It is the last one (x+3)2
Step-by-step explanation:
(3x+6)= 48(Alternate angles)
3x=48-6
3x=42
x=14
2y+48=5y-9 (Sum of two opposite interior angles= exterior angle)
48+9=5y-2y
57=3y
y=19
For this case you have the following advantages:
1) you can see the graph of both equations
2) you can see where the equations intersect
3) the point of intersection represents the solution to the system of equations.
4) You can solve the problem in much less time than doing it by hand
5) You can find very accurate solutions.
It is 1/5 because it is 1 difference on the top and a 5 difference on the bottom number
