Devon wants to write an equation for a line that passes through 2 of the data points he has collected. The points are (8, 5) and (–12, –9). He writes the equation
7x – 10y = 3. Is this a good model? Explain your reasoning.
Answer:
No. Correct is 7x - 10y = 6.
Step-by-step explanation:
The slope of the line is (-9-5)/(-12-8) = 7/10
y - 5 = 7/10(x - 8)
10y - 50 = 7(x - 8)
10y - 50 = 7x - 56
7x - 10y = -50 + 56
7x - 10y = 6.
Explanation:
Let's plug in x = 8 and y = 5. This is directly from the ordered pair (8,5).
7x - 10y = 3
7*8 - 10*5 = 3
56 - 50 = 3
6 = 3
We get a false equation at the end, which means the original equation is false when (x,y) = (8,5). Therefore, the point (8,5) is not on the line 7x-10y = 3. Furthermore it means that 7x-10y = 3 is not a good model since Devon wanted the line to pass through both given points.
If you were to plug in (x,y) = (-12,-9), then you would find the same thing happens. For each ordered pair, the left side results in 6. So if Devon were to change that "3" to "6", then it would be a good model as both points would be on the line. In other words, the standard form equation Devon should use is 7x-10y = 6. When solving for y, Devon would get y = (-7/10)x - 3/5
Below is visual confirmation that 7x-10y = 3 is not a good model. Both points are not on the line. The graph was made using GeoGebra.

Answer:
5x3 is 15 and 5x4 is 20. 15x 20 is 300…. Soo..
Step-by-step explanation:
You plan on joining a gym. The joining fee is $30 and you must pay $12 a month fee. If you have $100, how many months can you use the gym? Write and solve an inequality to represent the solution.
I need the process for this otherwise I won't get credit for it!!
Answer:
Inequality: 30+12x < 100
x ≈ 5 months
Step-by-step explanation:
To solve, first create the inequality. In this problem, 30 dollars is the flat fee for joining the gym and thus a constant. Additionally, 12 is the monthly payment and thus the coefficient for a variable because it changes with the number of months. Finally, 100 is the most that can be spent (the max), so it should be on the other side of the inequality and the sign should be less than or equal to 100.
This makes the inequality: 30+12x < 100
To find the number of months solve the inequality for x.
30+12x<10012x<70x<5.8So, the inequality equals x<5.8. However, the question asks for the number of full months. And, no more than 100 dollars can be spent. So, while you would normally round up. In this case, you must round down to 5 months.

The cost of admission to a festival was $112 for 9 children and 3 adults. The admission was $108 for 8 children and 3 adults in another festival. How much was the admission for each child and adult?
Answer:
cost of admission for each child was $4.00, and each adult was $25.33
Step-by-step explanation:
When solving questions like these , I like to break down the problem so I understand it better.
Let x ---> cost of the admission for each child
Y ---------> cost of the admission for each adult
9x+3y = 112 ---> equation A
8x + 3y = 108 ---> equation B
Subtract B from A
9x+3y=112
-8x+3y = 108
x = 112-108
x = 4
Find value of y by substituting value of x into equation
9(4)+3y=112
Solve for y
36+3y = 112
3y = 112=36
3y = 76
y = 25.33
55.99 dollars gift with 18% coupon and 7.25% sales tax. What is the final cost?
Answer:
I think it is $91.89.
Step-by-step explanation:
1. Take the number and add sales tax by multiplying 0.0725 ( since that is what the percentage is in a decimal form). Then add that to the original and you have what it would be plus sales tax: $60.05.
2. Then you would need to multiply by 0.18. You would get 10.809
3. Next, subtract the 10.809 from $60.05 and the answer is $49.24.

Answer:
Step-by-step explanation:
First off, divide 24 by 2 as that would give you the radius of the circle
24cm / 2cm = 12cm
Next, use the formula to calculate the circumference of a circle and plug in radius:
C = 2 x π x r
= 2 x π x 12cm
= 75.40cm is the circumference
