Answer:
infinitely many solutions
Step-by-step explanation:
0 = 0 ← is a true statement.
Indicates that the 2 lines are the same line, that is one lying on top of the other.
Thus the system has an infinite number of solutions
Answer:
Step-by-step explanation:
∑⁴ₙ₌₁ -144 (½)ⁿ⁻¹
This is a finite geometric series with n = 4, a₁ = -144, and r = ½.
S = a₁ (1 − rⁿ) / (1 − r)
S = -144 (1 − (½)⁴) / (1 − ½)
S = -270
If you wanted to find the infinite sum (n = ∞):
S = a₁ / (1 − r)
S = -144 / (1 − ½)
S = -288
