Narrative:

On vector to visual approach runway xx; ZZZ; approach provided traffic outbound to south at 3;500 feet. Approach and tower were combined and appear to underestimate our closure rate on the vector to join final as visual backed by ILS runway xx. Other traffic (aircraft Y) was monitored through all stages by pm TCAS display which was active the entire flight. Pm and PF visually sighted traffic and paused descent whilst turning inbound for final. After this action first TA then RA triggered with monitor vs and arc guidance to maintain alt; which was action already active. Normal approach and landing once visually clear of traffic.cause - poor vector and then visual approach clearance whilst traffic outbound in approach display and conflicting altitude.more ATC resources; combined approach and tower may have been a factor.
