18 tangent to the curve y find equations of all lines having slope 2 that are x-8 select the correct choice below and fill in the answer box(es) within your choice. o a. there are two lines tangent to the curve with a slope of 2. the equation of the line with the larger y-intercept is (type equations.) and the equation of the line with the smaller y-intercept is b. there is only one line tangent to the curve with a slope of - 2 and its equation is (type an equation.)

Asays "we are both knaves" and b says nothing. exercises 24–31 relate to inhabitants of an island on which there are three kinds of people: knights who always tell the truth, knaves who always lie, and spies (called normals by smullyan [sm78]) who can either lie or tell the truth. you encounter three people, a, b, and c. you know one of these people is a knight, one is a knave, and one is a spy. each of the three people knows the type of person each of other two is. for each of these situations, if possible, determine whether there is a unique solution and determine who the knave, knight, and spy are. when there is no unique solution, list all possible solutions or state that there are no solutions. 24. a says "c is the knave," b says, "a is the knight," and c says "i am the spy."

The train station clock runs too fast and gains 5 minutes every 10 days. how many minutes and seconds will it have gained at the end of 9 days?
