Answer:
36
Step-by-step explanation:
Basically it is = 9 x 4
Multiply the numbers
 = 9 ⋅ 4
 = 36
Solution = 36
aka
y = 36
 
        
             
        
        
        
In this equation, we are solving for f. The first thing we have to do is get rid of the denominator, so we have to multiply both sides by 9, which leaves us with 9C=5*(f-32). Then we divide both sides by 5, which is 9/5C=f-32. The last thing we have to do is add 32 to both sides to isolate f, which gives us our final equation of (5/9)C+32=f. 
        
             
        
        
        
Answer:
0
Step-by-step explanation:
We can find the slope by using
m = (y2-y1)/(x2-x1)
    = (10-10)/(1-4)
    = 0/-3
   =0
 
        
             
        
        
        
The answers that apply are Triangles, Squares, and Rectangles. Because when you look at the base of the pyramid more closely, they are maded of 3 different kinds of shapes.
        
             
        
        
        
Answer:
1) {y,x}={-3,-23}
2) {x,y}={7,-9/2}
Step-by-step explanation:
Required:
- Solve systems of equations
1) y - x = 20, 2x - 15y = -1
Equations Simplified or Rearranged :
[1]    y - x = 20
   [2]    -15y + 2x = -1
Graphic Representation of the Equations :
x + y = 20        2x - 15y = -1  
Solve by Substitution :
// Solve equation [1] for the variable  y 
  [1]    y = x + 20
// Plug this in for variable  y  in equation [2]
   [2]    -15•(x +20) + 2x = -1
   [2]     - 13x = 299
// Solve equation [2] for the variable  x 
 [2]    13x = - 299 
   [2]    x = - 23 
// By now we know this much :
   y = x+20
    x = -23
// Use the  x  value to solve for  y 
    y = (-23)+20 = -3 
Solution :
 {y,x} = {-3,-23} 
2) 25-x=-4y,3x-2y=30
Equations Simplified or Rearranged :
   [1]    -x + 4y = -25
   [2]    3x - 2y = 30
Graphic Representation of the Equations :
    4y - x = -25        -2y + 3x = 30  
Solve by Substitution :
// Solve equation [1] for the variable  x 
   [1]    x = 4y + 25
// Plug this in for variable  x  in equation [2]
  [2]    3•(4y+25) - 2y = 30
   [2]    10y = -45
// Solve equation [2] for the variable  y 
   [2]    10y = - 45 
   [2]    y = - 9/2 
// By now we know this much :
   x = 4y+25
    y = -9/2
// Use the  y  value to solve for  x 
   x = 4(-9/2)+25 = 7 
Solution :
 {x,y} = {7,-9/2}
