Answer:
x= -3
y= -5
Step-by-step explanation:
10y - 3x = -41
 +
-5y + 3x = 16
10y + (-5y) = 5y
-3x + 3x = 0
-41 + 16 = -25 
5y + 0 = -25
 y = -25/5
 y= -5
10y -3× = -41
(10×-5) - 3x = -41
- 3x = - 41 + 50
- 3x = 9
 x = -3
 
        
             
        
        
        
Answer:
my answer would be that 
x = 17.91cm
(i'm not sure about it either but it's worth a try) !!
Step-by-step explanation:
so first off, using the equation given, 
" c² = a² + b² — 2ab cos C "
we substitute the values in as, 
a = 16 
b = 30 
then for C is the angle given, which is 30° 
so the equation is now, 
c² = (16)² + (30)² — 2(16)(30) cos 30° 
now, you solve the two squared numbers and the back equation, also known as " 2ab cos C " with your scientific calculator. 
so it now equals to, 
c² = 256 + 900 — 960(0.87)
c² = 320.8 
at last, when you have " c² = 320.8 " ,
remember to square root the answer so you have a smaller value. 
so,
c equals to 

your final answer for the x value will be 17.91 
(i hope this helps!) 
 
        
             
        
        
        
 the answer is pi36 bc the formula for area is pir^2
        
             
        
        
        
Answer:
22
Step-by-step explanation:
a = 14
b = 8
therefore, you just add that and get your answer
 
        
             
        
        
        
So matrix which show equation 4x+2y=4 is  ![\left[\begin{array}{ccc}4&2&4\\12&-1&26\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D4%262%264%5C%5C12%26-1%2626%5Cend%7Barray%7D%5Cright%5D) .
 .
Given that we have an equation that is 4x+2y=4
So equation is a statement that the values of two mathematical expressions are equal (indicated by the sign =).
So in order to write this equation in matrix form we have to write it into augmented matrix 
So augmented matrix is a matrix whose elements are the coefficients of a set of simultaneous linear equations with the constant terms of the equations entered in an added column.
Therefore the matrix will be:
![\left[\begin{array}{ccc}4&2&4\\12&-1&26\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D4%262%264%5C%5C12%26-1%2626%5Cend%7Barray%7D%5Cright%5D) .
