 -2

Step-by-step explanation: f(x)≈ -0.86x+13.5

   putting x=18 in f(x), we get

     f(x)≈ -0.86×18+13.5

  ⇒      f(x)≈ -15.48+13.5

  ⇒      f(x)≈ -1.98

  ⇒      f(x)≈ -2

Option 2 - f(x)=-2

Step-by-step explanation:

Given : A line of best fit is f(x) ≈ −0.86x + 13.5 for the set of points in the table.

To find :  What is a good approximation for the value of the function, f(x), when x = 18?

Solution :

We have given the function,

The best fit for the value x=18, f(x) is

Approximately, For the value of x=18, f(x)=-2

Therefore, Option 2 is correct.

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
