6. domain=age
range= number of pets
it is not a function because an x value repeats
7. domain=1,2,3,4,5
range= 50, 100, 150, 150, 200
it is a function because the lines don't connect
I believe the answer would be D, 2y+6/9y-7 x 3/2 because dividing by a fraction is the same as multiplying by its reciprocal (the fraction flipped).
Hope I helped! ;)
1: 2.5 2:0.4 3:12.5 4:0.08 hope this helps
For example
2 pencils cost one dollar
Then one pencil costs 50 cents. We just found out the cost per unit of the pencil.
Hope that helped :)
