Simplify. write your answers in scientific notation.

Divide 243 by 3:

243 / 3 = 81

Subtract the exponents:

8-2 = 6

So you have 81 x 10^6

Now move the decimal point on 81 to have one digit to the left of the decimal point and then add the number of moves to the exponent.

81 becomes 8.1, and you moved the decimal 1 place, so add 1 to the ^6:

Answer is 8.1 x 10^7

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.
