Answer:
The answer is D.
Step-by-step explanation:
As said in the problem, we are labeling the total minutes used <em>x </em>and the total monthly income as <em>y</em>. This means that in the graph we will be making the y-axis should represent the total monthly charges, and the x-axis should represent the total minutes.
Thus the graph should go through points (100,155) and (200,245) and its slope is:

The rhombus is shown in the diagram below
The length of one side of the rhombus is 5 units, hence all the other sides are also 5 units each.
Well, first do height times width times depth, so 2 times six times eleven. so what's 12 times eleven? 132. Now multiply 132 times two and get 264. Your answer is 264.
4x-3 ≥ 5
4x ≥ 5+3 (add 3 to both sides)
x ≥ 8/4 (divide both sides by 4)
x ≥ 2
a is the answer.

3x-5 ≥ 7
3x ≥ 7+5
x ≥ 12/3
x ≥ 4
b is the answer
so, did you understand?
For this all you have to do is plug in the x and y values into the equation and see if it is a true statement. If it's true then it's on the line. The x value is 2 and the y is -4.
12x + 3y = 6
12 (2) + 3 (-4) = 6
24 -12 = 6
12 = 6
The statement 12=6 is not a true statement so that point is not on the line.
