I need some help, I have this assignment due tomorrow.

If the two values have the same sign, then add and use the same sign.

If the signs are different, then subtract and take the sign of the number with the greatest absolute value.

Step-by-step explanation:

The first one is Add, the second one is different, and the thrid one is subtract

Step-by-step explanation:

1,645,493,059.35

step-by-step explanation:

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.
