Answer:
-1
Step-by-step explanation:
The average rate of change is the ratio of the difference in y-values to the difference in x-values of corresponding points.
At x=-1, f(x) = (-1)^2 -(-1) -1 = 1
At x=1, f(x) = (1)^2 -(1) -1 = -1
So, points on the graph are (-1, 1) and (1, -1).
Then the change in y over that interval is -1 -1 = -2.
The change in x over that interval is 1 -(-1) = 2.
The average rate of change is ...
∆y/∆x = -2/2 = -1 . . . . average rate of change on (-1, 1)
Answer:
find the common denominator first then compare.....

Answer:
Distance between two point = 3.6 (Approx.)
Step-by-step explanation:
Given:
Coordinate;
(-4, -6) and (-1, -4)
Find:
Distance between two point
Computation:
Distance between two point = √(x1 - x2)² + (y1 - y2)²
Distance between two point = √(-4 + 1)² + (-6 + 4)²
Distance between two point = √(-3)² + (-2)²
Distance between two point = √9 + 4
Distance between two point = √13
Distance between two point = 3.6 (Approx.)
In order it goes like this
- 4^ x - 1 = 3^ (-x) - 2
- 3 x + 6 = 2^ x + 1
3^ x - 3 = 2 x - 2
so the question is the answer
Answer
Together, they have 99 marbles.
Explanation
Ravi has 33 marbles.
His brother has twice (two times) as many marbles as him. Ravi's brother has 33×2=66 marbles.
Together, they have 33+66=99 marbles.
