only group 1 n 3 are explained - u attached 3 twice n missed 2

Step-by-step explanation:

group 1:

all of 'em have no sol'n

each graph in a set of eqns are parallel to the other

each set of eqns has the same slope

4 a set of eqns, if they have the slope, they are parallel lines with no sol'n.

group 3:

all of 'em have infinite no. of sol'ns

each graph in a set of eqns overlap with the other

each set of eqns are identical but with a different multiplier

4 a set of eqns, if they are identical, their graphs will overlap with infinite no. of sol'ns.

answer: h=5.6 i don't really know how to put into words, so i though i would let you do that. i hope i was able to some

step-by-step explanation:

18 = 6(h)+1/2

18 = 6h+1/2

18-1 = 6h/2

17 = 3h

17/3 = h

h = 5.6
