Answer:
7 is the (constant) coefficient of 1/y, but no, it is not the coefficient of y
Step-by-step explanation:
7/y can be rewritten as 7(1/y) or as 7(y^[-1]).  In this case, yes, 7 is the (constant) coefficient of 1/y, but no, it is not the coefficient of y.

Answer:
OPTION A: 2x + 3y = 5
Step-by-step explanation:
The product of slopes of two perpendicular lines is -1.
We rewrite the given equation as follows:
2y = 3x + 2
⇒ y = 
The general equation of the line is: y = mx + c, where 'm' is the slope of the line.
Here, m =  .
.
Therefore, the slope of the line perpendicular to the line given =  because
 because  .
.
To determine the equation of the line passing through the given point and a slope we use the Slope - One - point formula which is:
                                   y - y₁ = m(x - x₁)
The point is: (x₁, y₁) = (-2, 3)
Therefore, the equation is:
y - 3 =  (x + 2) $
(x + 2) $
⇒ 3y - 9 = -2(x + 2)
⇒ 3y - 9 = -2x - 4
⇒ 2x + 3y = 5 is the required equation.
 
        
                    
             
        
        
        
Answer:
0.012
Step-by-step explanation:
Linear approximation says that, 

For a cube the surface area is  .
. 
So the side is 1.0 inch in, the surface area is  square inches.
 square inches.  
In Linear approximation means you ignore the term  , if
 , if  is a small number, because then
 is a small number, because then  will be a very smalle number and that does not contribute much to the error.
 will be a very smalle number and that does not contribute much to the error.  
So the surface area is approximately, 
 
So here, 
The error in the area is approximately, 

So the error is 0.012.
