What is the formula for simple interest? A= (P + 1) rt

I = Prt

I = SiL

A = P (r + 1) t

Itook a better photo of the question so y’all can see it i hope it’s a fine photo

Karianne and lucius are analyzing a linear function on a graph. karianne says that unit rate is equal to rate of change, but that slope is calculated differently. lucius says that unit rate, rate of change, and slope are calculated the same way. who is correct? explain your answer.

Simplify this expression.2(10) + 2(x – 4) a. 2x + 16 b. x + 12 c. 2x + 12 d. x + 16
