Answer:
Did you want me to simplify the expression???
Step-by-step explanation:
3f+5b+3d+8
By Cramer's rule, the solution can be found as the ratio of determinants. The numerator is the matrix with the right-side constants replacing the coefficients of the variable of interest. The denominator is the matrix of coefficients.
![x=\displaystyle\frac{det\left[\begin{array}{cc}-26&-6\\13&2\end{array}\right]}{det\left[\begin{array}{cc}-2&-6\\5&2\end{array}\right]}=\frac{(-26)(2)-(13)(-6)}{(-2)(2)-(5)(-6)}\\\\=\frac{26}{26}=1\\\\y=\frac{det\left[\begin{array}{cc}-2&-26\\5&13\end{array}\right]}{26}=\frac{(-2)(13)-(5)(-26)}{26}\\\\=\frac{104}{26}=4](https://tex.z-dn.net/?f=%20x%3D%5Cdisplaystyle%5Cfrac%7Bdet%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D-26%26-6%5C%5C13%262%5Cend%7Barray%7D%5Cright%5D%7D%7Bdet%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D-2%26-6%5C%5C5%262%5Cend%7Barray%7D%5Cright%5D%7D%3D%5Cfrac%7B%28-26%29%282%29-%2813%29%28-6%29%7D%7B%28-2%29%282%29-%285%29%28-6%29%7D%5C%5C%5C%5C%3D%5Cfrac%7B26%7D%7B26%7D%3D1%5C%5C%5C%5Cy%3D%5Cfrac%7Bdet%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D-2%26-26%5C%5C5%2613%5Cend%7Barray%7D%5Cright%5D%7D%7B26%7D%3D%5Cfrac%7B%28-2%29%2813%29-%285%29%28-26%29%7D%7B26%7D%5C%5C%5C%5C%3D%5Cfrac%7B104%7D%7B26%7D%3D4%20)
The solution is ...
... B. (1, 4)
Answer:
1) a 130° - (360 - (50×2)) /2
B 50° - opposite angles
2) a 25° - 90° - 65 = 25 °
B 270° - 360° - 90° = 270°
3) a ) 60° - 180° - 120° = 60° (there are 180° in a straight line)
B) 90° - 180°-90° = 90°
Well its D. 5x^9/10.y^1/3
Answer:
97.79
Step-by-step explanation:
1062.98 * 0.092 = 97.79416
To the nearest hundredth would be to the second 9. Since 4 is less than 5 just drop the 4 and anything after it.
