Answer:
1km per minute
Step-by-step explanation:
Given the table in the picture :
The average rate of change over the interval from 8 to 15 minutes will be :
Change in distance / change in time
Change in distance between 8 and 15 minutes :
Distance d1 at 8 minutes t1 = 7km
Distance d2 at 15 minutes t2 = 14km
Average rate of change = (d2 - d1) / (t2 - t1)
Average rate of change = (14 - 7)km / (15 - 8)min
Average rate of change = 7km / 7minutes
Average rate of change = 1km per minute
Answer:
a) reflection across the x-axis, shift 8 units left
b) vertical stretch of 2, reflection across the y-axis, shift up 1
Step-by-step explanation:
The negative sign outside the square root represents a reflection across the x-axis, and the +8 inside represents a shift 8 to the left
The 2 outside the square root represents a vertical stretch of 2, and the negative sign inside the square root represents a reflection across the y-axis. The +1 at the end represents a shift up 1
Answer:
x=4
Step-by-step explanation:
19+3x=3(x-5)
do rainbows
