Answer:

A = $56025

Step-by-step explanation:

Given that,

An investor decides to offer a business owner a $45,000 loan at simple interest of 3.5%  per year.

Principal, P = 45,000

Rate of interest, R = 3.5%

We need to find the total amount the investor will receive when the loan is  repaid after 7 years.

The formula for the simple is given by :

I=\dfrac{PRT}{100}\\\\=\dfrac{45000\times 3.5\times 7}{100}\\\\=\$ 11025

We know that,

Amount = Principal + simple interest

So,

A = 45,000 + 11025

A = $56025

So, the required amount is equal to $56025.

Consider the accompanying matrix as the augmented matrix of a linear system. State in words the next two elementary row operatio
Lubov Fominskaja [6]

Answer:

The answer is below

Step-by-step explanation:

The next step to solve the system, would be to divide the second row by 3 and we would be left with:  3 * R2

[1 -5 3 0 -2

0 1 -7/3 0 4/3

0 0 1 2 -2]

Then what we will do is multiply row 3 by 7/3 and then subtract it from row 2, that is, R2 - 7/3 * R3, and it would look like this:

[1 -5 3 0 -2

0 1 0 14/3 -10/3

0 0 1 2 -2]

And these would be the next two steps in the process of solving the system.

How many solutions are there to the system of equations? StartLayout enlarged left-brace 1st row 4 x minus 5 y = 5 2nd row negat
kkurt [141]

Answer:

Only one solution  x=\frac{5}{4},y=0

Step-by-step explanation:

4x-5y=5..............(1)\\0.08x+0.10y=0.10...........(2)

Multiply equation (2) by 50

4x-5y=5........(3)

Now from equation (1)+ equation(3)

8x=10\\x=\frac{10}{8}\\x=\frac{5}{4}

Put the value in equation (1)

5-5y=5\\5y=0\\y=0

hence only one solution exists\left(\frac{5}{4},0\right).
