Write an inequality for each description. one fourth of the opposite of the difference of five and number is less than twenty.

1/4(-5+n) < 20 the opposite of 5-n is -5+n

multiply by 4

-5 + n < 80

+ 5

n< 85

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
