1.) list some repeating decimal fractions .2.) the square root of , like 4,9 or 16 is a (n) number .3.) when a decimal goes forever without repeating, it is a (n) number.

1) Repeating decimal fractions: 0.123123123 ... , 0.0729729729 ...

2) The square root of a perfect square, such as 4, 9, 16, etc., is a rational number.

3) When a decimal goes on forever without repeating it's an irrational number.

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

step-by-step explanation:

so, converting firstly the mixed fractions to improper fractions and then "adding".
