Which equation represents a nonlinear function?

Answer and the Step-by-step explanation : -

1) x(y - 5) = 2

First you gotta open the brackets so then you'll get : -

xy - 5x = 2

Answer : - " since xy is remaining the equation will not linear "

2) y - 2(x + 9) = 0

"y - 2x - 18 = 0 "

"Y = 2x + 18 "

Answer : - "This is linear"

3) 3y + 6(2 - x) = 5

3y + 12 - 6x = 5

3y = 5 - 12 + 6x

3y = 6x - 7

Y = 2x - 7/3

Answer : -This is linear

4) 2(y + x) = 0

2y + 2x = 0

2y = - 2x

y = - x

Answer : - " This is linear "

1) x(y - 5) = 2

Step-by-step explanation:

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

both equations and proportions are better.
