0.5 (20x - 50 y + 36) -0.25 (-100 x + 40 y - 12 is simplified what is the resulting expression

What is the average rate of change for this function for the interval from x=2 to x=4 ?

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.
