Answer:
j = [tex]\frac{2k+3}{5}[/tex]
Step-by-step explanation:
Given
[tex]\frac{5j-3}{2}[/tex] = k ( multiply both sides by 2 to clear the fraction )
5j - 3 = 2k ( add 3 to both sides )
5j = 2k + 3 ( divide both sides by 5 )
j = [tex]\frac{2k+3}{5}[/tex]

Since he has 1 paper complete now and after 3 hours he would have 7 since 3x2=6 and 6+1=7
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.

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)

Plot the points ( 2 , 4 ) (2,4)left parenthesis, 2, comma, 4, right parenthesis and ( 2 , − 8 ) (2,−8)left parenthesis, 2, comma, minus, 8, right parenthesis on the coordinate plane below. What is the distance between these two points?
The distance between the points (2, 4) and (2, -8) on the coordinate plane is 12 units.
What is a coordinate plane?The two-dimensional geometric system of a coordinate plane, also called a Cartesian plane, is used to plot and find points using a pair of numerical coordinates.
The formula for calculating distance between two locations in a two-dimensional coordinate plane is as follows:
Distance = [tex]\sqrt((x_2 - x_1)^2 + (y_2 - y_1)^2)[/tex]
where [tex](x_1, y_1)\; and\; (x_2, y_2)[/tex] are the coordinates of the two points.
Using the given points:
Point 1: (2, 4) with [tex]x_1 = 2 \;and \;y_1 = 4[/tex]
Point 2: (2, -8) with [tex]x_2 = 2 \;and\; y_2 = -8[/tex]
Putting these values into the distance formula, we get:
Distance = [tex]\sqrt((2 - 2)^2 + (-8 - 4)^2)[/tex]
Simplifying further:
Distance = [tex]\sqrt(0^2 + (-12)^2)[/tex]
Distance = [tex]\sqrt(0 + 144)[/tex]
Distance = √144
Distance = 12
