Two non vertical lines have slopes m₁ and m₂ ​, respectively. The lines are parallel if "m₁ = m₂" and the "y-intercepts" are unequal; the lines are perpendicular if m₁ = 1/m₂.

The slope of a line is a measurement of its steepness and direction.

The slope of a line formula computes the "vertical change" to "horizontal change" ratio between two distinct points along a line.

Some key features regarding the slopes of the lines are-

1. Slope of Parallel Lines:

A set of parallel lines always has the same inclination angle. Assume we possess two parallel lines l1 and l2 in the reference plane, inclined at angles θ1  and θ2 with the x-axis, respectively, such that the, θ2 = θ1.

m1 = m2

Therefore, the slopes of the two given parallel lines are equal.

2. Slope of Perpendicular Lines:

A pair of perpendicular lines everytime form a 90 angle. Imagine we have two perpendicular lines l2 and l1 in the coordinate plane, inclined at angles θ1 and θ2 with the x-axis, respectively, so that the provided angles follow the external angle theorem, θ2 =  θ1 + 90.

m1 = tan θ1

m2 = tan (θ1 + 90º) = - cot θ1

m1 × m2 = -1

Therefore, the product of slopes of two given perpendicular lines is equal to -1.

x  = 0, x = 3

2

x = -3, x = 3

3

x = -2/3, x = 1

4

x = -1, x = 1, x = -3/2

Step-by-step explanation:

1

3x^2 - 9x = 0

3x(x - 3) = 0

when 3x = 0, x  = 0

when x - 3 = 0, x = 3

2

x^2 - 9 = 0

(x - 3)(x + 3)

when x + 3 = 0, x = -3

when x - 3 = 0, x = 3

3

3x^2 - x = 2

3x^2 - x - 2 = 0

(3x + 2)(x - 1 ) = 0

when 3x + 2 = 0, 3x = -2, x = -2/3

when x - 1 = 0, x = 1

4

2x(x^2 - 1) + 3(x^2 - 1) = 0

2x^3 - 2x + 3x^2 - 3 = 0

2x^3 + 3x^2 - 2x - 3 = 0

(x + 1)(x - 1)(2x + 3) = 0

when x + 1 = 0, x = -1

when x - 1 = 0, x = 1

when 2x + 2 = 0, 2x = -3, x = -3/2

Answer:

the answer is graph B

Step-by-step explanation:

The correct options for the linear combinations of the vectors are given by:

A, B, C, D, E and F.

The span between two vectors is the set that contains all linear combinations between these two vectors.

Supposing we have two vectors u1 and u2, as is the case in this problem, the infinitely many linear combinations have the following format:

k1u1 + k2u2

In which k1 and k2 are real numbers.

With k1 = 4 and k2 = -7, we get that option A is correct.

For option B, the vector 0 will always be a part of the span, as it can be formed with constants 0, hence it is correct.

The dimension of the span is of 3, as the vectors have 3 elements, hence option C is correct.

The underlying vectors will always also be part of the span, as they can be formed with their constant 1 and the others at 0, hence options D and F are correct.

The size of the span of any vectors is of infinity, hence option E is correct while option G is not.

Step-by-step explanation:

You are given  a.......0.........d

a= -1, b=0, c=1, d=10

The given equation is 2n = 2m + n and the proof is n = 2m

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

The equation is given as

2n = 2m + n

Subtract n from both sides of the equation

So, we have

-n + 2n = 2m + n - n

Evaluate the like terms

n = 2m

Hence, the given equation is 2n = 2m + n and the proof is n = 2m

Step-by-step explanation:

It should be noted that while Euclidean geometry wants to understand the geometry of flat, two-dimensional spaces, the non-Euclidean geometry studies curved, rather than flat, surfaces.

Euclidean geometry, often known as Euclid's geometry, is the study of geometry based on concepts like points, lines, and planes of flat spaces that are not yet defined. It is, in other words, the study of geometrical shapes, including solid and plane shapes, and how these shapes relate to one another in terms of lines, points, and surfaces.

Any geometry that is not the same as Euclidean geometry is considered non-Euclidean geometry. It should be noted that although Euclidean geometry is useful in many fields, in some cases, non-Euclidean geometry is vital as well.

Answer:1.125

Step-by-step explanation:

So the supermarket unit price for 24.0 ounce box is $0.2 and 15.3-ounce box is $0.3

Step-by-step explanation:

It is common that superstores often display units of their choice. That's okay. What you can do is perform some simple calculations to calculate the unit price in whatever unit you want.

For example, here the price for 15.3 ounce box is $4.62

So, the price for 1 box would be

15.3 x 1/15.3 = 4.62 x 1/15.3

1 box = $0.3 (Unit price)

Similarly,

24 = 5.35

24 x 1/24 = 5.23 x 1/24

1 box = $0.2 (Unit price)
