(b) 2
(c) 3
(d) -6

Answer 1

Answer:

3

Step-by-step explanation:

For a point to lie on the x axis, it's y coordinate must be equal to 0.

Every point on x axis of coordinate axis is of the form (x, 0) where x is its distance from the origin. This distance will be -ve on left side of axis whereas positive on right side.

Since in the question, we have to find the value of a for which the point C( 3, a-3) lies on the x axis, it's y coordinate must be 0.

Therefore,

=> a - 3 = 0

=> a = 3

Hence 3 is the correct answer.

Answer 2

Answer:

a is 3 please mark brainliest
