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

NEED HELP ASAP. A garden in the shape of an equilateral triangle measures 6 feet on each side. An irrigation hose runs from one
Step2247 [10]

Answer:

Find the length of the hose = 5.2 feet

Step-by-step explanation:

The garden is divided into two similar triangle.

The hose divided one side of the triangle to two equal parts.

Side a = 6ft

Side b = 3ft

Side c = ? (length of hose)

a² = b² + c²

6² = 3² + c²

36 = 9 + c²

27 = c²

√27 = c

5.196 = c
