Answer:
Step-by-step explanation:
75$ times 0.80= 60$
75$-60$= 15$
Answer:
Line DC.
Step-by-step explanation:
Point D and Point C are not connected and, therefore, do not form a line.
Considering the vertex of the parabola, the correct statement is given by:
The range of the function is all real numbers less than or equal to 9.
<h3>What is the vertex of a quadratic equation?</h3>
A quadratic equation is modeled by:

The vertex is given by:

In which:
Considering the coefficient a, we have that:
- If a < 0, the vertex is a maximum point, which means that the range is all real numbers less than or equal to
.
- If a > 0, the vertex is a minimum point, which means that the range is all real numbers greater than or equal to
.
In this problem, we have that:
- a = -1 < 0, hence the vertex is a maximum point.
Hence the range is described by:
The range of the function is all real numbers less than or equal to 9.

When that equation is graphed, it produces a straiught line. The slope
of the line is 5, and the line intersects the y-axis at y=6.
