if m∠3=(4x+12)° and m∠7=(80-x)° where x=15 would lines M and L be parallel? If the lines are NOT parallel, then what value of x would make them parallel?

Consider the following equation. 1/2x^3+x-7=-3sqrtx-1 approximate the solution to the equation using three iterations of successive approximation. use the graph below as a starting point. a. b. c. d.
