Rate is an expression for a change of some unit per unit of time. For this problem, we find the rate of change of the price by a simple equation which is expressed as: 

Rate = change in price / change in time
Rate = ($1.20/lb - $0.90/lb) / 5 yrs - 0
Rate = $0.06 per lb per year

Thus, the answer is B.

The equation 2y+x0 is shown on the graph below as a:
kirza4 [7]
I think it’s the red line.
So you want to put the equation into y=mx+b so you would need to subtract the x to put it on the right side so then you’ll have 2y=-x+0 then divide by 2 to get the y by itself then you’ll have y=-2x+0 that means the line would be negative and the y intercept is 0 and the only line that follows that is the red line.

Hope this helped :)

Y=? What is Y? Please help me!

Answer:   y = 6 mi.  .
______________________________________________
Explanation:
______________________________________________
Area of a triangle = (½) * (base) * (height) ;

or,  A = (½) * b * h ;  or,  A = b*h / 2 ;
_____________________________________
Given:  A = 24.3 mi ² ;
           b = 8.1 mi 
___________________
Find the height, "h" ;  (in units of "miles", or , "mi" ).
__________________________
   Plug in the known values into the formula:

24.3 mi ² = (½) * (8.1 mi) *(h) ;
_____________________________
Solve for "h" (height) ;
_____________________________
(½) * (8.1 mi) = 4.05 mi  ;
______________________________
Rewrite: 
____________________________
24.3 mi² = (4.05 mi) *(h) ;  Solve for "h" ;
_________________________________________
 Divide each side of the equation by "(4.05 mi)" ; to isolate "h" on one side of the equation ; and to solve for "h" ; 
__________________________________________
   24.3 mi²  / 4.05 mi  = (4.05 mi) *(h)  / 4.05 mi ;
                                 
              →  6 mi  = h ;  ↔  h = 6 mi. 

              →      h = y = 6 mi.
