The average rate of change (ARC) of the function y = f(x) between xy and x2 is f(x2) - f(xi)
ARC =
X2-X
Use appropriate substitution(s) to show that the ARC formula comes from a familiar slope formula.

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
