3 is one of the functions
Vertical angles are always equal.
To find the value of y, compare the angles.
4y=2y+5
Subtract 2y from both sides
2y=5
Divide both sides by 2.
y=5/2
Option D is correct.
X= 9.0 -y
=> 0.5(9-Y) +0.2Y=4.05
=> 4.5-0.5Y+0.2Y=4.05
=> 0.45=0.3Y
=> Y= 1.5, X=7.5
X is any number between -1 and 6.
Numbers x can be:
x=-1
x=0
x=1
x=2
x=3
x=4
x=5
x=6
