What is the center of MN given M(3, -1) and N(7,-5)

Mathematics
1 answer:
Neko [114]2 years ago
3 0

Answer:

(5, -3)

Step-by-step explanation:

So the center of the two points, or a line can be defined using the equation: midpoint=(\frac{x_2+x_1}{2}, \frac{y_2+y_1}{2}). So using the two points you gave, you simply plug the values in to get

midpoint=(\frac{3+7}{2}, \frac{-1+(-5)}{2})\\

Add numerators:

midpoint=(\frac{10}{2}, \frac{-6}{2})

Simplify fraction:

midpoint=(5, -3)

The inequalities are matched with their correct graph respectively as follows:

  1. D ⇒ {(x, y): y > x²}.
  2. G ⇒ {(x, y): y ≥ x²+ 3
  3. C ⇒ {(x, y): y ≤ 3x² + 2}
  4. A ⇒ {(x, y): y ≥ 2x² - 5x + 1}
  5. J ⇒ x²- 3x ≥ 0
  6. H ⇒ x² - 3x + 2 ≤ 0
  7. B ⇒ {(x, y): y ≤ 1 - x²}
  8. B ⇒ {(x, y): y ≥ -1}

<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.

<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 arguments:

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

In Geometry, if the leading coefficient of a quadratic equation is greater than (>) zero, the parabolic curve would open upward while the parabolic curve would open downward when the leading coefficient of a quadratic equation is less than (<) zero.
