select all of the correct answers for the values of x in each of the angles D, E and C in the following regular heptagon: <D=(5x+5Y=(7x+1)°, <X=(7/2x+2)°

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

answer:

your answer is: c. 196 7/8 in^3.
