Answer:
Step-by-step explanation:
Alright, lets get started.
The original photo size is 4 inches wide and 6 inches tall.
So, the ratio of width and height will be = 
The new enlarged photo will be of the same ratio means 2:3
The width of enlarged photo is given as 12 inches.
Suppose new height of enlarged photo is H, so

Cross multiplying

Dividing 2 in both sides
inches
So the height of new enlagred photo will be 18 inches. : Answer
Hope it will help :)
y=5/3x
this is because f(x)=x is one of (identity function) the 12 basic functions and when you multiply it it will shift it on the y axis
If you were to do y=x+5/3 it would make a horizontal shift to the left 5/3
So the unit your on is mostly about knowing the number located in the function that will make the graph shift different ways
the answer of the question is tens
(8+15+8+3+12)/2+1=24th number will be median
So median is gonna be 21
