
c. Inverse variation; xy=40
d. Inverse variation; xy=1/40
I feel so stupid for not knowing the answer, please explain it to me.
Answer:
To figure out which loan has the lower total cost, we need to calculate the total repayment amount for both loans.
The formula to calculate the monthly payment for a loan is:
P = [r*PV] / [1 - (1 + r)^-n]
where:
P is the monthly payment
r is the monthly interest rate (annual rate / 12)
PV is the present value, i.e., the loan amount
n is the number of payments (months)
For the first loan:
r = 4% / 12 = 0.00333 (approximately)
n = 10 years * 12 = 120 months
PV = $50,000
Plugging these numbers into the formula, we get the monthly payment for the first loan.
For the second loan, we do the same calculation, but with r = 3% / 12 and n = 20 * 12.
After we have the monthly payments, we multiply each by the total number of payments (n) to get the total repayment amount for each loan. The loan with the lower total repayment amount is the one Connor should select.
I hope that helps
Answer:
Connor should select the 10-year loan because it has a lower total cost than the 20-year loan.
Step-by-step explanation: To calculate the total cost of each loan, first find the monthly payment of the loans. Use the formula below to find the monthly payments, where P is the monthly payment, L is the principal amount of the loan, i is the interest rate, and n is the duration of the loan.
P=L×i1−(1+i)−n
The loan amount needed, L, is $50,000 for both loans. Since the interest rate is compounded monthly, the interest rate offered is 4% per year or 0.0412 per month. The time period is 10 years or 120 months. Substituting the values into the formula and converting the interest rate to the monthly rate yields the following.
PP=50,000×0.04121−(1+0.0412)−120≈$506.23
Multiply the monthly payment by the number of months in the loan, 120, to determine the total cost of the loan.
$506.23×120=$60,747.60
Now calculate the monthly cost of the 20-year loan.
PP=50,000×0.03121−(1+0.0312)−240≈$277.30
$277.30×240=$66,552
Since the total cost of the 10-year loan, $60,747.60, is less than the total cost of the 20-year loan, $66,552, Connor should select the 10-year loan.
Your answer:
Connor should select the 20-year loan because it costs less than the 10-year loan.
The 20-year loan has a total cost of $66,552 while the 10-year loan has a total cost of $60,747.60.
1.5 hours
To find how long it took for them to travel 12km, subtract 8 from 12. (4)
If it took them 1 hour to travel 8km and 4 is half of 8, then it would have took them 1 and a half hours to travel the 12km.

B. –2 < x < 2
C. –6 < x < 2
D. –21 < x < 3
The solution to the inequality |3x + 6| < 12 is -6 < x < 2, which corresponds to option C.
To solve the inequality |3x + 6| < 12, we can break it down into two separate inequalities:
3x + 6 < 12
-(3x + 6) < 12
Solving the first inequality:
3x + 6 < 12
Subtracting 6 from both sides:
3x < 6
Dividing both sides by 3 (since 3 is positive, we don't need to change the direction of the inequality):
x < 2
Solving the second inequality:
-(3x + 6) < 12
Distributing the negative sign:
-3x - 6 < 12
Adding 6 to both sides:
-3x < 18
Dividing both sides by -3 (since -3 is negative, we need to change the direction of the inequality):
x > -6
Combining the solutions from both inequalities, we have:
-6 < x < 2
Therefore, the correct option is C. -6 < x < 2.
