A line has a slope of 3 and goes through the point (6,-5). What is the equation of this line in Standard Form?
- 3x +y= 21
-3x +y= -23
- 3x +y = -13
3x +y = 13
​

Answers

Answer:

−3x+y=−23

Step-by-step explanation:

wow this is exactly 1 year ago from today

 -3x +y= -23  is the equation of this line in Standard Form .

What is in slope-intercept form?

Y = mx + b, which defines a line, is an equation's slope-intercept form. When a line is graphed, its slope, m, and its point of intersection with the y-axis, b, also known as the y-intercept, are shown. To find answers for x, y, m, and b, utilize slope intercept form.

m = 3

the point =  (6,-5)

the equation of this line

           y - y₁ = m ( x - x₁)

           y - ( -5 ) = 3 ( x - 6 )

           y + 5 = 3( x - 6 )

            y + 5 = 3x - 18

             y = 3x - 18 - 5

             y = 3x - 23

            -3x +y= -23

Does anyone know how to solve 3 by 3 linear systems?

In the system below, use equation (1) with equation (2) to eliminate x. Then use equation (1) with equation (3) to eliminate x.

x-y-2z=4 (1)

-x+3y-z=8 (2)

-2x-y-4z=-1 (3)

Answers

Answer:

x = 3, y = 3, z = - 2

Step-by-step explanation:

Given the 3 equations

x - y - 2z = 4 → (1)

- x + 3y - z = 8 → (2)

- 2x - y - 4z = - 1 → (3)

Add (1) and (2) term by term to eliminate x

2y - 3z = 12 → (4)

Multiply (1) by 2 and add to (3) to eliminate x

2x - 2y - 4z = 8 → (5)

Add (3) and (5) term by term to eliminate x

- 3y - 8z = 7 → (6)

Multiply (4) by 3 and (6) by 2

6y - 9z = 36 → (7)

- 6y - 16z = 14 → (8)

Add (7) and (8) term by term to eliminate y

- 25z = 50 ( divide both sides by - 25 )

z = - 2

Substitute z = - 2 into (7)

6y + 18 = 36 ( subtract 18 from both sides )

6y = 18 ( divide both sides by 6 )

y = 3

Substitute y = 3 and z = - 2 into (1)

x - 3 + 4 = 4

x + 1 = 4 ( subtract 1 from both sides )

x = 3

Solution is x = 3, y = 3, z = - 2

The greater of two consecutive even integers is at most fifty less than five times the smaller. Which of these represents the inequality needed to solve for the smaller integer, x, as well as its solution?

12x = 20 + 4y          Subtract 20

Answers

Answer:

Step-by-step explanation:

We are to choose all the equation that evaluates b to be 11. The following equations are true;

77 = 7b

To get b, we will divide both sides by 7

77/7 = 7b/7

11 = b

b = 11

This shows that the equation is correct since b = 11

Also 9 = b-2

To get b, we will add 2 to both sides of the expression

9+2 = b-2+2

11 = b

b = 11

This shows that the equation is correct since b = 11

Hence option C and D are correct

A car travels a distance of 1280 metres at an average speed of 64 kilometres per hour.
Ра:
Calculate the time it takes for the car travel this distance,
Give your answer in seconds​

Answers

Answer:

The answer is 20 hours

Step-by-step explanation:

This is becuase 1280 divided by 64 equals 20.  There are no unit coversions.

In time t = 0.02 hour the car travels a distance of 1280 meters with a speed of 64 kilometers per hour.

Given that,
A car travels a distance of 1280 meters at an average speed of 64 kilometers per hour.

What is speed?

Speed is defined as when an object is in motion, the distance covered by that object per unit of time is called speed.

Here,
Time  = distance/speed
Time. t = 1.280 / 64

t = 0.02 hours

Thus, In time t = 0.02 hour the car travels a distance of 1280 meters with a speed of 64 kilometers per hour.

Since both angles have the same measurement you set them equal to each other as so & solve for x

x+90=95

x=5

In order to find the angle measurements you plug in 5

2(5)+90

Supplementary angles add up to 180 degrees so the angle next to the 100 degree one is 80 degrees
