The coordinates of the line are (-7,8) and (2,-3), what is the slope of the line

Answer:  Create equations. Top length=Bottom length

Left side = right side.

Combine like terms and rewrite the equations.  

Use the new equations to create a system of equations to solve for x and y.

Once you have x and y, you can substitute those in the expressions for the lengths of the parallelogram.

You should end up with top and bottom lengths of 10. The sides are 9.

Step-by-step explanation:

3x-5 = 18 -2y . Rewrite as 3x + 2y = 23

x+4 = 21 -3y    Rewrite as  x + 3y = 17

The system of equations is

3x + 2y = 23   and  x + 3y = 17 . To solve by substitution, multiply the second equation by -3   It becomes  -3x-9y= -51  Add the equations so the x terms cancel. Solve for y

3x + 2y = 23

-3x - 9y = -51

0  -7y  = - 28  Divide both sides by -7.   y = 4

Substitute 4 for y,  solve for x

x + 3(4) = 17

x + 12 = 17 . Subtract 12 from both sides   x = 5

Substitute the values of x and y in the expressions

Top: 3x-5    is 3(5) -5  becomes 10

Bottom: 18 -2y  is  18 - 2(4) becomes 10

Left:  x +4   is (5) + 4  becomes 9

Right:  21 - 3y  is  12 -3(4)  becomes 9

Answer:

The equation which best describes the graph of a line that has a slope of - 1/2 and passes through the point (2,-3) will be:

Step-by-step explanation:

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

In our case, we are given

The slope m = -1/2

Point (2, -3)

now substituting m = -1/2 and (2, -3) in the slope-intercept form of the line equation to determine the y-intercept

[tex]y = mx+b[/tex]

-3 = -1/2(2) + b

-3 = -1 + b

b = -3 + 1

b = -2

now substituting m = -1/2 and b = -2 in the slope-intercept form of the line equation

y = mx + b

y = -1/2x + (-2)

y = -1/2x - 2

Therefore, the equation which best describes the graph of a line that has a slope of - 1/2 and passes through the point (2,-3) will be:

Answer:

the answer for this problem would be 24 dollars.

Answer:

1 * -2, 7 - 9, and 2^2 - 2 * 3

Answer:

21

Step-by-step explanation:

6(y^2) - 24y -51 = 6 4 - 24y - 51

(6 4) - (24y) - 51 = 24 - -48 - 51

(24 - -48) - 51 = 72 - 51

72 - 51 = 21

Answer:

4

Step-by-step explanation:

We are asked to find a slope whilst given a graph.

To solve for slope, we must pick two coordinate points that are not decimals and following the formula of rise over run, which in basic terms y over x.

So based on what I see, I can see (1, 1) and (2, 5).

The rise over run is as followed :

[tex]\frac{y2 - y1}{x2 - x1}[/tex]

2 and 1 meaning the first and second number within the coordinate, so substitute :

[tex]\frac{5 - 1}{2 - 1}[/tex]

[tex]\frac{4}{1}[/tex]

Divide :

[tex]4[/tex]

4 is our slope.

Answer:

x = 9

Step-by-step explanation:

3.1= -5.9+x

x - 5.9 = 3.1

x - 5.9 + 5.9 = 3.1 + 5.9

x = 9

Answer:

x = - 10

Step-by-step explanation:

Given

10 - x = - 2x ( add 2x to both sides )

10 + x = 0 ( subtract 10 from both sides )

x = - 10

Answer:

30° and 110°

55° and 85°

70°and 70°

Step-by-step explanation:

Given that :

Angle B = 40°

Sum of angles in a triangle :

Angle (A + B + C) = 180°

A + 40 + B = 180

A + C = 180 - 40

A + C = 140°

From the Given options ;

The sun of the Angles Given must add up to 140°

Hence,

30° and 110° = 140°

55° and 85° = 140°

70°and 70° = 140

Answer:

9/2

Step-by-step explanation:

3/4 x 6 can be thought of as multiplying 3/4 x 6/1

When multiplying fractions, multiply the numerator (top number) with the numerator, and the denominator with the denominator.

3/4 x 6/1 = (3x6)/(4x1)

3/4 x 6/1 = (18)/(4)

3/4 x 6/1 = 9/2
