Answer:
f(x) = y
Step-by-step explanation:
f(x) always equals y, so the equation would be y = 7. therefore, I am pretty sure that x = y, but you may want to wait to ask your teacher. If there is more detail, message me!
 
        
             
        
        
        
Answer:
What is the question am I supposed to calculate the slope? If so then the answer is 5/-3
Step-by-step explanation:
  
 
        
             
        
        
        
The number is 142 
you first make an equation ;
86+x=2x-56
Add 56 to both sides
142+x=2x
Subtract x from both sides
142=x
        
             
        
        
        
The area <em>A</em> of a trapezoid with height <em>h</em> and bases <em>b</em>₁ and <em>b</em>₂ is equal to the average of the bases times the height:
<em>A</em> = (<em>b</em>₁ + <em>b</em>₂) <em>h</em> / 2
We're given <em>A</em> = 864, <em>h</em> = 24, and one of the bases has length 30, so
864 = (<em>b</em>₁ + 30) 24 / 2
864 = (<em>b</em>₁ + 30) 12
864 = (<em>b</em>₁ + 30) 12
72 = <em>b</em>₁ + 30
<em>b</em>₁ = 42
 
        
             
        
        
        
Answer:
The slope is 3. 
Step-by-step explanation:
A direct variation function will always go through the origin point (0, 0). 
Therefore, we have the two points (0, 0) and (-2, -6). 
We can use the slope formula to find the slope: 

Substitute and evaluate: 

Therefore, the slope of the function is 3. 
To graph, simply plot (0, 0) and (-2, -6) and draw a line connecting them. This is shown below.
