If \( x \) is multiplied by 5 and then 3 is subtracted, then the function is \( f(x)=5 x-3 \). What are the steps to find the inverse to this function? a.) Multiply by 3 , then subtract 5 b.) Subtract by 5 , then multiply by 3 c.) Add 3 , then divide by 5 d.) Divide by 5 , then add 3

Simplify the following Expression \( \frac{7+3 i}{5+7 i}= \) Enter the answer as reduced fraction, when necessary. Examples. \( \frac{1}{2}-\frac{3}{4} i, 1-\frac{2}{3} i, 1+4 i \) If the answer is radical use sqrt(5) to denote \( \sqrt{5} \) (use the correct radicand in the problem!) If the answer is complex use i to denote \( i \). \( > \) Next Question
