Identify the range of the following numbers:
100, 212, 215, 308, 303,600.

500

Step-by-step explanation:

To find range, you subtract the lowest value from the greatest value.

First you have to put the vaulues in order from least to greatest

100, 212, 215, 303, 308, 600

then,

600-100=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
