If fx)= 4x+9+2, which inequality can be used to find the domain of f(x)?

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

b

step-by-step explanation:

the answer to this in exact form is 4/35 but in decimal form its 0.1142857

hope this if needed hmu
