The pair values below are from an inverse variation. find the missing value

(8,,y)

The inverse variation formula is xy = k

In the first set of values you have x and y so you can solve for k:

8 x 11 = k

k = 88

Now in the second set of values you have x and we have k from the first set so we have:

10 x y = 88

Solve for y by dividing both sides by 10:

y = 88 /10

y  = 8.8

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)
