She was given 12 quarters. When she had 6x as many quarters in her bank, she had 24 quarters in it. When she had 9x as many, she had 36 quarters in it. 36-24 is 12.
Answer:
44 times
Step-by-step explanation:
There is a 50% (2/4) chance that this could occur, as given in the question.
88*.5 = 44.
Let x and y be the dimension of the rectangle. Suppose x is the width and y is the length. Since the perimeter is 36, we have
If we increase the length by 1, we change . Similarly, if the width is increased by 2, we change . So, the increased area is
If we substitute the value for y deduced in the first equation, we have
The solutions to this equation are
One of them is negative, so we have to choose the positive one:
Which implies
The inequalities and the points are
- y + 4x < 8: (0, 6) and (-2, 5)
- y - 3 ≥ 1/2x: (0, 6) and (-2, 5)
<h3>How to graph the
system of inequalities?</h3>
The system of inequalities is given as:
y + 4x < 8
y - 3 ≥ 1/2x
Next, we plot each inequality in the system of inequalities using a graphing calculator
See attachment for the graph of the system of inequalities y + 4x < 8 and y - 3 ≥ 1/2x
From the attached graph, we have the following points:
y + 4x < 8: (0, 6) and (-2, 5)
y - 3 ≥ 1/2x: (0, 6) and (-2, 5)
