Solve each linear equation x+4y=18 x+8y=38

suter [353]

Answer:

Answer: {x = -2 , y = 5

Step-by-step explanation:

{x + 4 y = 18 | (equation 1)

{x + 8 y = 38 | (equation 2)

Subtract equation 1 from equation 2:

{x + 4 y = 18 | (equation 1)

{0 x+4 y = 20 | (equation 2)

Divide equation 2 by 4:

{x + 4 y = 18 | (equation 1)

{0 x+y = 5 | (equation 2)

Subtract 4 × (equation 2) from equation 1:

{x+0 y = -2 | (equation 1)

{0 x+y = 5 | (equation 2)

Collect results:

Answer: {x = -2 , y = 5

Find S15 for the geometric series 72 + 12 + 2 + +…

Sedbober [7]

$S_{15}=72+12+\cdots+\dfrac1{181398528}+\dfrac1{1088391168}$
$S_{15}=72\left(\dfrac16\right)^0+72\left(\dfrac16\right)^1+\cdots+72\left(\dfrac16\right)^{13}+72\left(\dfrac16\right)^{14}$
$S_{15}=72\displaystyle\sum_{i=1}^{15}\left(\frac16\right)^{i-1}$

$\dfrac16S_{15}=72\displaystyle\sum_{i=1}^{15}\left(\frac16\right)^i$

$\implies S_{15}-\dfrac16S_{15}=72\displaystyle\sum_{i=1}^{15}\bigg(\left(\dfrac16\right)^{i-1}-\left(\dfrac16\right)^i\bigg)$
$\dfrac56S_{15}=72\bigg(\left(1-\dfrac16\right)+\left(\dfrac16-\dfrac1{6^2}\right)+\cdots+\left(\dfrac1{6^{13}}-\dfrac1{6^{14}}\right)+\left(\dfrac1{6^{14}}-\dfrac1{6^{15}}\right)\bigg)$
$\dfrac56S_{15}=72\left(1-\dfrac1{6^{15}}\right)$
$S_{15}=\dfrac{432}5\times\dfrac{6^{15}-1}{6^{15}}=86.4$
