Answer:
(-2,-5), (0,-4), (3,5) (1,1)
Solution:
Only (0,-4) is on the line
(-2,-5), (1,1), and (3,5) is in the orange
(5,5) Isn't right because it's not on the line nor in the orange
Answer:
38 degrees
Step-by-step explanation:
By the Law of Cosines,
5² = 3² + 7² - 2(3)(7) cos A
5² - 3² - 7² = -2(3)(7) cos A
-33 = -42 cos A
cos A = 33/42
A = arccos(33/42), which is about 38 degrees.
Answer:
x = 3
Step-by-step explanation:
4 - 7x = 1 - 6x (Given)
4 - 1 - 7x = 1 - 1 - 6x (Subtraction Property of Equality)
3 - 7x = -6x (Simplify)
3 - 7x + 7x = -6x + 7x (Addition Property of Equality)
3 = x (Simplify)
x = 3 (Symmetric Property of Equality)
