A system of inequalities is shown.

Mathematics

Doss [256]2 years ago

The system of inequalities which is represented in the graph shown (see attachment) is:

  1. y ≥ x² -2x -3
  2. y ≤ x +3

<h3>What is an inequality?</h3>

An inequality can be defined as a mathematical relation that compares two (2) or more integers and variables in an equation based on any of the following:

  • Less than (<).
  • Greater than (>).
  • Less than or equal to (≤).
  • Greater than or equal to (≥).

<h3>What is a graph?</h3>

A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.

By critically observing the graph which models the system of inequalities shown, we can infer and logically deduce the following points:

  • Both boundary lines on the cartesian coordinate are solid. Thus, the inequalities will both have the "equal to" sign.
  • The shading occurred above the quadratic boundary line. Thus, the inequalities below the linear boundary line is given by y ≥ x² + and y ≤ x +

In conclusion, we can infer and logically deduce that the system of inequalities which is represented in the graph shown (see attachment) is:

  1. y ≥ x² -2x -3
  2. y ≤ x +3

Answer:

The answer to your question is the last option

Step-by-step explanation:

Quadratic equation

                                2 = - x + x² - 4

Order the equation from the highest power to the lowest power. Do not consider 2 because it is not consider in the options given.

                               x² - x - 4  = 0

Identify a, b and c

                              (1) x² -(1) x - 4 = 0

    a = 1    b = -1    c = - 6      

Substitution              

                              \frac{-(-1) +- \sqrt{(-1)^{2} - 4(1)((-4)}}{2(1)}

1. Devin is making a candle by pouring melted wax into a mold in the shape of a square pyramid. Each side of the base of the pyr
Cloud [144]

Answer:

Devin will need 9 cubes of wax.

Step-by-step explanation:

To find the volume of the pyramid, you use (area of the base)* height of the pyramid divided by 3. You know the volume of a cube of wax is 32 cm^3. The volume of your pyramid is 270 cm^3. 270/32=8.4375.

Once you get 8.4375 cubes, you round to the next whole number, which is nine.
