Determine whether each statement is true or false. If the statement is false, make the necessary change(s) to produce a true statement. Divide and express the result in standard form: $$\frac{4 i+7}{5-2 i}$$
Complete the square and write the equation in standard form. Then give the center and radius of each circle and graph the equation. $$x^{2}-2 x+y^{2}-15=0$$
