(2/3)m tm= a + r, for m

m = √ 6 t ( a + r )/ 2 t   m = − √ 6 t ( a + r )/ 2 t

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

the equivalent expression are always the hardest ones but you look at the gcf also

step-by-step explanation:

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
