Answer 1

Step-by-step explanation:

Case study:

Rekha was playing with his brother while she saw a brown layer on the iron grill of the window. She was trying to remove it but could not do that. Why?

Answer 2

Answer: a=-3/5

Step-by-step explanation:

Given: point $(4,5)$ lies on the line$3x-ay=15$

To find: the value of a?

Solution: It is given that point (4,5) lies on the given line that is 3x-ay=15

If the given point lies on the above line then the given point when put in the equation given, must satisfy the equation

Now as per the statement above put the point given that is $(4,5)$ in the given equation that is $3x-ay=15$

On putting the value of given point in the given equation it goes like this,

$3(4)-a(5)=15$

on further solving we get our equation as,

$12-5a=15$

on further solving we get our equation as,

$-3=5a$

now solve for the value of a and we get our value os a as,

Hence $a=-3/5$
