The answer is 11/10 or 1.1.
We can rearrange
x + y = 9
in to
y = 9 - x
This means the value of y is EQUAL to 9 minus the value of x.
[A] fits this description, because y (9) is equal to 9 minus x (0).
[B] does too, because y (0) is equal to 9 minus x (9).

</span><span>5t^2+20t+50 = 5 (t^2 + 4t + 10)</span>
Square root of 89 because 8^2+5^2 is 89 and it isn’t a perfect square
