The perimeter of a square can be represented by the
expression 8x – 10 + 8x - 10. Write an expression to
represent the length of one side of the square.

Step-by-step explanation:

perimeter of a square = 4 x length (L)

8x - 10 + 8x - 10 = 4L

rearrange the expression

8x + 8x - 10 - 10 = 4L

16x - 20 = 4L

divide both sides for L to stand alone

(16x - 20)/ 4 = 4L/4

(16x - 20)/4 = L

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.

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1
