Answer: AB/y = BC/z = AC/x
Step-by-step explanation:
Side AB corresponds to side y, side BC corresponds to side z, and side AC corresponds to side x.
1) Given
Since (0.5,8) lies on f(bx) ,
Divide with on both sides
= 64
Hence b=4.
2) Given (1,3) lies on y=f(x) plugin x=1 and y=3
that is f(1) = 3
We can find corresponding point for that in y=-2f(x) by plugging in x=1.
That is y= -2f(1) = -2*3 = -6
Hence point is (1,-6)

k/9-1=12
We move all terms to the left:
k/9-1-(12)=0
We add all the numbers together, and all the variables
k/9-13=0
We multiply all the terms by the denominator
k-13*9=0
We add all the numbers together, and all the variables
k-117=0
We move all terms containing k to the left, all other terms to the right
k=117
