Answer:
The morning of my 50th birthday in May I did something I had not tried in a long time. I dropped to the floor and did 50 push-ups, one for each year. I had to break it up into sets and the last few where shaky, but I did it.
And it felt great.
As a new member to the 50-plus club, I realized this bread-and-butter exercise still works wonders as a snapshot of your fitness. In addition, it might predict your risk for cardiovascular problems. In a study of male firefighters published in the February 2019 issue of JAMA Network Open, men who could complete at least 40 push-ups over 30 seconds had a significantly lower risk of heart attack, heart failure, or other cardiovascular problems over the next 10 years compared with men who were able to complete less than 10.
“How many you can do at one time offers a real-time measurement of your strength and muscular endurance and is an easy tool to help you improve,” says Dr. Edward Phillips, assistant professor of physical medicine and rehabilitation at Harvard Medical School. “You can do them anywhere and at any time. All you need is your body weight and a few minutes.”

Answer:
(-4 , 6)
Step-by-step explanation:
3x +4y - 12=0
x = 1/3 × (12-4y)
y² = 9 × 1/3 × (12-4y) = 36 -12y
y² + 12y -36 =0
(y -6)² = 0
y = 6
x = -4
