1. 0.5625
2. 144
3. -2
4. -16
Answer:
2 minutes
Step-by-step explanation:
You can make an equation to model the question.
y=60 initial starting value,
y=(750-720)x, plug in 60 for y,
60=30x, x = 2 minutes
First you want to find the slope. Pick any two points. (150,200) and (300,100) x2-x1/y2-y1
300-150=150
100-200=-100
150/-100= -1.5
Y=mx+b. M is the slope b is the y intercept
Y=-1.5x+300
Answer:
24
