What would the vaule of y be when x=-2

=1

The value of y varies directly with x, and y=1 when x=2.

Step-by-step explanation:

Formula for direct variation is y=kx, where k represents the constant. So, we solve for "k" first given the "x" and "y" variables.

Read "y varies directly as x" when y=2, x=10:

2 = k(10)

2  = k(10)

10      10

1

5  = k  

Now that you found "k" you can substitute that into equation with the other given variables:

y = (1/5)(-25)= -5

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons
