Answer:
hello
bring the side of the first part of the triangle then you can to bring the (x) of the second traingle
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:
172.5 mg/dl
Step-by-step explanation:
Given the equation y= -2.5x + 222.5, where 'x' is the time spent exercising in minutes. If we want to know the amount of cholesteron for a person exercising 20 minutes a day, we just have to subtitute 20 into the equation for x.
So we have: y= -2x + 222.5 → y= -2.5(20 minutes) + 222.5 = 172.5 mg/dl
