There is no choice on your list that must represent an odd integer.
If 'z' is an even integer, then (z-1) and (z+1) must both be odd integers.
Answer:
Step-by-step explanation:
I think it could be D
Sorry if not correct
Solve first for the solution of the inequalities. This can be done by replacing first the inequalities sign with the equal sign.
x + y = 1
2y = x - 4
The values of x and y from the system of linear equation are 2 and -1. This means that the intersection of the lines should be at point (2, -1).
Substitute 3 to x and determine the value of y from the second inequality.
2y ≥ x - 4
Substituting,
2y ≥ 3 - 4, y ≥ -1/2
Hence, the solution to this item should be the fourth one.

Answer:
y = -3x - 5
Step-by-step explanation:
The equation of a line is given as either:
where m is the slope, and b is the y-intercept.
or
where given that you have a point (x, y), y₁ is the y-value of the point, m is the slope, and x₁ is the x-value of the point.
We can just plug in the point (0, -5) into the second equation and -3 for the slope.
<em>However,</em> (0, -5) tells us that this point must be a <u>y-intercept</u>, since the x-value of that point is 0. So, we can also just plug into the first equation -5 for the y-intercept and -3 for the slope.
So, we get:
y = -3x + (-5)
Which simplifies into:
y = -3x - 5
