Model with Mathematics Write about a real-world situation that can be represented by the equation y = 7x. Be sure to explain what the variables represent in the situation.
Persevere with Problems The inverse of a relationship can be found by switching the coordinates in each ordered pair. Complete the table for three input and output values of y = x + 3 and its inverse. Then use the table to write an equation of the inverse of y = x + 3.
