Amount of points don't matter what is the question lets see if I can help
Answer:
Options 1,2,3 are correct statements
The first values in an ordered pair ( the coordinates) are the domain : ( -3,-2,-1,0,1)
The second values are the range : (-1,1,2,3,4,5)
One input should have only one output for a function.
But -1 input has 2 outputs: -1 and 3.
Thus, it is a relation and not a function.
Hope it helps :)

Answer:
E = 64.05
NG = 52.29
O = 35.15
Step-by-step explanation:
With the statement we can create a system of 3X3 equations that would be as follows:
E = electricity
NG = natural gas
O = oil
0.35 * E + 0.15 * NG + 0.25 * O = 25
0.35 * E + 0.15 * NG + 0.2 * O = 15
0.1 * E + 0.1 * NG + 0.1 * O = 20
If we pass this system equations to matrix and subtract it from the identity matrix we would have the following:
0.65 * E - 0.15 * NG - 0.25 * O = 25
-0.35 * E + 0.85 * NG - 0.2 * O = 15
-0.1 * E - 0.1 * NG + 0.9 * O = 20
Solving this system of equations around here can be very long and impractical, therefore, I attach a photo of the process:
And the answer is:
E = 64.05
NG = 52.29
O = 35.15
