Answer:
The following points are on the line
(x,y) = (2,120)(x,y) = (3,180)(x,y) = (4,240)There are other points on the line, but I'm focusing on the points where the three filled in circles are shown. I'm ignoring (0,0) because that point won't be useful for the next section below.
Pick any of the three points and divide y over x
y/x = 120/2 = 60y/x = 180/3 = 60y/x = 240/3 = 60Whatever point you choose, you'll get the same ratio. The constant of proportionality is 60.
In the context of this problem, the 60 refers to the speed of the car.
The car travels 60 miles in 1 hour, or at a speed of 60 mph.

You live 6 miles from school. if you start walking from school at 3:00, and your best friend starts skateboarding from school towards youe home at the same time, what time will you meet and how far from your home? your speed is 3.5 miles/hour, and your friends speed is 6 miles/hour
Answers
Answer: 2 hrs 40 min
Step-by-step explanation: Ok I might be wrong so try to do other people's answers instead of mine.
So your friend is going 6 miles per hour, so he/she will be there in an hour
But you are going 3.5 miles an hour.
So what I did was divide 3.5 by 5 and 60 by 5 and found out that you are going 0.5 miles every 20 min. Then I added up the distance and time and got 6 miles every 2 hrs and 40 min
REMINDER: I might be wrong because I haven't done this question before, but tell me if I'm right or not! :D

type the slope intercept equation of the line that passes through the points (5,2) and (4,1)
Answers
Answer:
y = x - 3
Step-by-step explanation:
Answer:
Y= x-3
Step-by-step explanation:
The distance from our y values is -1.
The distance from our x values is -1.
Rise/ Run = Y/X
-1/-1 = 1 or 1/1
You would rise 1 and run 1!
You can use this strategy if you're using graph paper to eventually get the y intercept which is -3.
Hope this helps! :)

Find the distance between the two points in simplest radical form.
(8, – 7) and (1, -1)
Answers
Answer:
The distance between the two points is [tex]\sqrt{85}[/tex] units
Step-by-step explanation:
Let us revise the rule of the distance between two point [tex](x_{1},y_{1})[/tex] and [tex](x_{2},y_{2})[/tex]
[tex]d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]
∵ We need to find the distance between the two points (8, -7) and (1, -1)
→ Let [tex]x_{1}[/tex] = 8 and [tex]x_{2}[/tex] = 1
→ Let [tex]y_{1}[/tex] = -7 and [tex]y_{2}[/tex] = -1
→ Substitute their values in the rule above
∴ [tex]d=\sqrt{(1-8)^{2}+(-1--7)^{2}}[/tex]
∴ [tex]d=\sqrt{(-7)^{2}+(-1+7)^{2}}[/tex]
∴ [tex]d=\sqrt{49+36}[/tex]
∴ [tex]d=\sqrt{85}[/tex]
→ Simplify the radical
∵ 85 = 5 × 17
→ Both of them are prime numbers
∴ The simplest form of [tex]\sqrt{85}[/tex] is [tex]\sqrt{85}[/tex]
∴ The distance between the two points is [tex]\sqrt{85}[/tex] units

Answer:
1 of 8: (729, 81, 9, 1)
2 of 8: 1 = (-1)^0 = 2^0
3 of 8: 1
Step-by-step explanation:
The basic rule is that any non-zero value to the zero power is 1. It doesn't matter whether the value is positive or negative. Raising it to the zero power makes it 1.
So, for question 2 of 8, the two equivalent expressions can be anything raised to the zero power (or anything with a value of 1, for that matter).

Apply the distributed property, so it now looks like this: 3a + 9 + 6 = 30Simplify: 3a + 15 = 30Subtract 15 from each side, so it now looks like this: 3a = 15Divide each side by 3 to cancel out the 3 next to a. It should now look like this: a = 5I hope this helps!
M = 2/3, B = -5
M = -5, b = 3/2
M = 2, b = -6
M = -5, b= 2
Answers
Answer: m = 3/2, b = -5
Step-by-step explanation:
When we input these values into slope-intercept form y = mx + b, then we get y = 3/2x -5. When trying out different x values, we get the same points that are on the line such as (2, -2) also the y-intercept is -5, so we know it is a true statement and that the slope 3/2 and y-intercept -5 are the only correct answers for this line.

A symphony orchestra is arranged in a semicircle around the conductor. The rows are about 3 feet apart, with the first row about 6 feet from the conductor. A mid-sized orchestra has about 6 rows of chairs. What is the approximate delay between the instant when a play at the 6th row start a note and when the conductor hears the note?
Answers
Answer:
19 ms
Step-by-step explanation:
We need to find the time it takes for the sound from the 6th row gets to the conductor.
Since there are 6 rows and each row is 3 feet apart, since the orchestra is arranged in a semi-circular manner around the conductor, the distance from the 6 th row to the 1st row is (6 - 1) × 3 = 5 × 3 = 15 feet.
Now, since the conductor is 6 feet from the first row, his distance from the 6th row is 15 feet + 6 feet = 21 feet.
So, time approximate delay between the instant when a play at the 6th row start a note and when the conductor hears the note, t = distance between 6th row and conductor/speed of sound.
Speed of sound = 343 m/s
distance between 6th row and conductor = 21 feet. In meters, it is 21 × 0.3048 m = 6.4008 m
t = 6.4008 m ÷ 343 m/s
= 0.019 s
= 19 ms
