To solve a quadratic equation in the form $ax^2+bx+c=0$ you can use the quadratic formula:

$x_(1,2) = (-b\pm√(b^2-4ac))/(2a)$

In your case, the equation $x^2-4x+29=0$ is identified by the coefficient choice $a=1,\ b=-4,\ c=29$ , so the solving formula becomes

$x_(1,2) = (4\pm√(16-116))/(2) = (4\pm√(-100))/(2)$

As you can see, we have a negative number under a square root, an operation impossible to perform using real numbers. So, this equation has no real solutions.

A $1,500 loan has an annual interest rate of 4 1/4% on the amount borrowed. How much time has elapsed if the interest is now $127.50?

Answers

$ $127.50=1,500(0.0425)*x$

$ $127.50 = 63.75 *x$

$x = (127.50)/(63.75)$

$x = 2$

2 years elapsed.

hope this helps!

Answer:

2 years

Step-by-step explanation:

Given : A $1,500 loan has an annual interest rate of 4 1/4% on the amount borrowed.

To Find : How much time has elapsed if the interest is now $127.50?

Solution :

Formula of simple interest : principal *rate *time

Principal = $1,500

Rate (in decimals ) $4(1)/(4*100) =(17)/(4*100) =0.0425$

Time (in years)

Simple interest = $127.50

Putting values in formula

$127.50 = 1500*0.0425*time

127.50 = 63.75*time

$(127.50)/(63.75)$ = time

2 years = time

Thus time will be 2 years
