Answer:q=-6

Step-by-step explanation:

If the solution of the system is  {(x,y) : x-3y=4}, then both equation should have proportional coefficients:

[tex]1/2=-3/q=4/8[/tex]

Solve it:

1/2 = -3/q

q=-3*2

q=-6

Check whether q=-6 is correct answer, substituting this value into the first ratio:

[tex]1/2=-3/-6=4/8[/tex]

q=-6

Problem 1

----------------

Work Shown:

The two points are [tex](x_1,y_1) = (1,-2)[/tex]  and [tex](x_2,y_2) = (4,4)[/tex]

Apply the distance formula to get the following

[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(1-4)^2 + (-2-4)^2}\\\\d = \sqrt{(-3)^2 + (-6)^2}\\\\d = \sqrt{9 + 36}\\\\d = \sqrt{45}\\\\d \approx 6.7082039\\\\d \approx 6.7\\\\[/tex]

The distance between the two endpoints is roughly 6.7 units. This is the same as saying the segment is roughly 6.7 units long.

======================================================

Problem 2

----------------

Work Shown:

We'll use the distance formula here as well.

This time we have the two points [tex](x_1,y_1) = (3,1)[/tex] and [tex](x_2,y_2) = (5,-2)[/tex]

The distance between them is...

[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(3-5)^2 + (1-(-2))^2}\\\\d = \sqrt{(3-5)^2 + (1+2)^2}\\\\d = \sqrt{(-2)^2 + (3)^2}\\\\d = \sqrt{4 + 9}\\\\d = \sqrt{13}\\\\d \approx 3.6055513\\\\d \approx 3.6\\\\[/tex]

This distance is approximate.

Answer:

840 minutes

Step-by-step explanation:

We solve this question using the LCM Method

Find and list multiples of each number of minutes which is given in the quest as 140, 210 and 280 minutes until the first common multiple is found. This is the lowest common multiple.

Multiples of 140:

140, 280, 420, 560, 700, 840, 980, 1120

Multiples of 210:

210, 420, 630, 840, 1050, 1260

Multiples of 280:

280, 560, 840, 1120, 1400

Therefore,

LCM(140, 210, 280) = 840

Therefore, they would have to wait after their first break together to get together again after 840 minutes

4.121216129m

Step-by-step explanation:

use sohcahtoa

tan(70) x 1.5m = 4.121216129m

The height of the tree is 4.12 m.

Given,

I put a ladder 1.5m away from a tree.

The ladder is inclined at 70 degrees about the horizontal.

We need to find out what is the height of the tree.

It is given by:

Tan Ф = Perpendicular / Base

Draw a figure of the given statement.

                       /   | A

                  /        |

(ladder) /             | (tree)

         /.                |

     /.                    |

C /_70°_______ | B  

<--------1.5m-------->              

Find the AB.

AB = height of the tree.

TanФ = AB / CB

Tan 70° = AB / 1.5m

2.7474 = AB / 1.5m

AB = 2.7474 x 1.5m

AB = 4.12 m

Thus the height of the tree is 4.12 m.

Answer:

m∠K = 43°

Step-by-step explanation:

By the properties of a parallelogram,

1). Opposite sides of a parallelogram are equal and parallel.

   (6y - 13) = 32 - 3y

   6y + 3y = 32 - 13

   9y = 45

   y = 5

2). Consecutive interior angles are supplementary.

   m∠M + m∠J = 180°

   (6x + 17) + (2x + 3) = 180°

   8x + 20 = 180°

    8x = 160°

    x = 20

    m∠M = (2x + 3)°

              = 2(20) + 3

              = 43°

3). Opposite angles of a parallelogram are equal in measure.

   m∠M = m∠K = 43°

Parallelogram is a closed shaped quadrilateral in which the opposite sides are equal and parallel. Consecutive angles in a parallelogram are supplementary. The value of x is 20, the value of the y is 5 and value of the angle K is 43 degrees.

Length of the  line XL is 2y+23.

Length of the  line Ml  is 32-3y.

Length of the  line JK is 6y-13.

Parallelogram is a closed shaped quadrilateral in which the opposite sides are equal and parallel. Consecutive angles in a parallelogram are supplementary.

As the sum of the consecutive angles is equal to the 180 degrees (supplementary). Thus,

[tex]\angle J+\angle M=180\\ 6x+17+2x+3=180\\ 8x+20=180\\ x=\dfrac{180-20}{8}\\ x=20[/tex]

Thus the value of x is 20.

As the the opposite sides of the parallelogram are equal. Thus,

[tex]\begin{aligned}\\ ML&=JK\\ 32-3y&=6y-13\\ 6y+3y&=32+13\\ 9y&=45\\ y&=\dfrac{45}{9} \\ y&=5\\ \end[/tex]

Thus the value of the y is 5.

Opposite angle are equal thus,

[tex]\angle K=\angle M\\ \angle K=2x+3\\ \angle K=2\times20+3\\ \angle K=43[/tex]

Thus the value of x is 20, the value of the y is 5 and value of the angle K is 43 degrees.

Answer:

first, third, and fourth

Step-by-step explanation:

Answer:

no solutions

Step-by-step explanation:

plug in y to x:

15x + 5(8 - 3x) = 20

15x + 40 - 15x = 20 ( you would subtract 15x from 15x.)

0 + 40 = 20

40 = 20

40 does not equal 20 so it would be no solutions.

Using substitution, the system above has no solutions.

Given  that,

Based on the above information, the calculation is as follows:

  Here we put the y value

15x + 5(8 - 3x) = 20

15x + 40 - 15x = 20  

0 + 40 = 20

40 = 20

Since 40 does not equal 20 so it would be no solutions.
