Answer:
B) 
Step-by-step explanation:
To find the function which has vertex at the origin.
Solution:
For a function to have its vertex at origin the function must pass through point (0,0) which means 
.
We will find 
for each of the given functions and check if it has vertex at origin.
To find we will plugin 
in the function.
A) 
Vertex is not at the origin.
B)
[Any number times zero is = zero]
Vertex is at the origin.
C) 
Vertex is not at the origin.
D) 
Vertex is not at the origin.
Answer:
C
Step-by-step explanation:
The first term -2 is also -B; therefore A and B can be eliminated.
-1+3 is 2, and -4 is the only term used in the formula, so D is also eliminated
Answer:
-8y = 6
Step-by-step explanation:
-6x+4y = -8
6x -12y = 14
Add the equations
-6x+4y = -8
6x -12y = 14
--------------------
0x -8y = 6
The correct answer is
135 + 89 + c ≥ 325; c ≥ 101
