Abuilding is 2 ft from a 12 ft fence that surrounds the property. a worker wants to wash a window in the building 17 ft from the ground. he plans to place a ladder over the fence so it rests against the building. he decides he should place the ladder 8 ft from the fence for stability. to the nearest tenth of a foot, how long of a ladder will he need?

Look at this system of equations. -3x + 3y = 12 y = x + 4 the solution set of this system is best explained by which of these statements? a) the graphs of the equations are the same line because the equations have the same slope and the same y-intercept. the system has infinitely many solutions. b) the graphs of the equations are parallel lines because they have the same slope but different y-intercepts. the system has no solution. c) the graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. the system has exactly one solution. d) the graphs of the equations are lines that intersect at one point because the equations have the same slope and the same y-intercept. the system has exactly one solution.
