How did the aztec connect the Capital to the rest of the empire? plz help and fast

One of the ways in which the Aztec expanded in strength and wealth at the time was by acting as mercenaries and warriors for other societies in the region. For example, in the decades after the founding of Tenochtitlan they worked as warriors for the Tepanec people. The Tepanec used the Aztec to help with their battles and campaigns in the region against other rival societies. For their help the Aztec received portions of the wealth that the Tepanec gathered from the societies that they defeated. As a result, the city of Tenochtitlan grew in importance and wealth throughout the 14th and 15th centuries. In general though, the Aztec were subjects of the more powerful Tepanec and Aztec leaders were only allowed to remain in power by paying tribute to the Tepanec. Also, during this time period, Aztec rulers increased the power of their society by forming strong alliances with other societies around Lake Texcoco. However, the relationship between the Aztecs and the Tepanec soon became strained and a conflict emerged.
