Me out with this math question
f de is a mid segment of the triangle, then the measure of ac:

7.5
15.
30.
none of the choices are correct.

X+ y = 5 ; x - y =3 solve using linear combination

Identify the initial amount a and the growth factor b in the exponential function. a(x)=680*4.3^x

Describe the end behavior of the function below. f(x)=(2/3)^x-2 a. as x increases, f(x) approaches infinity. b. as x decreases, f(x) approaches 2. c. as x increases, f(x) approaches -2. d. as x decreases, f(x) approaches negative infinity.
