The correct options for the linear combinations of the vectors are given by:
A, B, C, D, E and F.
What is a span between two vectors?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.

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

the supermarket displays the unit price for the 24.0-ounce box in terms of cost per ounce, but displays the unit price for the 24-ounce box in terms of cost per pound. what are the unit prices, to the nearest cent, given by the supermarket? unit price for the 15.3-ounce box
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)

Find the degree of the term.
Answer:
Here,
-2xy³
The exponent of x = 1
The exponent of y = 3
Thus, the degree of the term = 1+3 = 4
Step-by-step explanation:
Given the term
-2xy³
We know that the degree of the term involving xy expression cab be calculated by adding the exponents of x and y.
In other words, the degree of a term in two variables would be the sum of the exponents of the variables in the termHere,
-2xy³
The exponent of x = 1
The exponent of y = 3
Thus, the degree of the term = 1+3 = 4
Kathy studies three times as long as Sally. The girls studied a total of 48 hours. What is equation?
The equation is,
x + 3x = 48
or, 4x = 48
What is an expression?
Mathematical expression is defined as the collection of the numbers and variables and functions by using operations addition, subtraction, multiplication, and division.
Let study time of Sally = x hour
Hence, Study time of Kathy = 3x hour
Since, Total studied time of girls = 48
Hence, The equation is;
x + 3x = 48
4x = 48
So, The equation is,

two nonvertical lines have slopes m 1m 1 and m 2m 2 , respectively. the lines are parallel if and the are unequal; the lines are perpendicular if
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.
What is slope of a line?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.

b. What is the main difference between this geometry and the others that have been discussed in this activity? Explain.
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.
What is the difference?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.
