At the college bookstore, used books sell for 35% less than new books. If Johanna's new science book cost $65, how much would the same book cost if it were used?

How many real and imaginary solutions does the equation x^2-3x=-2x-7 have?

Extra points! find the missing dimension! need asap

(05.03 mc) part a: explain why the x-coordinates of the points where the graphs of the equations y = 4x and y = 2x−2 intersect are the solutions of the equation 4x = 2x−2. (4 points) part b: make tables to find the solution to 4x = 2x−2. take the integer values of x between −3 and 3. (4 points) part c: how can you solve the equation 4x = 2x−2 graphically? (2 points)
