Answer:
B
Step-by-step explanation:
Answer:
y+4=-2/3 (x+1)
Step-by-step explanation:
-1 = x1
-4 = y1
m = -2/3
slope - intercept form = y - y1 = m(x - x1)
y-(-4) = -2/3(x - (-1))
y + 4 = -2/3(x +1)
We can model the function between a and b as a linear function of negative slope because it is a short interval and the change is not very significant.
We have then that the average rate of change in that interval is:
m = (f (a) - f (b)) / (a-b)
Substituting the values:
m = (34.25 - 26) / (2.5-3.6)
m = -7.5
Negative, because the function decreases in that interval.
Answer:
a reasonable estimate of the average rate of change of the height of the rocket, in meters per second, between a and b seconds is:
m = -7.5 m / s
Answer:
converting the equation to improper fraction
31/5+(-38/5)
31/5-38/5( the plus sign affected the minus sign inside of the bracket which is+*- = -)
multiply both terms by 5
31-38= -7
There are Zero possible solution to this system of equations.
