Roberto is not familiar with tape diagrams and believes that he can show the relationship of multiplication and addition on a number line. roberto demonstrate that the expression 3 × 2 is equivalent to 2 + 2 + 2 on a number line.

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.
