Answer:
1) y > x² + 4x - 5, y > x + 5
2) Rational
Step-by-step explanation:
For a parabola, if the shade is inside the curve then the value of y will be greater or equal to:
For a line, if the shade is above it then the value of y will be greater or equal to:
Therefore, since parabola doesn't have solid curve (--- graph) then the inequality is ">"
Therefore, the inequality for parabola is y > x² + 4x - 5
For a line, it does not have solid graph so the inequality is ">"
Therefore, the inequality for line is y > x + 5

The graph of function describes the shape of rational function. It cannot be exponential as exponential only has one curve. It cannot be logarithm for same reason as exponential. It cannot be polynomial as polynomial is continuous function but the graph is discontinuous at specific point x = 0.
That being said, all choices except rational are all continuous function by default but rational function isn't and since the graph is discontinuous then we can say that it's rational function.
Answer:
<h2>(0.5, 0.5)</h2>
Step-by-step explanation:
The formula of a midpoint of a segment AB with endpoints at A(x₁, y₁) and B(x₂, y₂):
From the graph we have the points A(-2, 4) and C(3, -3).

In the first four months of the year, Noralie's jewelry sales were declining. After April, her sales began to improve. The function below represents her monthly sales. Which graph represents the Noralie's sales?
Answer:
<h2>a = 3</h2>
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
From the question the slope is - 3
To find the value of a we have
Divide both sides by - 3
We have the final answer as
<h3>a = 3</h3>
