Answer: Two solutions
Step-by-step explanation:
1. x =(-2-√-76)/-8=(1+i√ 19 )/4= 0.2500-1.0897i
2. x =(-2+√-76)/-8=(1-i√ 19 )/4= 0.2500+1.0897i
X = -1, y = 5. Hope this helps
Answer:
5
Step-by-step explanation:
The sum to n terms of a geometric sequence is
=
where a is the first term and r the common ratio
The expression inside the summation is
4 ← the nth term of a geometric sequence
with a = 4 and r = , then
=
=
= ( )
=
= 5
Answer:
<u>m = 8</u>
<em><u>Let's solve your equation step-by-step.</u></em>
−88=−3(4m+5)−(1−3m)
<em><u>Step 1: Simplify both sides of the equation.</u></em>
<em>−88=−3(4m+5)−(1−3m)</em>
<em>−88=−3(4m+5)+−1(1−3m)(Distribute the Negative Sign)</em>
<em>−88=−3(4m+5)+(−1)(1)+−1(−3m)</em>
<em>−88=−3(4m+5)+−1+3m</em>
<em>−88=(−3)(4m)+(−3)(5)+−1+3m(Distribute)</em>
<em>−88=−12m+−15+−1+3m</em>
<em>−88=(−12m+3m)+(−15+−1)(Combine Like Terms)</em>
<em>−88=−9m+−16</em>
<em>−88=−9m−16</em>
<em><u>Step 2: Flip the equation.</u></em>
<em>−9m−16=−88</em>
<em><u>Step 3: Add 16 to both sides.</u></em>
<em>−9m−16+16=−88+16</em>
<em>−9m=−72</em>
<em><u>Step 4: Divide both sides by -9.</u></em>
<em>−9m/−9 = −72/−9</em>
<u>m=8</u>
