Answer:

B. x = 5 +i√5  and    x = 5 - i√5

Step-by-step explanation:

Because when two linear equations graph this very same line, a system of two linear simultaneous equations variables cannot be solved.

A linear equation seems to be an algebraic equation of something like the form y=mx+b, where m is the slope as well as b is the y-intercept, and only a constant and an initial-order (linear) component are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

2x+6y=-28       (i)

x + 3y = -14      (ii)

Subtract 3y from both sides of the equation(ii)

[tex]\begin{matrix}&x=-14-3y\\&2x+6y=-28\\\end{matrix}[/tex]

Replace all occurrences of x with -14-3y in each equation.

Replace all occurrences of x in 2x+6y=-28 with -14-3y.

[tex]\begin{matrix}&2(-14-3y)+6y=-28\\&x=-14-3y\\\end{matrix}[/tex]

Simplify the left side.

Simplify 2(-14-3y)+6y.

[tex]\begin{matrix}&\ -28=-28\\&x=-14-3y\\\end{matrix}[/tex]

Remove any equations from the system that are always true.

[tex]x=-14-3 y[/tex]

If LMNO is a parallelogram then NM=7=OL and the value of X is 7 unit

What is a Parallelogram?

A quadrilateral having two sets of parallel sides is referred to as a parallelogram. In a parallelogram, the opposing sides are of equal length, and the opposing angles are of equal size. Additionally, the interior angles that are additional to the transversal on the same side. 360 degrees is the sum of all interior angles.

A parallelepiped is a three-dimensional shape with parallelogram-shaped faces. The base (one of the parallel sides) and height (the distance from top to bottom) of the parallelogram determine its area. A parallelogram's perimeter is determined by the lengths of its four sides.

As it is a parallelogram so, the opposite sides of the parallelogram are equal so NM=OL and ON=LM ,

The coordinates of the point P that is 2/5 of the way from A to B are:

P = (-5.6, 11,2)

If we want to find a point that is 2/5 of the way between two points (x₁, y₁) and (x₂, y₂), then we need to use the formula:

( (3/5)x₁ + (2/5)x₂,  (3/5)y₁ + (2/5)y₂)

Here the two points are (-8, -2) and (6, 19), using the above formula we will get the point P:

P = ( (3/5)*-8 + (2/5)*-2,  (3/5)*6 + (2/5)*19)

P = (-5.6, 11,2)

The features of each function shown on Cartesian plane:

Function 1: Domain: 2 ≤ x < 3, Range: 1 < y ≤ 3, y = - 2 · x + 7

Function 2: Domain: - 4 ≤ x < 4, Range: - 4 ≤ y < - 2, y = (5 / 9) · x² - 2

In this question we must the determine the domain and the range of each of two functions. The set of elements for the domain corresponds to the horizontal axis of the Cartesian plane, represented by variable x, while the vertical axis corresponds to the vertical axis of that plane, represented by variable y.

Now we proceed to determine the domain and the range of each function:

Function 1

Domain: 2 ≤ x < 3, Range: 1 < y ≤ 3

The definition of the function is:

3 = 2 · m + b

2 = 2.5 · m + b

(m, b) = (- 2, 7)

y = - 2 · x + 7

Function 2

Domain: - 4 ≤ x < 4, Range: - 4 ≤ y < - 2

The definition of the function is:

y + 2 = C · x²

3 + 2 = C · 3²

5 = 9 · C

C = 5 / 9

y + 2 = (5 / 9) · x²

Step-by-step explanation:

If a Triangle ΔABC has a perimeter of 38 and AC≅DC as well as BD≅BA than the side DC can be measures as CD=38-AB-BC if AB and BC are given.

A triangle is a three-sided polygon, which has three vertices. The three sides are connected with each other end to end at a point, which forms the angles of the triangle. The sum of all three angles of the triangle is equal to 180 degrees.

In the case of a triangle, the perimeter will be the sum of all the three sides. If a triangle has three sides a, b and c, then, Perimeter, P = a + b +c

As the perimeter of a triangle ABC is

Perimeter=AB+BC+CA

And we are given with only the perimeter of triangle;

Answer:

l =  10 feet

m = 30 feet

n = 25 feet

Total Perimeter = 65 feet

Step-by-step explanation:

The perimeter of a trianlge is the sum of its three sides, and in this case is equal to 65 feet.

65 feet = l + m + n

l + m + n = 65

We also know that:

 l = (1/3)m, and

n = l+m-15

Substitute these definitions of l and n into the original equation:

l + m + n = 65

[(1/3)m] + m + [l+m-15] = 65

[(1/3)m] + m + [[(1/3)m]+m-15] = 65

Simplify:

(1/3)m + m + (1/3)m + m - 15 = 65

2m + (2/3)m = 80

(6/3)m + (2/3)m = 80

(8/3)m = 80

m = 80*(3/8)

m = (10)*(3)

m = 30 feet

Since l = (1/3)m, l = 10 feet

Since n = l+m-15, n = 10 + 30 - 15, or 25 feet

The three sides are

      l:    10 feet

     m:  30 feet

     n:   25 feet

Total = 65 feet

Answer:

n = p+3q

Step-by-step explanation:

2^p x 8^q = 2^n

Exponent rules

Rewriting 8 as 2^3

2^p x 2^3^q = 2^n

Using the rule a^b^c = a^(b*c)

2^p x 2^3q = 2^n

Using the rule a^b * a^c = a^(b+c)

2 ^(p+3q) = 2^n

Since the bases are the same, the exponents are the same

p+3q = n

Answer:

[tex] \sf \: p + 3q = n[/tex]

Step-by-step explanation:

[tex]2^p*8^q=2^n[/tex]

First, write 8^q as a power of 2.

[tex]2^p*8^q=2^n\\2^p*2^3^q=2^n[/tex]

As all the bases are same, exponents are also equal.

Now add the powers.

Here,

One line passes through (0, 8) and (-1, 7)

Slope of the line = [tex]\frac{7-8}{-1-0}[/tex] = 1

Equation of line

y - 8 = 1(x - 0)

y - 8 = x

x - y = -8

Other line passes through (-4, 4) and (-3, 1)

Slope of the line = [tex]\frac{1-4}{-3-(-4)}[/tex] = -3

Equation of line

y - 4 = -3(x - (-4))

y - 4  = -3x - 12

3x + y = 4 - 12

3x + y = -8
