Hi again, can you please help me on this, Write the fraction in simplest form.

Which equations represents circles that have a diameter of 12 units and a center that lies on the y-axis? check all that apply

Which of the following is true about the graph of f(x)=7^x. select all that apply. a= it intercepts the x axis b=it intercepts both axis c=it intercepts neither d=it intercepts the y axis

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2
