For this context, we examine the function:
presented as:
The definition of the discriminant in a quadratic equation is provided by:
Sentences correspond to the types of roots: Different real roots, equal real roots, or distinct complex roots
Upon substituting the provided values, we arrive at
This indicates that there are two equal real roots.
To discover the intersections along the x-axis, we apply the quadratic formula:
Plugging in the values yields: 
The intersection on the x-axis is
Respuesta: 1.8 bolsas
Explicación paso a paso:
A partir de la pregunta, considerando que Robby tiene 4 4/9 bolsas de comida para mascotas, 2/5 eran comida para perros.
2/5 de 4 4/9 = comida para perros.
Convierte 4 4/9 a fracción impropia= 40/9.
2/5 de 40/9 implica 2/5 × 40/9.
= 16/9.
= 1.78 o 1.8.

The correct answer is "Option B." There seems to be an error with the options provided; however, the appropriate choice is detailed in the attached file. If the column of the matrix and the span of A are both equal to R^5, then A must have a pivot in each row, hence resulting in five pivot columns that confirm choice B as accurate.
You can determine your result by adding +7 to every value.
Option C: The paths of the skaters intersect at two points, but only one of them falls within the rink's boundaries. Step-by-step explanation: The center of the ice rink is established at coordinates (0,0) with a radius of 35 meters. The standard equation for a circle, given the coordinates (a,b) and radius r, is (x - a)² + (y - b)² = r². Therefore, the skating area can be defined as x² + y² = 35². Susan's skating path follows the equation y = 6x - x² - 5, meanwhile, Luke maneuvers from point (10, –21) along a parabolic path centered at (8, –9). This leads us to solve for the intersection points of their paths, confirming that while they intersect twice, only one point exists within the rink's confines.
