17) 2u - 6u = -4u
30) ((-7)+(-2)+5+ 10+12+18)/6 = 36/6 = 6

17) 2u-6u=-4u
30)-7+-2+5+10+12+18=36/6=6
46)x-2y>4=x>4
-2y>4
y=-2

2u-6u=-4u
-7-2+5+10+12+18=36/6=6
x-2y>4
x>4
-2y>4
y>-2

17) since the variables are the same, just subtract the coefficients, 2 from 6. -4u
30) add all the numbers together and divide by the amount present, so after you get the sum, divide the number by 6 to get the mean
46) put it in slope intercept form, y = mx + b, then graph both of them and shade in the areas that apply to the inequalities. do this by testing a point such as (0,0) to test which side of the graph is shaded. after shading, you will know what x and y can equal while still satisfying both inequalities.

17.) -4u
30.) mean = average
5+10=15
15/2=7.5
mean is 7.5
46.) and ...um no idea.. do u find y or someting?
