Use Pythagoras theorem
Hypotenuse²=Base²+ Height ²
H²=(8)²+(6)²
H²=64+36
H²= 910
H²=10√91 cm Solution
, this is best fit. But the best fit for this graph is variable b
Answer: the average speed is 7.5 mph or at least im pretty sure
Step-by-step explanation:
This is because if you make the 2 miles at 6 mph to 1 mile at 3 mph then you get 1 mile at 3mph and 1 mile at 12 mph. now that you have the unit rates of these you can add them. 1 + 1 = 2 miles and 3 + 12 = 15 mph now divide this by two and you get 7.5 mph per mile.
I hope this helped, if it did could you give me a good rating? lol
Answer:
The value of x in terms of b is: 
The value of x when b is 3 is: x = -1
Step-by-step explanation:
We are given the function: 
First we need to find
The value of x in terms of b
We need to find value of x
Multiply -2 with terms inside the bracket
Subtract 10 from both sides
Divide both sides by -2b
So, The value of x in terms of b is:
The value of x when b is 3
We have the equation for the value of x in terms of b:
Put b = 3
So, The value of x when b is 3 is: x = -1
