June can paint a room in 5 hours. Kathryn can paint the same room in 3 hours. How long will it take them to paint the room together?

Determine the standard form of the equation of the line that passes through (-2,0) and (8,-5)

To factor 4x2-25, you can first rewrite the expression as:

Part a: explain why the x-coordinates of the points where the graphs of the equations y = 2−x and y = 8x+4 intersect are the solutions of the equation 2−x = 8x+4. (4 points) part b: make tables to find the solution to 2−x = 8x+4. take the integer values of x between −3 and 3. (4 points) part c: how can you solve the equation 2−x = 8x+4 graphically? (2 points)
