Answer:

$5518.93

Step-by-step explanation:

Compound interest formula:

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

where P is the principal (starting amount), r is the interest rate, n is the number of times compounded per year, and t is the time in years.

The known variables are:

P = $4700
r = 5.5%
n = 1
t = 3

Plug those 4 into the equation now and solve for A:

$\rightarrow A=4700(1+0.055)^3\\\rightarrow A=4700(1.055)^3\\\rightarrow A=4700\times1.1742\\\rightarrow A=5518.9345$

Y-x=15 y-x=5 using elimination

Galina-37 [17]

Answer:

No solution

Step-by-step explanation:

To eliminate is to get rid of one of the variables.

You can choose to either add each term in the equations or subtract each term in the equation.

For a variable to be eliminated, there must one pair that have the same constant with it. Each equation already has the same constant with a variable.

Try adding them.

. y - x = 15

2y - 2x = 20 No variables were eliminated.

Try subtracting.

. y - x = 15

0y - 0x = 10 All variables were eliminated.

. 0 = 10 This is false.

This system of equations cannot be solved.

Graphically, these two lines would have the same slope and are parallel. The solution to a system is same as the point of intersection. Parallel lines never meet, never intersect, therefore there is no solution.
