This one is probably f(x)=2(4)
Answer:
CB= 4
Step-by-step explanation:
the triangles are in AA similarity.
AB/AD = BC/DE
4/12 = x/12
CROSS MULTIPLY;
x = 48/12
x = 4
Answer:
(3,6)
Step-by-step explanation:
-2x+3y=12
Let x = 3
-2(3) +3y = 12
-6+3y = 12
Add 6 to each side
-6+6 +3y = 12+6
3y = 18
Divide each side by 3
3y/3 = 18/3
y = 6
