Barry will use the distance formula:
d = √[(x₂ - x₁)² + (y₂ - y₁)²]
d = √[(4 - 3)² + (7 - 1)²]
d = 6.08 units
Answer:
4. B
5.
Step-by-step explanation:
You have to complete the square of (x²+18x+?) as well as for (y²-36y+?)
You will find: (x+9)² + (y-18)² = 36
& this is the standard equation requested
Answer:
15x + 9 (We combing like terms. Ex. 16x and -x)
