en un determinante de una matriz de 2x2, si las filas son iguales ¿cuál es el valor de la determinante?

Does anyone know how to solve and graph this: 4 + | a + 2 | < 7the only part i don't get is the "4 +"

In order for the function to be linear, what must m be and why? m = 22 because the rate of change is 1. m = 20 because the rate of change is 3. m = 22 because the rate of change is -1. m = 20 because the rate of change is -3.

Have yall ever just farted and was like, i farted.
