3years ago clear borrowed money from her father to pay for a class trip she agreed to pay 6% simple annual interest on the loan now she owes him $90 an interest plus the principal amount how much did claire

The principal amount was $500.

Step-by-step explanation:

Simple (non-compound) interest $90 for three years means $30 for 1 year.

Knowing the interest amount for one year and the interest rate 0.06 (6%) we can determine the principal from:

(interest) = (principal) x (interest rate)

$30 = (principal) x 0.06

=> (principal) = $30 / 0.06 = $500

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
