Answer:

Step-by-step explanation:

we can use the distributive property and get

and we can add like terms

and know we divide both sides by 16.5

and doing the dvision we get that

 
        
             
        
        
        
Answer:

Step-by-step explanation:
Given the system of equations:


In order to find the y coordinate of the solution we must first find the solution to this system of equations. We first start by solving one of the given equations and then substitute the answer of that into the second equation and further solve to get the final answers.




















Hope this helps.
 
        
             
        
        
        
Please note that dilation does not affect angles. Thus, if an image is dilated the angle remains the same and does not change. 
Therefore, even if 
 is dilated to 
 by a factor of 1.5 (or by any factor for that matter), the linear dimensions of the original triangle 
 will either get stretched or get shrunk by a factor of 1.5 but the angles of the original triangle will not be affected in any case.
Please note that this is true for all two dimensional geometric shapes.
