Two central angles are listed below. column a 1.38 radians column b 77 degrees. compare the central angle in column a to that in column b. a. column a is larger than column b. b. column b is larger than column a. c. column a is equal to column b. d. the two columns cannot be compared because the units are different.

The statement that best compares the  central angle in column A to that in column B is:

    A.   Column A is larger than column B.

We are given the central angle of Column A as:  1.38 radians

and the central angle of Column B as: 77 degree

As the two units are different so will change them to the same units

We know the conversion:

   π radians=180°

⇒  1 radians=180°/π

⇒  1.38 radians= 79.06818°

Hence, the central angle of Column A is:  79.06818°

Since, 77° < 79.06818°

This means that the central angle of column A is larger than the central angle of Column B.

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
