Answer:
- Interests charged for 4 years: $80
- Total amount to pay back:$480
Step-by-step explanation:
- To know the future value of an specific amount that is borrowed from a bank we use the following equation:
, where FV is future value, PV present value, n the amount of periods and i the interest rate. - In this particular case, the present value of the loan is $400, n=4 (4 years), i=5%. Then the future value equals:
. Then FV= $480, which is the total amount of money she would have to return in 4 years. - The interest paid can be calculated as the total amount paid ($480) minus the inicial loan ($400), which means that total interests paid= FV- PV= $80.
Answer:
3y+4
Step-by-step explanation:
this is combining like terms meaning the two "y" numbers combine together
9y-6y
then you just keep the 4 since it cannot be combined with anything else here since it has no variable
Answer: I think A
Step-by-step explanation:
Answer:
12
Step-by-step explanation:
To find the best predicted value of y, substitute 5 for x in y = 5x + 2.
We get y = 5(5) + 2, or 12.
Answer:
38 degrees
Step-by-step explanation:
this is an isosceles triangle, meaning that the base angles are congruent.
the total triangle is equal to 180
so the equation would be: x=180 - (71+71)
evaluate:
x=180-142
x=38 degrees
Hope this helps :)
