7)
17x + 3 = 54
17x = 51
x = 3
4y - 3 = 57
4y = 60
y = 15
8)
4x - 3 = 45
4x = 48
x = 12
180 - 45 - 41 = 84
11y + 6 = 94
11y = 88
y = 8
Which of the following is the equation of a trend line for the scatter plot below? a. y = 3/2x + 1/2
Let's find the slope of this line.
slope=change in y/change in x
slope=8500-8000/0-100=500/-100=-5
So that means the plane is falling 5 meters per second.
So, the place will fall 50 meters in 10 seconds.
