Answer:
Rate of change is the highest in interval 4 ≤ x ≤ 6.
Step-by-step explanation:
The rate of change of a graph is defined as the slope of the graph at that point.
We have to find in which interval the the graph has the highest rate of change.
From the graph we can see that different intervals has different slopes.
From the graph we can see that the steepness of the graph is the highest in the interval 4 ≤ x ≤ 6.
Hence the rate of change is the highest in this interval.
Answer:
x = 11
Step-by-step explanation:
First, subtract 324 from both sides:
36x + 324 = 720
36x = 396
Divide each side by 36:
x = 11
So, the answer is x = 11
4(4) -4 = 16-4 = 12
She was wrong because she thought that x= 6
The m is always the slope and the b is the y intercept
