What number might be a good representation for the sea level

zero ( 0)

Step-by-step explanation:

The number that best represents sea level has always been 0. This is because sea level is meant to represent where the initial point where dry land meets the sea all around the world. Seeing since 0 is the universal neutral number which is neither positive or negative, it acts as the perfect number for sea level. Any elevation above sea level is in the positives while elevations under sea level would be in the negatives since it is lower than sea level and lower than 0 is negatives.

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
