Answer:
Each has 30 edges and 20 equilateral triangle faces with five meeting at each of its twelve vertices. Both have icosahedral symmetry. LET ME KNOW IF HELPED
Substitute each value of x, calculate, and if the answer equals to the given value of y, then the point does lie on y = 2x
Point A (1, -1)
y = 2(1)
y = 1
The answer is not y = -1 as given in the question, hence point A does not lie on y = 2x
-----------------------------------------------------------------------------------------------------------
Point B (1, 3)
y = 2(1)
y = 2
The answer is not y = 3 as required, hence point B does not lie on y = 2x
---------------------------------------------------------------------------------------------------------------
Point C(-2, -4)
y = 2(-2)
y = -4
The answer is y = -4 as required. Hence, point C does lie on y = 2x
-----------------------------------------------------------------------------------------------------------------
Point D(-2, 4)
y = 2(-2)
y = -4
The answer is not y = 4 as required, so point D does not lie on y = 2x.

Correct Answer: C
1/3 if you have a positive and a negative, it will turn into a positive so 11/12-7/12
Answer:
5x - 2y = -2
Step-by-step explanation:
-2x - (-7x) = -2x + 7x = 5x
y - 3y = -2y
0 - 2 = -2
Answer:
-8 +12i
Step-by-step explanation:
(1 + 9i)-(9 - 3i)
Distribute the minus sign
(1 + 9i)-9 + 3i
Combine like terms
1-9 +9i +3i
-8 +12i
