What is the common ratio of 40,12,3.6
slava [35]

Answer:

0.3

Step-by-step explanation:

Divide the second term (12) with the first term (40), and you'll get 0.3

This is correct because you get the terms in the correct order when multiplying:
(First term: 40. Common ratio: 0.3)
40 x 0.3 = <u>12</u>
<u>12</u> x 0.3<em> </em>= <em>3.6</em>

40, <u>12</u>, <em>3.6</em>

Use Cramer's Rule to solve the following system: –2x – 6y = –26 5x + 2y = 13
andriy [413]
\bf \begin{cases}&#10;-2x-6y&=-26\\&#10;\quad 5x+2y&=13&#10;\end{cases}\stackrel{\textit{determinant of the coefficients}}{D=&#10;\begin{bmatrix}&#10;-2&-6\\5&2&#10;\end{bmatrix}}\implies (-4)-(-30)&#10;\\\\\\&#10;D=-4+30\implies \boxed{D=26}\\\\&#10;-------------------------------\\\\

\bf x=\cfrac{D_x}{D}\implies x=\cfrac{&#10;\begin{bmatrix}&#10;\boxed{-26}&-6\\\\ \boxed{13}&2&#10;\end{bmatrix}}{D}\implies x=\cfrac{(-52)-(-78)}{26}&#10;\\\\\\&#10;x=\cfrac{-52+78}{26}\implies x=\cfrac{26}{26}\implies \boxed{x=1}\\\\&#10;-------------------------------\\\\&#10;y=\cfrac{D_y}{D}\implies y=\cfrac{&#10;\begin{bmatrix}&#10;-2&\boxed{-26}\\\\ 5&\boxed{13}&#10;\end{bmatrix}}{D}\implies y=\cfrac{(-26)-(-130)}{26}&#10;\\\\\\&#10;y=\cfrac{-26+130}{26}\implies y=\cfrac{104}{26}\implies \boxed{y=4}
