Describe another way to show that the angles in this quadrilateral add

Look at this expression. a3b3c a-3b-3c-1 which of the following is the simplest form of the expression above?

How many solutions does the nonlinear system of equations graphed below have?

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.
