If relationship between X and y is given by 4x+5y=10 and range of X is...
Explanation:

  • The given equation is 4x+5y=10.

  • To find the range of y, we need to isolate y on one side of the equation.

  • Let's start by subtracting 4x from both sides of the equation:


    • 4x + 5y = 10

    • 5y = 10 - 4x


  • Now, divide both sides of the equation by 5:


    • y = (10 - 4x)/5


  • So, the range of y will depend on the range of x.

  • Given that the range of x is 15, we can substitute x = 0 and x = 15 to find the minimum and maximum values of y:


    • When x = 0:


      • y = (10 - 4(0))/5 = 2


    • When x = 15:


      • y = (10 - 4(15))/5 = -2



  • Therefore, the range of y is from 2 to -2.

  • However, since we are looking for the absolute range of y, we take the absolute values of these numbers:


    • Range of y = |-2| - |2| = 2


  • So, the range of y is 2.

  • Therefore, the correct answer is (a) 10.

If relationship between X and y is given by 4x+5y=10 and range of X is...
5y=10-4x
y=10/5-4x/5
Ry=|b|*Rx
=|-4/5|*15
=4/5*15
=12
therefore (c)is the answer that is 12.
