Step-by-step explanation:
Write the equations in the form y = mx + b
If the equation contains exponents then it is non-linear, if not then it is linear.
2xy = 3
This graph forms a curve so it is non-linear
y = 1x³ + 5
This equation is non-linear because it contains an exponent
y = x/3
y = 1/3x + 0
This equation is linear ( no exponent(s) )
2y = 1/2x
y = 1/4x + 0
This equation is linear ( no exponent(s) )

Step-by-step explanation:
If your cake looks done outside but remains uncooked/gooey in the center, it means that its not completely cooked. Always insert a skewer in the center of the cake towards the finishing time to see if it comes out clean. If it doesn't then cook for few minutes more, and check after 5-10 minutes.
