What is the slope of a line that is perpendicular to the line whose equation is ax+by=c?
Oksi-84 [34.3K]

The perpendicular line will have a slope of b/a.

To find this, we first have to solve our equation for slope intercept form.

ax + by = c ----> subtract ax

by = -ax + c ----> divide by b

y = -a/bx + c/b.

So we know the slope of this equation to be -a/b. Since perpendicular lines have opposite and reciprocal slopes, we know we can simply flip the fraction and make it a negative to get the new slope of b/a.

42. Nathan bought a new computer for $875. He
Aleksandr-060686 [28]

Answer:

5%

Step-by-step explanation:

The equation for simple interest rate is as follows:

A = P(1+rt)

A = final amount

P = initial principal amount

r = annual interest rate

t = time (in years)

So, we need to plug everything in and solve for r:

The final amount is equal to $875 plus the interest of $131.50.

A = 875 + 131.50 = 1006.50

Now, plug everything in:

1006.50 = 875( 1 + r(3))

Solve:

1 + 3r = 1.15028571                            Divide 1006.50 by 875

3r = 0.15028571                                Subtract 1 from 1.15028571

r = 0.050                                           Divide by 3

The simple interest rate would be 5%. I converted the r to a percent by multiplying 0.050 by 100.

I hope this helps!! Ask questions if you need!!
