2: They do not because the hypotenuse is larger and a^2 + b^2
3. The tiangle is acute because it has all angles smaller than 90*
12: The buillding is approximately 100 ft tall give or take. I am sorry If i am wrong on the last one
Answer:
Step-by-step explanation:
4x - 12 - 5x ≥ -1
-x - 12 ≥ -1
-x ≥ 11
x ≤ -11
For this case we have to by definition, if "y" varies directly with "x" then it is true that:

Where:
k: Is the constant of proportionality
We find the constant "k" according to the given data:

Thus, the constant of proportionality is 
Now, we find the value of "y" when 

Thus, when
, the value of y is 21.
