What is (1.6x + 7.3) + (–0.6x + 2) – (7.8 – 3.4x), simplified?

(1.6x + 7.3) + (–0.6x + 2) – (7.8 – 3.4x)

1.6x + 7.3 – 0.6x + 2 – 7.8 + 3.4x

1.6x – 0.6x + 3.4x + 7.3 + 2 – 7.8

x + 1.5

Sample response: if the graph passes the horizontaline test, then the function is one to one. functions that are one to one have inverses that a therefore, the inverse is a hinction compare your response to the sample response above. what did you include in your explanation? a reference to the horizontal-line test d a statement that the function is one-to-one the conclusion that the inverse is a function done
