10x®y 12which expression is equivalent to 7-2.. 6? assume x+0.y* 0.

For this case we must find an expression equivalent to:

We have to:

Now, by definition of division of powers of equal base, we put the same base and subtract the exponents. Rewriting the expression we have:

Option B

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
