Answer:
-439
Step-by-step explanation:
(s circle t) (negative 7) is a notation for a compound function.
A compound function is a function that has as an argument another function.
Another notation for this compound function is s(t(-7)), that is, the result of the function t(-7) is the value that will be used in the function s(x).
So, first we calculate the value of t(-7):
t(x) = 3x
t(-7) = 3*(-7) = -21
Now, we apply this value for s(x):
s(x) = 2 - x2
s(t(-7)) = s(-21) = 2 - (-21)^2 = 2 - 441 = -439

Answer:
The missing reason in the proof is transitive property
Step-by-step explanation:
<u>Statement </u> <u>Reason </u>
1. x ∥ y w is a transversal 1. given
2. ∠2 ≅ ∠3 2. def. of vert. ∠s
3. ∠2 ≅ ∠6 3. def. of corr. ∠s
4. ∠3 ≅ ∠6 4. ??????????
From the statements 2 and 3
The previous proved statement to make use of the transitive property reason or proof
∴ 4. ∠3 ≅ ∠6 4. transitive property
Note: the transitive property states that: If a = b and b = c, then a = c.
