Answer:

Linear equations are a combination of constants and variables. The standard form of a linear equation in one variable is represented as ax + b = 0 where, a ≠ 0 and x is the variable. ax + by + c = 0, where, a ≠ 0, b ≠ 0 , x and y are the variables.

Answer:

The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line. An example of linear equation is y=mx + b.

A triangle has angle measures that are related as follows: -the largest angle is eight times the smallest angle -the middle angl
andriy [413]

Answer:

The angles are 15 degrees, 45 degrees and 120 degrees

Step-by-step explanation:

The triangle has three three sides and three angles. The sum of the angles in a triangle is 180 degrees

Let x = the size of the largest angle of the triangle

Let y = the size of the middle angle of the triangle

Let z = the size of the smallest angle of the triangle.

x + y + z = 180 - - - - -- - - - - - - 1

The size of the largest angle is eight times the size of the smallest angle.

This means

x = 8z

The size of the middle angle is triple the size of the smallest angle. This means

y = 3z

Put x = 8z and y = 3z in equation 1

8z + 3z + z= 180

12z = 180

z = 180/12 = 15

x = 8z = 8×15 = 120

y = 3z = 3 × 15 = 45

Which conic section does the equation below describe? <br> x^2+y^2+2x-8y-13=0
Gre4nikov [31]

Answer:  B) Circle

<u>Step-by-step explanation:</u>

First, complete the square:

x² + 2x + <u>  1   </u>  + y² - 8y + <u>  16  </u> = 13 + <u>  1  </u> + <u>  16  </u>

       ↓       ↑             ↓         ↑

   (2/2) = (1)²          (-8/2) = (-4)²

       (x + 1)²    +             (y - 4)²   =  30

The result is a circle whose center is (-1, 4) and radius is √30

What was Dimitri's mistake? He mixed up the coordinates of the ordered pair when Substituting it into the equations 7x+9y=-4 and
seropon [69]

Answer:

He made a mistake in his calculations when simplifying 5x - 2y

Step-by-step explanation:

Given

The coordinate pair

(x,y) = (2,-2)

The equations

7x + 9y = ?

5x - 2y = ?

Dimitri's Solution

Equation\ 1: 7x + 9y = -4.

7(2) + 9 (-2) = -4.

14 + (-18) = -4.

-4 = -4.

Equation\ 2: 5x -2y = 6.

5(2) - 2 (-2) = 6.

10 - 4 = 6.

6 = 6.

Required

Identify Dimitri’s mistake

In the first equation, Dimitri made no mistake.

However, he made a mistake when simplifying the second equation.

We have:

5x - 2y

and

(x,y) = (2,-2)

Substitute x = 2 and y = -2

So, we have:

5(2) -2(-2)

Open bracket

10 +4

Finally, we have:

14

Please solve, 1-8n-8= -7n-6n-12?​
Marta_Voda [28]

Answer:

n = -1

Step-by-step explanation:

1 - 8n - 8 = -7n - 6n - 12

Simplify

-8n - 7 = -13n - 12

Add 7 to both sides

-8n = -13n - 5

Add 13n to both sides

5n = -5

Divide both sides by 5

n = -1
