F(x)=2x-10
y=2x-10
x=2y-10
x+10=2y-10+10 (add both sides by 10)
2y=x+10
2y/2=x+10/2 (divide both sides by 2)
y=1/2x+5
Final Answer: f^-1(x)=1/2x+5
-5x + 2y - 4 = 0
= 5x - 2y + 4 = 0
2x 3.50 = $7 notebook sale 1x 3.00 = $3 pen sale Total sale = $10.00 less $1.00 profit To find percentage of profit $1.00/$10.00 = .10 or 10%
Answer:7996.33774627 rounded to the nearest ten is
Step-by-step explanation:8,000, hope this helps
The distance formula is d=√(x2-x1)² + (y2-y1)²
So... d =8.06226
