What is the solution for the system of linear equations shown in the graph?
answers are in the second image
Step-by-step explanation: The solution to this system of equations will be where the two lines on the graph intersect with each other.
Notice that both of them intersect to the left of the y-axis which means our x - coordinate must be negative.
They also intersect above the x-axis so our y-coordinate must be positive.
So the only option with a negative x-coordinate
and a positive y-coordinate is (-1/4, 3/4).

5x -2y = 88
3x+4y=58
Answer:
x=18
Step-by-step explanation:
add 2y to both sides 5x=2y+88
subtract 88 from both sides 2y=5x-88
substitute 2y in the second equation for 5x-88
3x+10x-176=58
add like terms 13x-176=58
add 176 both sides
13x=234
x=18
Answer:
( 18, -6.5 )
Step-by-step explanation:
First choose which method you plan on using: Substitution or Elimation. I chose elimination based off preference.
How to solve using Elimination:
5x -2y = 88 (multiply every number in this equation by two)
3x+4y=58
10x -4y = 176
3x+4y=58 (combine these two equations)
13x = 234 (isolate x by dividing by 13 on both sides)
x = 18 (this is your value for x)
3(18) +4y=58 (plug in for x)
54+4y=28 (solve)
4y = -26 (subtract 54 from both sides)
y = -6.5 (this is y)
write answer in (x, y) format
( 18, -6.5 )

7) What does a multiplier of \( 1.2 \) mean?
A multiplier of 1.2 means the value is multiplied or increased by a factor of 1.2.
A multiplier is a term used to represent a factor by which a value is multiplied or increased. It is a numeric value that indicates the extent of the increase or expansion of a given quantity. Multiplication by a multiplier results in scaling or changing the magnitude of the original value.
A multiplier of 1.2 indicates that a value will be increased by 20% or multiplied by a factor of 1.2. This means that when the multiplier is applied to the original value, the resulting value will be 1.2 times the original.

Use the Chain Rule to find dz/dt. (Enter youranswer only in terms of t.)
z =tan-1(y/x), x =et, y = 5- e-t
dz/dt =
By using chain rule dz\dt is \((-5e^t + e^{-t} + 5et) / (e^{2t} + 25 - 10e^{-t} + e^{-2t})\)
How to use the Chain Rule to find dz/dt?To use the Chain Rule to find dz/dt, we first need to find the partial derivatives of z with respect to x and y:
\(\partial z/ \partial x = 1 / (1 + (y/x)^2) * (-y/x^2) = -y / (x^2 + y^2)\)
\(\partial z/ \partial y = 1 / (1 + (y/x)^2) * (1/x) = x / (x^2 + y^2)\)
Then we can use the Chain Rule to find dz/dt:
dz/dt = ∂z/∂x * dx/dt + ∂z/∂y * dy/dt
Substituting the given expressions for x and y, we get:
\(dz/dt = (-y / (x^2 + y^2)) * (e^t) + (x / (x^2 + y^2)) * (5e^{-t})\)
Substituting back x = et and \(y = 5 - e^-t\), we get:
\(dz/dt = (-y / (x^2 + y^2)) * (e^t) + (x / (x^2 + y^2)) * (5e^{-t})\)
\(= (- (5 - e^{-t}) / (e^{2t} + (5 - e^{-t})^2)) * (e^t) + (et / (e^{2t} + (5 - e^{-t})^2)) * (5e^{-t})\)
\(= (- (5e^t - 1) / (e^{2t} + 25 - 10e^{-t} + e^{-2t})) + (5et / (e^{2t} + 25 - 10e^{-t} + e^{-2t}))\)
= \((-5e^t + e^{-t}) / (e^{2t} + 25 - 10e^{-t} + e^{-2t}) + (5et / (e^{2t} + 25 - 10e^{-t} + e^{-2t}))\)
Therefore, \(dz/dt = (-5e^t + e^{-t} + 5et) / (e^{2t} + 25 - 10e^{-t} + e^{-2t})\)

This is a stratified random sample. The student council took a stratified random sample of 100 students, with 25 students chosen from each of the four strata based on their class standing: freshmen, sophomores, juniors, and seniors.
This sampling method ensures that each stratum is represented in the sample, which can increase the precision of the estimates of the population parameters. Stratified random sampling is often used when the population has distinct subgroups or strata, and the goal is to obtain a representative sample from each stratum.

what if i am in the international space station approximately 240 miles above the surface of the earth. approximately how far away is the horizon?
The horizon is about 1,027 miles away if a person is in the international space station about 240 miles above the surface of the earth.
As a general rule, the horizon is located 2.9 miles away from an observer on the Earth's surface, and it is because of the planet's curvature. If a person moves up in the sky, the horizon line will also move up because the person's line of sight is increasing in distance.
In other words, if a person moves to a higher altitude, they will be able to see farther. The calculation to determine the distance of the horizon is based on the following formula:
D = √[(2Rh) + h²]
D is the distance to the horizon
R is the radius of the earth
h is the height above sea level of the observer in meters.
The radius of the Earth is about 6,371 kilometers, and it can be converted to meters by multiplying it by 1,000. The altitude of the International Space Station (ISS) is approximately 408 kilometers above the Earth's surface or 240 miles.
Using this information, we can calculate the distance to the horizon.
D = √[(2 * 6,371,000) + (408,000)²]D = √[(12,742,000) + (166,464,000,000)]D = √[166,476,742,000]D ≈ 408,216 meters
≈ 1,338,381.8 feet ≈ 403.6 km ≈ 252 miles
Therefore, if a person is on the International Space Station about 240 miles above the Earth's surface, the horizon will be around 1,027 miles away.

1. The line segment AB has endpoints A(-5, 3) and B(-1,-5). Find the point that partitions the line segment in

Answer:
To find the point that partitions the line segment AB in a ratio of 1:3, we can use the following formula:
P = (3B + 1A) / 4
where P is the point that partitions the line segment in a ratio of 1:3, A and B are the endpoints of the line segment, and the coefficients 3 and 1 represent the ratio of the segment we are dividing.
Substituting the values, we get:
P = (3*(-1, -5) + 1*(-5, 3)) / 4
P = (-3, -7)
Therefore, the point that partitions the line segment AB in a ratio of 1:3 is (-3, -7).

what are some issues you must consider when choosing the appropriate number of treatment conditions for your experiment? what does it mean to have conditions that are proportional to each other?
When selecting the appropriate number of treatment conditions, it is essential to consider factors such as resources, research complexity, and confounding variables.
Having conditions that are proportional to each other means that the level or intensity of each condition varies in direct proportion to the others, such that if one condition is increased or decreased, the others are also adjusted in a corresponding manner.
When choosing the appropriate number of treatment conditions for an experiment, there are several issues to consider. One of these is the ability to distinguish differences between treatment conditions.
A suitable number of treatment conditions for an experiment should be able to identify important differences between them. If there are too few treatment conditions, differences may not be identified, while if there are too many treatment conditions, resources may be wasted, making it difficult to obtain meaningful results.Another factor to consider is the need for replicability. The more treatment conditions that are used, the more difficult it is to replicate the experiment. A suitable number of treatment conditions should allow for replicability, meaning that the experiment can be repeated with similar results.To have proportional treatment conditions means that the levels of the independent variable (the treatment) are proportionate. This means that the differences between the levels of the independent variable are proportional to each other. This is important because it ensures that the treatment conditions are balanced and that the results obtained are valid. If the levels of the independent variable are not proportional, it can be difficult to interpret the results and draw conclusions.Having conditions that are proportional to each other means that the differences between treatment conditions are consistent across all levels of the independent variable. In other words, if the independent variable increases by a certain amount, the difference between the treatment conditions remains constant. This can be important for ensuring that the treatment effects are interpretable and generalizable to other populations.
