1 = 25
I only know that problem that is it.
Answer:
Domain:
(−∞,∞), {x|x ∈ R}
Step-by-step explanation:
CF = CD + DF (since D is simply a point on the line, and C to that point added onto F to that point is CF), so 4y-9+2y-7=14. Adding it up, we get 6y-16=14 and adding by 16 we get 30=6y. Dividing both sides by 6, we get y=5. Plugging that into DF, we get 10-7=DF=3
