Answer:
E, D
Step-by-step explanation:
rate of change is the slope
slope is change in y over change in x
the slope of the graph is (3/2)
E has a slope of 1/2 which is less than 3/2
D has a slope of 1 which is also less than 3/2
Answer:
<em>s</em> = 87.5
Step-by-step explanation:
We start with 170 + 35 - 5 = 2<em>s</em> + 25
We want to find the value of <em>s. </em>Since one side of the expression (170 + 35 - 5) isn't simplified yet, that's what we should start with.
Evaluate: 170+ 35 - 5
170 + 35 - 5 = 200
Now our equation is 200 = 2<em>s</em> + 25
Solve using algebraic methods:
Start by subtracting 25 from both sides of the equation to get:
175 = 2<em>s</em>
Then, divide both sides by 2:
87.5 = <em>s</em>
The final answer you get should be <em>s </em>= 87.5
Hope this helps!

Answer: a) 70 mph
b) 80 mph
Step-by-step explanation:
Given that Kayleen left home at noon and drove to boston.she got there at 4:00. Then time spent will be 4 hours . Noon means 12pm
Distance covered = 280 miles kayleens average speed will be
Speed = distance/time
Speed = 280/4 = 70 mph
Given that Elijah was already 40 miles closer than Kayleen was when she started
Distance covered by Elijah will be
Distance = 40 + 280 = 320
Time = 4 hours
Speed = 320/4 = 80 mph
