Step-by-step explanation:
Answer:
35 hectometers
Step-by-step explanation:
1 kilometer=10 hectometers
3 1/2=7/2
7/2*10=35
The rate of change in this case is the speed of his car or how many miles he drives in one hour.
He drives 110 miles in 4 hours, which means he will drive 110/4 miles in 1 hour because 4 hours is four times greater than 1 hour.
110/4=27.5 miles
27.5 miles in one hour or 27.5 mph
answer: 27.5 mph
Question 1:
Sub the coordinates in for x and y
Y=-6x + b
1=-6(-4) +b
1= 24 +b
-23=b
Final answer: Y=-6x -23
Repeat for question 2
Question 3:
Slope = y2-y1/x2-x1
8-11/2- -4
-3/6= -0.5
Slope is -0.5
Sub x and y into equation
Y=-0.5x +b
11=-0.5(-4) +b
11=2+b
9=b
Y=-0.5x +9
Repeat for question 4
