constant of proportionality is 4

equation: x/y = 4

explanation:
let's take 20 and 5 for example, if you divide 20 by 5, you will 4 of course. that's the proportionality for the first one. if you continue to divide x value by y value you will get 4. for the last two you would divide 28 by 4 and multiply 8 by 4.

Answer:

Constant: 4 i think because you can divide 20 by 4 to get 5 and 24 by 4 to get 6. So then probably the equation: is y=4x BUT DON'T PAY ATTENTION TO ME I GOT A B+ IN MATH:)

Answer:

(-2, -6 2/3), (-1, -6 1/3), (0,-6), (1,-5 2/3), (2, -5 1/3)

Step-by-step explanation:

For the values let's use -2,-1,0,1, and 2

The equation we need to use is slope-intercept (y=1/3x-6)

y=1/3(-2)-6

y=-2/3-6

y=-6 2/3

So the point for this one is (-2,-6 2/3)

Next, we'll plug in -1

y=1/3(-1)-6

y=-1/3-6

y=-6 1/3

The point for this one is (-1, -6 1/3)

Now we plugin 0

y=1/3(0)-6

y=0-6

y=-6

the point for this one is (0,-6)

Now we put in 1

y=1/3(1)-6

y=1/3-6

y=-5 2/3

the point is (1, -5 2/3)

Lastly, we plugin 2

y=1/3(2)-6

y=2/3-6

y=-5 1/3

The last point is (2, -5 1/3)

Hope you get a good grade!

C.

D.
54 minutes

Answers

The answer is c no problem !

Answer:

B: 36 minutes

Step-by-step explanation:

First, we need to find out how many minutes it takes him to run 1 mile.

63/7=9    So he runs 1 mile in 9 minutes.

To find out how far he runs in 4 minutes, simply multiply 9 by 4.

9*4=36

It will take him 36 minutes to run 4 miles.

Answers

Answer:

Just plug In values for x and find the output.

Step-by-step explanation:

If x is 1 then y is -1/3(1)+4, which is 11/3. (1, 11/3)

If x is 2 then y is -1/3(2)+4, which is 10/3. (2,10/3)

And so on...

Answer:

wow, congrats on moving up a math grade. sorry to hear you're struggling, hope I can help!

so the rule would be y = [tex]\frac{1}{3}[/tex]x + 4.

to start, say x = 2.

put that into the equation

y = (1/3*2) + 4

y = 2/3 + 4

y = [tex]4\frac{2}{3}[/tex] or 4.66

so if x = 2, y = [tex]4\frac{2}{3}[/tex]

try this again when x = 3.

put that into the equation:

y = (1/3 * 3) + 4

y = 1 + 4

y = 5

so if x = 3, y = 5

I can't put tables into brainly easily, but I hope this helps! goodluck!

Answers

Answer:

its -5 is the answer i thank.

Answer: -5

Explanation:
To solve this, plug in each of the answers as m (1, -5, -2, 5).

5(1) + 3 = 3(1) - 7
Answer: 8 = -4

5(-5) + 3 = 3(-5) - 7
Answer: -22 = -22

5(-2) + 3 = 3(-2) - 7
Answer: -7 = -13

5(5) + 3 = 3(5) - 7
Answer: 28 = 8

And as you can see, m = -5 gives us the answer -22 = -22, which is correct.

The reason why I say that is because 5(29) you would have to Multiply 20 to 5 and 9 to 5 to get the answer. Then 4(35) will also be split 4(30+5) and do the same. And the 25 would stay the same. And 8(5) is also knows as 8 x 5 which gives you 40.
