Iam trying to solve a linear equation for the shoe size of someone 84" tall taking into consideration example 1 is 69" tall with a shoe size of 9 and example 2 is 72 inches tall with a shoe size of 11. i understand that the equation should be y=mx+b and that on the graph the answer is (3,2) but i just don't understand how to create the equation to solve for 84-inches and 60-inches tall questions. after two days, i need .

What value of x is in the solution set of 4x - 12 s 16 + 8x? -10 -9 -8 -7

Wich statement could be used to explain why the function h(x)= x^3 has an inverse relation that is also a function
