is x = 3 a solution to the equation 12x + 4 = 7x +19? Explain
Yes, when 3 is substituted for x, the left and right sides of the equation are equal.
A 12-foot ladder is leaned against the side of a building. If the bottom of the ladder rests 3 feet from the wall, determine the height at which the top of the ladder rests on the wall.
11.6ft
A line with the slope 3/7 passes through the point (4,2). Is the point (-130, -57) on this line? Explain.
No. The slope of the line through this points (-130, -57) and (4,2) is 59/134, not 3/7
