Which of the following satisfies 5u+1= -4 i) u=3 ii) u=7 iii) u= 1/5 iv) u= -1

Solution,

5u+1=-4

or,5u=-4-1

or,5u=-5

or,u=-5/5

u=-1

Hope it helps

Good luck on your assignment..

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
