Answer:
I think that you may have forgotten to write out some of the question
Step-by-step explanation:
0-22.3 is not a full equation, the answer to that would be -22.3
0-2-3 is also not a full equation, the answer to that would be -5
as for 0-2=-3 that is not correct, 0-2 is -2

Option B 6x-7y = -11 is correct
Step-by-step explanation:
We need to write the equation of the given line in standard form.
The points are (1/2,2) and (3,1)
The equation used is:
where m is the slope.
Finding slope :
x₁= 1/2, y₁=2, x₂=-3, y₂=-1
Putting values:
Now taking point (1/2,2) and s;ope m = 6/7 finding equation:
So, Option B 6x-7y=-11 is correct

You need to use the quadratic formula for this question.
In your equation, a is 1, b is 6, and c is 4. (I couldn't find a plus minus sign, so that's what the +- means, sorry if there's confusion.)
Sub those into the quadratic formula, and
For the first answer, we should get
x1=-0.7639, when you add the √6^2-4(1)(4)
For the second answer, we get
x2=-5.2361 when we subtract the √6^2-4(1)(4)
Therefore, the x values that make this equation equal to 0 should be approximately -0.7639 and -5.2361.
The more specific answers are
x1= -3+√5 and x2=-3-√5.
Answer: Alternative optimal
Step-by-step explanation:
Alternative optimal solution means that
there are several optimal solutions that can be used to get identical objective function value.
Therefore, a scenario whereby the optimal objective function contour line coincides with one of the binding constraint lines on the boundary of the feasible region will lead to alternative optimal solution.
