The second one is y=-3x-1
3rd is y =-x-1
4th is y=0.5x+2
Hope this helps
Answer:
please see answers below
Step-by-step explanation:
equation of a straight line is given by y= mx + c (where m is gradient-slope, c is y-axis intercept)
you have to measure the slope (change in y values ÷ change in x values).
you have to find where graph crosses the y-axis (y-axis intercept).
pick two sets of coordinates for each line (graph).
1) coordinates are (0,2) and (10,7).
slope = (change in y values ÷ change in x values)
= (7 - 2) / (10 - 0) = 5/10 = 1/2.
it crosses the y-axis at y = 2.
the equation is y = (1/2)x + 2.
2) coordinates are (0, -3) and (2, 5).
slope = (-3 - 5) / (0 - 2)
= -8 / -2
= +4
=4.
it crosses the y-axis at y = -3
the equation is y = 4x - 3
3) coordinates are (-1, 0) and (1, -2)
slope = (-2 - 0) / (1 - -1)
= -2 / (1 + 1)
= -2 /2
= -1 .
it crosses the y-axis at y = -1
the equation is y = -x - 1
4) coordinates are (-1, 2) and (0, -1)
slope = (-1 - 2) / (0 - -1)
= -3 / (0 + 1)
= -3/1
= -3.
it crosses the y-axis at y = -1
the equation is y = -3x - 1
5) coordinates are (4, 0) and (0, 2).
slope = (2 - 0) / (0 - 4)
= 2/-4
= -1/2
it crosses the y-axis at y = 2
the equation is y = -(1/2)x + 2
hope these answers help you. good luck

A researcher conducts an experiment comparing two treatment conditions and obtains data with 10 scores for each treatment condition.
a. If the researcher used an independent-measures design, how many subjects participated in the experiment? Explain how many samples will be needed, how many subjects, and what is the total subjects
b. If the researcher used a repeated-measures design, how many subjects participated in the experiment? would the repeated â€"measures design use the same sample of n-10 and will there be 10 subjects in both treatment conditions.
c. If the researcher used a matched-subjects design, how many subjects participated in the experiment?
Answers
a. In an independent-measures design, each treatment condition has its own separate group of subjects.
Therefore, the number of subjects participating in the experiment would be equal to the sum of subjects in both treatment conditions.
In this case, there are 10 scores for each treatment condition, so there would be a total of 10 + 10 = 20 subjects in the experiment.
b. In a repeated-measures design, the same subjects are exposed to both treatment conditions. Therefore, the number of subjects participating in the experiment would be the same as the number of subjects in each treatment condition. In this case, there are 10 scores for each treatment condition, so there would be a total of 10 subjects in the experiment.
c. In a matched-subjects design, each subject is matched or paired with another subject based on specific criteria. The number of subjects participating in the experiment would depend on the matching criteria and the number of matched pairs.
Since the information about the matching criteria is not provided, it is not possible to determine the exact number of subjects in this design. The number of subjects in a matched-subjects design can vary depending on the specific study design and requirements.

The floor of a canyon has an elevation of −14. 5 feet. Erosion causes the elevation to change by −1. 5 feet per year. How many years will it take for the canyon floor to have an elevation of −31 feet?.
Answers
It will take 11 years for the canyon floor to have an elevation of −31 feet.
Define equation.A mathematical statement known as an equation makes two expressions' values equal. It is a mathematical statement that says "this is equivalent to that," in other words. The left side appears to be a mathematical expression, the centre appears to be an equal sign, and the right side is another mathematical expression. The right side of the equation frequently has a value of zero.
Given,
The first step in this situation is to define the variables.
So, we have:
x: the age in years
y: height in feet
The equation used to model the issue is then written.
So, we have:
y = 1.5x - 14.5
Then, at a -31 foot elevation, we have:
-31 = 1.5x - 14.5
For years,
x = -16.5/1.5
x = 11
In 11 years it will take for the canyon floor to have an elevation of −31 feet.

A research paper claims a meaningful contribution to the literature based on finding statistically significant relationships between predictor and response variables. In the footnotes, you see the following statement, "given this research was exploratory in nature, traditional levels of significance to reject the null hypotheses were relaxed to the .10 level."
critically evaluate this footnote.
what response to provide to the authors about this footnote?
Answers
The footnote in the research paper states that the traditional levels of significance to reject the null hypotheses were relaxed to the 0.10 level because the research was exploratory in nature. This statement suggests that the researchers intentionally chose a higher level of significance in their statistical analysis.
In response to this footnote, you could provide the authors with the following feedback:
1. Acknowledge the exploratory nature of the research: Begin by recognizing that the authors mentioned the exploratory nature of their study in the footnote. This indicates that they were conducting preliminary investigations or searching for patterns and relationships without any preconceived hypotheses.
2. Explain the concept of statistical significance: Provide a brief explanation of statistical significance, which refers to the probability that the observed relationship between variables is not due to chance. Emphasize that traditionally, a significance level of 0.05 is commonly used to determine whether the relationship is statistically significant.
3. Discuss the rationale for relaxing the significance level: Address the authors' decision to relax the significance level to 0.10. Explain that by doing so, they are allowing for a higher chance of finding statistically significant relationships between the predictor and response variables. This decision may be justified in exploratory research, as it allows for a more liberal approach to hypothesis testing.
4. Highlight the implications of relaxed significance levels: Explain that relaxing the significance level increases the likelihood of finding statistically significant results, even if the true relationships are weak or non-existent. This could lead to an increased risk of Type I errors, where a relationship is detected when there isn't one. It is important to note that relaxed significance levels may generate preliminary findings that require further validation.
5. Suggest additional analysis or caution: Finally, recommend that the authors interpret their findings with caution and consider conducting further research to validate their results. Additionally, they may want to include sensitivity analyses to understand the impact of different significance levels on their conclusions. Encourage them to discuss the potential limitations and implications of their decision to relax the significance level in the paper.
Remember to maintain a respectful and informative tone throughout your response. By providing this feedback, you are helping the authors understand the implications of their choice to relax the significance level and encouraging them to critically evaluate their findings.

the proof that ux ≅ sv is : △stu an equilateral triangle∠txu ≅ ∠tvsprove: ux ≅ sv
Answers
Based on the information of an equilateral triangle △STU and the congruence of angles ∠TXU and ∠TVS, it can be concluded that UX is congruent (≅) to SV. The proof involves establishing the congruence of corresponding angles and applying the angle-angle (AA) congruence criterion.
To prove that UX is congruent (≅) to SV using the information, we will utilize the fact that △STU is an equilateral triangle and the congruence of angles ∠TXU and ∠TVS.
We have:
△STU is an equilateral triangle (∠STU = ∠TUS = ∠UST = 60 degrees)
∠TXU ≅ ∠TVS
Proof:
1. Draw a diagram of equilateral triangle △STU.
2. Draw a line segment UX and SV originating from U and S, respectively, towards the interior of the triangle.
3. ∠TXU and ∠TVS are congruent (given).
4. ∠STU = ∠TUS = ∠UST = 60 degrees (equilateral triangle property).
5. Since ∠STU and ∠TUS are both equal to 60 degrees and ∠TXU ≅ ∠TVS, we can conclude that ∠UTX ≅ ∠VTS (angle sum property of triangles).
6. By Angle-Angle (AA) congruence, ∆UTX ≅ ∆VTS.
7. Since corresponding parts of congruent triangles are congruent, we have UX ≅ SV (side UT ≅ side VT).
Therefore, we have proved that UX is congruent (≅) to SV using the information.

Use the Buying a Car information above to answer this question. What is your monthly payment if you choose 0% financing for 48 months? Round to the nearest dollar. Use the Buying a Car information above to answer this question. The rebate offer is $2900, and you can obtain a car loan at your local bank for the balance at 5.24% compounded monthly for 48 months. If you choose the rebate, what is your monthly payment? $ Round to the nearest dollar.
Answers
If you choose the rebate offer, your monthly payment for the car loan at the bank will be approximately $557 (rounded to the nearest dollar).
To calculate the monthly payment for each financing option, we'll use the information provided:
1. 0% financing for 48 months:
Since the financing is offered at 0% interest, the monthly payment can be calculated by dividing the total purchase price by the number of months.
Purchase Price: $26,050
Number of Months: 48
Monthly Payment = Purchase Price / Number of Months
Monthly Payment = $26,050 / 48 ≈ $543
Therefore, the monthly payment for the 0% financing option for 48 months is approximately $543.
2. Rebate offer and car loan at the bank:
If you choose the rebate offer, you'll need to finance the remaining balance after deducting the rebate amount. Let's calculate the remaining balance:
Purchase Price: $26,050
Rebate Offer: $2,900
Remaining Balance = Purchase Price - Rebate Offer
Remaining Balance = $26,050 - $2,900 = $23,150
Now, we'll calculate the monthly payment using the remaining balance and the loan terms from the local bank:
Remaining Balance: $23,150
Interest Rate: 5.24% (compounded monthly)
Number of Months: 48
Monthly Payment = (Remaining Balance * Monthly Interest Rate) / (1 - (1 + Monthly Interest Rate)^(-Number of Months))
First, let's calculate the Monthly Interest Rate:
Monthly Interest Rate = Annual Interest Rate / 12
Monthly Interest Rate = 5.24% / 12 ≈ 0.437%
Now, we can calculate the Monthly Payment using the formula mentioned above:
Monthly Payment = ($23,150 * 0.437%) / (1 - (1 + 0.437%)^(-48))
Monthly Payment ≈ $557
Therefore, if you choose the rebate offer, your monthly payment for the car loan at the bank will be approximately $557 (rounded to the nearest dollar).
