Answer: Endpoint = (-4,6)
Step-by-step explanation:
To find any endpoint use the formula

multiply each by 2 to simplify
take the equations and simplify
6+
= 2 -2+
= 4 =
-6 -6 +2 +2
= -4
= 6
To check use the Midpoint formula

Answer:
36 miles
Step-by-step explanation:
His entire journey, represented with a diagram, is in the shape of a right angle triangle.
We need to first find the hypotenuse of the triangle, then, add all the sides together:
hyp² = opp² + adj²
hyp² = 9² + 12²
hyp² = 81 + 144 = 225
Find the square root of both sides:
hyp = 15 miles
Therefore, adding the three sides together:
Total distance traveled = 9 + 12 + 15
Total distance traveled = 36 miles
He would ride 36 miles altogether.
Answer:
x = 
Step-by-step explanation:
Distributive Property:
3 (x - 4) = 12x
3x - 12 = 12x
Combine like terms and isolate the variable:
3x - 12 = 12x
-12 = 9x
= x
x = 
Since 9 is a factor of an unknown number, that means that that number has to be a multiple of 9. If 9 is the factor of something then that something HAS to be a multiple of 9.
