What is the index of equation and what does it mean to you in terms of simplifying this expression?

The goal in simplifying numbers is to reduce it that can be best seen in the eye. In here, you are given 5a x 2c x 3d. Note that 5, 2 and 3 are coefficients and a, c and d, are variables. Multiply first the coefficients 5, 2 and 3 and you get 30. Always remember that in multiplying numbers, especially variables, the base of the exponent must be equal. However, you have variables of a, c and, d. You cannot multiply or add them because they are different. So the answer is 30acd.

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.
