Answer:

This question is impossible! For two different variables, we need two different equations. Without that, there is no hope! :)

Answer:

c= -z-2

Step-by-step explanation:

7-5c=17+5z\\\\\mathrm{Subtract\:}7\mathrm{\:from\:both\:sides}\\\\7-5c-7=17+5z-7\\\\Simplify\\\\-5c=5z+10\\\\\mathrm{Divide\:both\:sides\:by\:}-5\\\\\frac{-5c}{-5}=\frac{5z}{-5}+\frac{10}{-5}\\\\Simplify\\\\c=-z-2

Enter the number of complex zeros for the polynomial function in the box.
NikAS [45]
Since the equation has a degree of 5 then, it will definitely have 5 zeroes. Complex zeroes of the polynomial always come in pair such that even if there are five zeroes, the complex zeroes could only be either 2 or 4 or none. 

Hence, the answer to this item is none, 2 or 4.
