Step-by-step explanation:
6x2 - x + 3 - (-5x2 + 10x - 1)
6x2 - x + 3 + 5x2 - 10x + 1
Solving like terms
11x2 - 11x + 4
It should be 75000. I don’t know. I looked this up but I still hope this helps!
Answer:
Option A. 5
Step-by-step explanation:
From the question given above, the following data were obtained:
First term (a) = –3
Common ratio (r) = 6
Sum of series (Sₙ) = –4665
Number of term (n) =?
The number of terms in the series can be obtained as follow:
Sₙ = a[rⁿ – 1] / r – 1
–4665 = –3[6ⁿ – 1] / 6 – 1
–4665 = –3[6ⁿ – 1] / 5
Cross multiply
–4665 × 5 = –3[6ⁿ – 1]
–23325 = –3[6ⁿ – 1]
Divide both side by –3
–23325 / –3 = 6ⁿ – 1
7775 = 6ⁿ – 1
Collect like terms
7775 + 1 = 6ⁿ
7776 = 6ⁿ
Express 7776 in index form with 6 as the base
6⁵ = 6ⁿ
n = 5
Thus, the number of terms in the geometric series is 5.
Answer:
a = 7
b =?
c = 1/2
a + by = 0
7 + b × 1/2 = 0
7 + 1/2 b = 0
1/2 b = - 7
b = -7 × 2
b = - 14
a + by
= 7 + - 14 × 1/2
= 7 -14/2
= 7 - 7
= <u>0</u>
Step-by-step explanation:
Id.k if you forgot to write the value of b or not, since the value of b is not given, this will be ur answer.
Yes because you use the distributive property
