Use the formula for average rate of change over an interval of two points:
We have two points: (-2, -1) and (0, -1). Plug the values into the formula:
The average rate of change over the interval [-2,0] is
0.
Answer:
9
Step-by-step explanation:
Let corn tortillas be represented by c, flour tortillas be represented by f and the total number of packages be t
such that
t = c + f .... eq 1
ratio of c to t = 7 : 16 = 7/16
Therefore, t = 16, c = 7
substitute the value of t in eq 1
16 = 7 + f
f = 16 - 7
f = 9
Answer:
D
Step-by-step explanation:
Given that
f(x)=-2x – 1
g(x) = -1/2x+1/2
I The function f( g(x)) = x for all real x.
-2(-1/2X + 1/2) - 1
X - 1 - 1
X - 2
II. The function glAx)) = x for all real x.
- 1/2( -2X - 1 ) + 1/2
X + 1/2 + 1/2
X + 1
III. Functions fand g are inverse functions
Inverse of f(x)
Y = -2x - 1
X = - 2Y - 1
- 2Y = X + 1
Y = - 1/2X - 1/2
Therefore, none of the above answers is correct.
The correct answer is therefore D
Answer:
Keith's unit rate of change of dollars with respect to time is $1500.
Step-by-step explanation:
It is given that Keith is saving money for a car.
Year 1: 1500
year 2: 3000
year 3: 4500
Let y be the saved amount after x year.
The coordinate pairs according to the given table are (1,1500), (2,3000) and (3,4500).
The formula for rate of change is
Consider any two coordinate pairs.
Let as consider (1,1500) and (2,3000). So, Keith's unit rate of change of dollars with respect to time is
Therefore, Keith's unit rate of change of dollars with respect to time is $1500.
