Answer:
$909.50
Step-by-step explanation:
$850 x 7% = $59.50 (tax amount)
850 x (1+ 0.07) = $909.50
 
        
             
        
        
        
Answer: x = 4
Step-by-step explanation:
2x - 3 + 4x = 21
6x - 3 = 21 
6x - 3 (+3)  = 21 (+3)
6x = 24
24/6
x = 4
 
        
                    
             
        
        
        
A = 5, -10
B = 1, 8
C = 5, -7
        
                    
             
        
        
        
Rewrite the equations of the given boundary lines:
<em>y</em> = -<em>x</em> + 1  ==>  <em>x</em> + <em>y</em> = 1
<em>y</em> = -<em>x</em> + 4  ==>  <em>x</em> + <em>y</em> = 4
<em>y</em> = 2<em>x</em> + 2  ==>  -2<em>x</em> + <em>y</em> = 2
<em>y</em> = 2<em>x</em> + 5  ==>  -2<em>x</em> + <em>y</em> = 5
This tells us the parallelogram in the <em>x</em>-<em>y</em> plane corresponds to the rectangle in the <em>u</em>-<em>v</em> plane with 1 ≤ <em>u</em> ≤ 4 and 2 ≤ <em>v</em> ≤ 5.
Compute the Jacobian determinant for this change of coordinates:

Rewrite the integrand:

The integral is then
