Simplify the expression with the given variable’s ?! 3r-4s, when r= 5 and s= 2/3

12.33

Step-by-step explanation:

3r-4s

3×5-4×2/3

15-8/3

12.333

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.
