Answer 1

A and D is the correct answers.

Answer 2

Answer:

Option A - $2x + 3y=10$

Step-by-step explanation:

To find : Which equations represent functions?

Solution :

Function is defined as the relationship between two variables in which one variable is dependent s.t. for one variable we have the value of other.

From the given options,

A. $2x + 3y=10$

This is a function of variable x and y forming a linear equation.

B. $4x=16$

This is not a function as there is only one variable x.

C. $2x-3=14$

This is not a function as there is only one variable x.

D. $3y=18$

This is not a function as there is only one variable y.

E. $14.6+2x$

This is not a function as there is only one variable x.

Therefore, Option A is correct.
