If y varies directly with x, and y = 18 when x = 4, what is the constant of proportionality?

Y is directly proportional to x and therefore takes the form y=kx where k is the constant of proportionality.

Dividing both sides by x for the given values, k becomes 18/4 = 4.5

I require assistance once again.​
stealth61 [152]

Answer:

I can help you with 1, 2 and 3.

Step-by-step explanation:

1. 2x + 3y = 1470

Subtract 2x from both sides: 3y= -2x+1470

Divide three from both sides: y= \frac{-2}{3}x +490

2. To graph it, you would first go to (0,490) because that is where the y-intercept is. Since slope is ride over run, you can either go up 2 left3 or down 2 right 3. You can proceed doing that until you have enough points to draw the line.

3. f(x)= -2/3x +490. This function means represents how many wraps are sold based on how many rolls are sandwich.

1. 2 |-9| <br> 2. 4 |-4| <br> 3. 1 |1| <br> 4. 11 |11| <br> 5. 9 |-2|
Zielflug [23.3K]

The absolute value is the distance the number is from zero. For example, the absolute value of -4 is 4 and the absolute value of 4 is 4. Also |-24| is 24.

The absolute value of -9 is 9. 2 times 9 is 18.

The absolute value of -4 is 4. 4 times 4 is 16.

The absolute value of 1 is 1. 1 times 1 is 1.

The absolute value of 1 is 11. 11 times 11 is 121.

The absolute value of -2 is 2. 9 times 2 is 18.

The opposite of a number is the difference it is from zero but on the other side (opposite sign). For example, the opposite of -5 is 5, and the opposite of 2 is -2.

11 is opposite of -11.

-8 is opposite of 8.

31 is opposite of -31.

-1 is opposite of 1.

-17 is opposite of 17.

And DVD cost $26.75 before sale tax sale tax is 7.5% what is the total of cost of DVDs
blondinia [14]
First let's convert 7.5% into a decimal by doing Beyoncé on it and move the decimal two places to the left.

7.5\% = 0.075

Now let's multiply the cost of the DVD by the converted percent,

26.75 \times 0.075 = 2.00
Now let's add the above number to the original price, remember, $2 is not exact.

26.75 + 2.00 = 28.75
~~

I hope that helps you out!!

Any more questions, please feel free to ask me and I will gladly help you out!!
