Answer:

Step-by-step explanation:
The standard form of this equation is

m stands for the gradient or the slope, and c represents the y-intercept

 
        
             
        
        
        
15 I helped someone with this question already so I know its right
        
                    
             
        
        
        
10*3 = 30 feet 
30 ft*12 =360 inches
2ft *12 in=24 inches
360 +24 +1=385 inches

<u><em>Answer:</em></u>either y = 4.5
or y = -4.5
<u><em>Explanation:</em></u>To get the solution, we will need to isolate the y on one side of the equation.
<u>This can be done as follows:</u>
4y</span>²<span> = 81
</span>

<span>
y</span>²<span> = 20.25
y = +/- </span>√(20.25)<span>
either y = +</span>√<span>(20.25) = 4.5
or y = -</span>√<span>(20.25) = -4.5
Since there are no restrictions on the value of y, therefore, both answers would be accepted
Hope this helps :)</span>
 
        
        
        
X^2 + y^2 - x^2 +y^2
That would be (1x+1y)-(1x+1y)
