30 The set of ordered pairs below represents a linear function.
{(1,104), (2,11%). (2,3)}
If y = 20, what is the value of x?
(Explain all of your steps in the box below. You can also use Scratchpad to draw.)
Note: In the right of the answer box, select M to input mathematical symbols and T for text.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

      2

  2 is to go somewhat to the top right of a because it is squared    

v= a h/3

: d

step-by-step explanation:

a magnifying glass is a convex lens which produces a magnified image of an object. for a magnified image to be observed the distance between the object and the lens has to be shorter than the focal length of the lens.
