X = number of cds on the rack
x + 7 = 30
x = 30 - 7
x = 23 <== so there are currently 23 cds on the rack
The graph represents a function but the table does not. The reason for this is that one input value (70) in the table is associated with two output values (54.6 and 53.11), which is a sure sign that we do NOT have a function here.
Minus 6 both sides
4>x/3
times3 both sides
12>x
Point m is the midpoint of AB. if the coordinates of m (2,8) in the coordinates of A (10, 12) are the coordinates of B this is your answer 4/8
