Simplify:

4x+2-x+12+3x

a
3x-14
b
6x+14
c
3x+14
d
6x-14

6x +14

Step-by-step explanation:

4x+2-x+12+3x

Combine like terms

4x -x +3x   +2 +12

6x               + 14

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4

a.for lorena 14 hours makes $126   for 16 hours she makes 144

for julie 6 hours makes $72 for 21 hours its $252
