Me i’m stuck. will give brainliest!

Triangle SET is similar to triangle SAR, so corresponding sides have the same ratio. This means

... ST : SR = ET : AR = 8.19 : 6.37

Then ST : TR = 8.19 : (6.37+8.19) = 8.19 : 14.56

Using division symbols, this is

... ST/TR = 8.19/14.56

Multiplying by TR gives

... ST = TR×(8.19/14.56) = 20.8×8.19/14.56

... ST = 11.7

check the picture below.

so, therefore, the triangles are similar by AA.

now, notice the length RT = 20.8, thus whatever ST might be, RS picks up the slack from the 20.8, namely RS = 20.8 - ST. Then we can use proportions from the corresponding sides.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
