Step-by-step explanation:
Answer: x = 20.25
Step-by-step explanation: 24 - 3.75 = 20.25
They are called transformations.
Answer:
y = -x
Step-by-step explanation:
The line has a slope of -1 and it passes through point (0,0)
Taking another point (x,y) on the line;
Slope = change in y ÷ change in x
For our case; slope = 
Cross multiplying this gives;
y = -x
20 + 4 + 3/10 + 5/100 + 7/1000
