1) write a system on equations with the solution (2, -3). Work the problem out using the substitution method
solmaris [256]

The system of the equations that have the solution of (2, -3) are given below.

3x + 2y = 0 and 3y = 2x - 13

<h3>What is the linear system?</h3>

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

Write a system of equations with the solution (2, -3).

From a single point, an infinite number of lines pass through this point.

Let one line is passing through the origin. Then the equation of the line will be

\rm y  = \dfrac{-3}{2} (x)\\\\y = -1.5x

And the other line is perpendicular to the line which is passing through the origin and a point (2, -3).

\rm y = \dfrac{2}{3} x + c

Then this line also passes through a point (2, -3). Then the value of c will be

\rm -3 = \dfrac{2}{3} \times 2 + c\\\\c \ \  = -13

Then the equation of the line will be

3y = 2x -13

More about the linear system link is given below.

Find the area of a parallelogram whose base is 12cm and altitude is 8cm. Also find the other base of its corresponding altitude
lukranit [14]

Answer:

Step-by-step explanation:

Area of parallelogram = base * height

                                    = 12 * 8

                                    = 96 cm²

Area of parallelogram = 96

base * height = 96

          base = 96/height

          base = 96/16

         base = 6 cm

Please help me with this math problem urgent
Luba_88 [7]

Answer:

11/5

Step-by-step explanation:

We can find the slope by

m = (y2-y1)/(x2-x1)

   = (5 - -6)/(-4 - -9)

   = (5+6)/(-4+9)

    = 11/5
