Can anyone solve this question ?? I have to find the value of unknown sizes​

Step-by-step explanation:

50 plus 50 is 100 we know that the number  left that is 80 that is so a 40 and x 40 as well

29 mil

step-by-step explanation:

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.
