Can you help me i really need it

8

Step-by-step explanation:

1) Add -11 plus 19 which should give you 8.

2) Check your answer by subtracting 8 - 19 = -11

Heya there!

Let us learn that we want that variable to be by itself.

To get the variable (b) by itself we need to do some work.

Solving for B:

As we need to get B by itself, we beed to remove the "-19".

To do that, we have to +19 since the -19 is a negative.

This allows us to have B by itself.

b - 19 = -11

   +19    +19 to both sides ; whatever action we do to one side we do to the other.

Now, the equation should look like b = 8

We got b = 8 from the adding +19 to both sides. -11 + 19 = 8

Therefore, we are left with b = 8.

Thanks for using !

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
