Answer:
x+y=15
Step-by-step explanation:
Given equation of 
Differentiating both side 

It passes through the point (12,3) so

So equation of tangent passing through (12,3) is
as 
So x+y =15 will be the equation of tangent which passes though the point (12,3)

please mark brainliest
Multiples of 30 : 30,60,90,120,150....
and the first one that 4 goes into evenly is 60
You can either make a table using any numbers you would like (I would suggest -5 to 5) and then graphing the rule
ex. (7/2)(-5)-2 = -19.5 (I multiplied (7/2) by -5 and then subtracted 2)
Or you can put the rule in a graphing calculator and check the points from there
