Okay, for this one, I recommend setting up a proportion table. First you will figure out that her heart beats 225 times approximately in 3 minutes (no duh), and literally all you have to do is divide 225 by 3. That's all! Then you'll get 75! I hope this helped you!
Answer:
x = -5
Step-by-step explanation:

When y=0, t=1
so after 1 second the hammer land on the ground.
Divide by 2 on each side: x+2y=10

x-intercept: (10, 0)
y-intercept: (0, 5)
Draw those two points, connect, and extend.
