a company borrowed 25,000 and was charges 3.5% and was charged 2,625 in interet...how long was it before the company repaid the

Sladkaya [172]

We'll have to assume that interest is charged annually.

interest = i = p*r*t, where p is the initial amount ($25000), r is the annual interest rate as a decimal fraction, and t is the length of time, in years.

Then $2625 = $25000*0.035*t. Solve for t:

$2625
------------ = 0.035t = 0.105. Dividing both sides by 0.035, we get
$25000

t = 3 years (answer)

Find an equation perpendicular to x=1 and passing through (8,-9)

valina [46]

Answer:

$y=-9$

Step-by-step explanation:

We want to find an equation of a line that's perpendicular to x=1 that also passes through the point (8,-9).

Note that x=1 is a vertical line since x is 1 no matter what y is.

This means that if our new line is perpendicular to the old, then it must be a horizontal line.

So, since we have a horizontal line, then our equation must be our y-value of our point.

Our y-coordinate of our point (8,-9) is -9.

Therefore, our equation is:

$y=-9$

And this is in standard form.

And we're done!
