Plz ! timed ! graph the equation and describe any line symmetry. y=( x+10)² select one: a. it does not have line symmetry. b. it has line symmetry across the y-axis. c. it has line symmetry across the line x = -10. d. it has line symmetry across the x-axis.

Part of the total score for each program is the sum of five program component scores. on the free program, the sum of these five program component scores is multiplied by a factor of 2.0. yuzuru hanyu, of japan, earned scores of 9.07, 8.96, 8.89, 9.21, and 9.36 for the program components portion of his free program. how many total points did he receive for this portion?

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2

Solve for n? [tex]z = \frac{3}{4} mn[/tex]
