Final Answer:
The value of j in the equation VT + V1 + 14 = 3V7 + 10 + j, where V= 7, V1 = 4, V7 = -9, T = 5 is 70. Option B is answer.
Explanation:
Substituting the given values in the equation, we get:
V(T) + V1 + 14 = 3V7 + 10 + j
7(5) + 4 + 14 = 3(-9) + 10 + j
35 + 18 = -27 + 10 + j
53 = j - 17
j = 53 + 17
j = 70
Therefore, the value of j when V=7, V1=4, V7=-9 and T=5 is 70. Option B is answer.
