Answer:
= - 14
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 7 and d = - 3, thus
= 7 + (7 × - 3) = 7 - 21 = - 14

f(1/3) = 9
Answer:
y = 1/4 = 0.250.
Step-by-step explanation:
1. A in some part is correct, but the triangles are indeed correct, and the argument is for HL, so the answer is C
2. Are congruent by SSS (both shares a side).
