Every triangle must have an acute angle. True or false?

Solve for x, y, and z. show all steps.

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2

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
