21 glass spheres each of radius 2cm are packed

i can answer this question sweetie!

step-by-step explanation:

the correct is answer is a 9-sided polygon!

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.

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)
