What is the value of z so that –9 and 9 are both solutions of x² + z = 103? (1 point) Responses –22 –22 3 3 22 22 184
To find the value of z, we can substitute the given values of x into the equation x² + z = 103.
For x = -9:
(-9)² + z = 103
81 + z = 103
z = 103 - 81
z = 22
For x = 9:
(9)² + z = 103
81 + z = 103
z = 103 - 81
z = 22
Thus, the value of z is 22.
