Select the undefined term that best defines the arrow pictured

A line is the undefined term which best defines the arrow pictured

Step-by-step explanation:

There are three undefined terms in geometry are as follows

1) point  → has no dimensions

2) line  → has one dimension

3) plane. → has two dimensions

In the given picture, a line is the only undefined term which best fits to define the arrow pictured since arrow has only length, thus it has one dimension as a line.

5/12, or 5: 12

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
