Answer: B and E are irrational numbers
Given:
The equation is:

To find:
The graph of the line that contains ordered pairs that are solutions of the given equation.
Solution:
We need to find the graph of the given equation.
We have,

At
, we get


So, the x-intercept of the given equation is at point (0,4).
At
, we get


So, the y-intercept of the given equation is at point (4,0).
From the given graphs it is clear that the line in option C has x-intercept at point (0,4) and y-intercept at point (4,0).
Therefore, the correct option is C.
Answer:
E + F = 2c^2 + 5c + 4
Step-by-step explanation:
E=6c^2-2c-1
F=-4c^2+7c+5
E+F= 6c^2 -2c -1 + -4c^2 + 7c + 5
E + F = 6c^2 - 4c^2 - 2c + 7c - 1 + 5
E + F = 2c^2 + 5c + 4
