How can you represent an increase or decrease in temperature using an addition equation?

Can someone explain to me how to do

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.

Using graph paper, determine the line described by the given point and slope. click to show the correct graph below.(0, 0) and 2/3
