Answer:

The provided equation has infinite solutions.

Step-by-step explanation:

Consider the provided equation.

-4x-7+10x=-7+6x

The above equation can be written as:

-4x+10x-7=-7+6x

Add the like terms.

6x-7=-7+6x

This can be written as:

6x-7=6x-7

Here, we can see that left side is same as the right side.

For any value x the left and right side will be same.

Check:

Substitute x=1

6(1)-7=6(1)-7

6-7=6-7

-1=-1

Substitute x=2

6(2)-7=6(2)-7

12-7=12-7

5=5

Hence, the provided equation has infinite solutions.

Suppose payments were made at the end of each month into an ordinary annuity earning interest at the rate of 4.5%/year compounde
valentina_108 [34]

Answer:

each payment = $214.20

Step-by-step explanation:

For ordinary annuity,

FVOA = PMT x [{(1+r/m)^(n*m)} - 1/(r/m)]

Here, FVOA = $50,000

year, n = 14

Since the interest will be paid monthly, m = 12

interest rate, r = 4.5% = 0.045

PMT = ?

Putting all the values into the ordinary annuity formula,

FVOA = PMT x [{(1+r/m)^(n*m)} - 1/(r/m)]

$50,000 = PMT x [{(1+0.045/12) ^ (14*12)} - 1/(0.045/12)]

or, $50,000 = PMT x [{(1+0.045/12) ^ (14*12)} - 1/(0.045/12)]

or, $50,000 = PMT x [(1.8754 - 1)/0.00375]

or, $50,000 = PMT x [(1.8754 - 1)/0.00375]

or, $50,000 = PMT x 233.4399

or, PMT = $50,000/233.4399

PMT = $214.19

or, monthly payment will be $214.20 (Nearest cent)
