Answer:
B
Step-by-step explanation:
All you have to basically do on this one is go backwards.
The beginning equation is 4x+4=12, so to first revesre the adding we are going to use 12, the product, and subtract 4 from it (since that is what was added).
12-4=8
Now you need to reverse the times 4, so to do that just divide instead because that is the invese of multiplication.
8/4=2
Now you have 2, which is the variable, x. To make sure this is right you can just put it into the equation and see if 4x2+4 is 12
Hope this helped!
 
        
             
        
        
        
Answer:

Step-by-step explanation:
 
        
             
        
        
        
Radius = 3 m
Cylinder Volume =<span>  </span><span>π <span>• r² • height
</span></span>
Cylinder Volume =<span>  3.14159 * 3^2 * 5
</span><span><span><span>Cylinder Volume =<span>  </span>141.372
</span></span></span>OR  PI * 45
        
             
        
        
        
Answer:
-2
Step-by-step explanation:
1) Look at the y-intercept. The line crosses the y-axis at (0,7)
Follow it down, it goes down two and over one to directly intersect the grid. 
Rise over run = 2/1
2/1 = 2
However, the line is negative, as it's sloping down from the left to the right, making the slope -2
