(a) A photography student borrows RM2 500 to buy a camera. The bank loans this money at a rate of 9 % capitalized monthly. What
Monica [59]

Answer:

The student will have to reimburse 2,991.03 two years later.

Step-by-step explanation:

This is a compound interest problem:

The compound interest formula is given by:

A = P(1 + \frac{r}{n})^{nt}

In which A is the amount of money, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit t and t is the time the money is invested or borrowed for.

In this problem, we have that:

A is the amount the student will have to reimburse two years later.

P is his loan. so P = 2,500

The bank loans this money at a rate of 9 % capitalized monthly. This means that r = 0.09 and n = 12, since the money is compounded monthly, this means, 12 times in a year.

He will have to reimburse two years later, so t = 2

A = P(1 + \frac{r}{n})^{nt}

A = 2,500(1 + \frac{0.09}{12})^{24}

A = 2,991.03

The student will have to reimburse 2,991.03 two years later.

Solve the system. 4x−y=−3y=5x
alina1380 [7]

Answer:

4x - y = -3y = 5x

Write as a system

4x-y = 5x

-3y = 5x

Simplify the expressions

-x-y = 0

-5x-3y = 0

Multiply both sided by -5

5x + 5y = 0

-5x - 3y = 0

2y = 0

y = 0

Substitute the value of y into the equation

-x-0= 0

x=0

A possible solution is (x,y) = (0,0)

Which ordered pair is a solution of this equation?X-5y=-31
mihalych1998 [28]
D. When you substitute for the variables the equation becomes -1-5×6=-31. First, you multiply -5 by 6 to get -30. This makes the equation -1-30=-31. -1-30 is -31 so your equation is now -31=-31.
