📝 Answered - Solve the equation for the given variable. Do NOT convert the answer to a decimal. [tex]$\frac{y}{5}+\frac{y}{6}=\frac{3}{5}$[/tex]

📝 Answered - Suppose the graph of f(x) = √x is shifted down 4 units and to the left 5 units. What is the equation of the new graph? Verify the result graphically. The equation of the new graph is g(x) = (Simplify your answer.)

📝 Answered - Verify that the equation is an identity. $\frac{\cos \theta+1}{\tan ^2 \theta}=\frac{\cos \theta}{\sec \theta-1}$ To verify the identity, start with the more complicated side and transform it at each step. $\begin{array}{l} \frac{\cos \theta+1}{\tan ^2 \theta} \ =\frac{\cos \theta+1}{\sec ^2 \theta-1} \ =\frac{\cos \theta+1}{\square} $\end{array} $\tan ^2 \theta+1=\sec ^2 \theta$ $\square$
