1)
i) Reflection about y axis i.e. x=0
ii) Horizontal shrink by scale factor 4
iii) vertical shift by 4 units up.
-----------------------------------
2) f(x) passes through (1,-1) and (0,1)
So slope = (1+1)/(0-1) = -2
Using point slope form equation of f(x) is
y-1 = -2 (x-0) or y = -2x+1
g(x) passes through (0,-1) and (1,1)
Slope = (2/1) = 2
So using point slope form g(x) is
y-1=2x
Hence we find that y-1 = -2x is transformed into y-1 = 2x
i.e. there is a reflection of f(x) on the line y =1

Triangles (1/2 base x height)- 1/2(6) x 8 = 24 each
one side (length x height)- 6.5 x 8 = 52
one side (length x height)- 6.5 x 6 = 39
one side (length x height)- 6.5 x 10 = 65
total 180
Answer:
-4/3
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable
The equation would be x+7x+12x = 100
solving gives x=5
12×5=60
7×35
5+35+60=100
The age/answer is 60
