70x + 490=1050
-490 -490\
70x= 560
divide both sides by 70
x = 8
8 passengers
Neither. When graphing both lines they intersect but are not perpendicular.
4 < = x + 4 < = 8.....subtract 4 from all sections
4 - 4 < = x + 4 - 4 < = 8 - 4...simplify
0 < = x < = 4
this would produce a number line with a solid circle on 0 and a solid circle on 4, with shading in between....just like the graph shown in the picture u posted.
so the expression u would add would be : x + 4
12.195+9.13=21.325 is the answer
