If you are wonder how many seat there are left there would be 44 seats unoccupied. 200-156=44
The Answer is -6+3=-3 because the little dot thing starts at -6 but it’s going to the right so when it goes to the right that means your going to have to add so your going to add 3 and if you add -6+3 you will get negative three ! Hope this helps !
Answer:
As polar ice caps melt, the coastal areas would face the most significant immediate threat because when the ice caps melts,the water level in the oceans and seas increases, which may harm the coastal regions by sudden tsunami or some other disaster related to water.

The y value would be -1.5 in order to get roots of -.5 and -1, one of which is double the other.
In order to find this, we can set the roots values at root#1 = a and root#2 = 2a. This is because we know the second should be twice the first one. Now, knowing the way that factoring works, we know that the two roots added together must equal the middle term, and multiplied together must equal the final term.
a + 2a = -y
a(2a) = y - 1
Now we can solve the first one for y and plug that into the second equation.
a + 2a = -y
3a = -y
-3a = y
Place into the next equation.
a(2a) = y - 1
a(2a) = -3a - 1
2a^2 = -3a - 1
2a^2 + 3a + 1 = 0
Now we can use this quadratic to find the roots. These roots would be -1 and -.5. We can now use this in parenthesis to find the standard form of the equation.
(x + 1)(x + .5)
x^2 + 1.5x + .5
Now that we have this, we can solve for the y using either the middle or end term. We'll use the middle term for the purpose here.
1.5x = -yx ----> divide by x
1.5 = -y ---> divide by -1
y = -1.5
