A circle has a diameter of 9 inches. What is its radius?

Answer

12

Step-by-step explanation:

its because if u mulitply by 9 then divide by 3 then add 2 then subtract 20 then add 22 then add 7 u get 12

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.

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925
