Answer:32
Step-by-step explanation:firs we multiply 5*4 =20 .then we subtract 2-1=1 add those numbers 20+1=21 and then add 11 which equals 32
 
        
             
        
        
        
Answer:
A.  y  =  - 1
 - 1
Step-by-step explanation:
Given parameters: 
Equation of the line: 
        5x + 2y = 12
Coordinates = -2, 4
Unknown: 
The equation of the line parallel to this line = ? 
- To solve this problem, first, we need to find the slope of the given line. 
      Every linear equation have the formula:  y = mx + c
      m is the slope of the line, c is the y- intercept
            5x + 2y = 12
  Express this equation as y = mx + c
                  2y = -5x + 12
                     y =  + 6
  + 6
The slope of this line is 
- Now, any line that is parallel to another will not cut or cross it at any point. This simply implies they have the same slope. 
                   Slope of the line parallel is 
- Our new line will also take the form y=mx + c, 
           Coordinates = -2, 4, x = -2 and y = 4 
                      m is 
Now let us solve for C, the y-intercept; 
                      4 = - 2 x  + C
  + C
                       4 = 5  + C
                        C = -1
The equation of the line is therefore; 
                  y  =  - 1
 - 1
 
        
             
        
        
        
Answer:
p(x) = 7x - 20
Step-by-step explanation:
A company makes a profit selling goods when the revenue taken in from the sales is greater than the cost of those goods:  p(x) = r(x) - c(x) > 0.
In this case the revenue function is r(x) = 12x; the cost function is c(x) = 5x + 20, and the profit function is p(x) = 12x - (5x + 20), or:
p(x) = 12x - 5x - 20, or
p(x) = 7x - 20
 
        
             
        
        
        
5(100)= 500
5(90)= 450
5(8)= 40
500+450+40= 990
The answer is 990. Hope this helps!
        
             
        
        
        
Here, 3x + 6x = 90
9x = 90
x = 90/9
x = 10
In short, Your Answer would be 10
Hope this helps!
