Final answer:
Federal and state agencies share responsibilities such as collecting taxes, building highways, and enforcing laws. Intergovernmental revenues are shared to fund specific areas like welfare and education.
Step-by-step explanation:
The responsibilities shared by federal and state agencies include collecting income and corporate taxes, building and maintaining the network of interstates and highways, and making and enforcing laws. For example, state governments have laws regulating motorcycle and bicycle helmet use, banning texting and driving, and prohibiting driving under the influence of drugs or alcohol. Additionally, the federal government shares some of its revenues with the states and local governments through intergovernmental revenues, which are used to fund specific areas such as welfare, healthcare, and education.
