The average distance from the Earth to the moon is 238,855 miles. If the speed of light is 186,282 miles per second, can you set up an equation representing the time in seconds it takes light to travel from the moon to the Earth? How long does it take? Are you seeing into the past when you look at the moon?​

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.
