2x + 3y = 9 -2x + 2y = 6 the y-coordinate of the solution to the system shown is a. 3 b. 5 c. 9 d. 15

Which expression is equivalent to (3^2)^-2 a.-81 b.-12 c.1/81 d.1/12

Whats the name of the vertical axis

Consider this equation. |y + 6| = 2 what can be concluded of the equation? check all that apply. there will be one solution. there will be two solutions. the solution to –(y + 6) = 2 will be also be a solution to the given absolute value equation. the solution(s) will be the number(s) on the number line 2 units away from –6. the value of y must be positive since the variable is inside absolute value signs.
