How do you prove if quantities vary directly?
Cerrena [4.2K]

Answer:


Step-by-step explanation:

If quantities vary directly, then one is simply the other multiplied by a fixed number. All sets of two numbers in a direct variation are one number multiplied by a fixed number to get the second number.

Example:

1 gallon of gasoline costs $3.50

2 gallons of gasoline cost $7.00

3 gallons of gasoline cost $10.50

Is the price of gasoline a direct variation based on the number of gallons?

3.5/1 = 3.5

7/2 = 3.5

10.5/3 = 3.5

When you multiply 1 gal, 2 gal, and 3 gal by the constant number 3.5 $/gal, you get the price. Since the multiplication is always by the same number, it is a direct variation.

I NEED HELP WITH THIS ASAP!!
vitfil [10]

Answer: 78°

Step-by-step explanation:

Looking at the picture, we can tell that ∠ACD and ∠DCB are supplementary angles. This means, they are equal to 180°. With that, we can find x and plug it into ∠DCB.

4x+2+3x+3=180            [combine like terms]

7x+5=180                       [subtract both sides by 5]

7x=175                           [divide both sides by 7]

x=25

Now that we know x=25, we can plug it in to find ∠DCB.

3(25)+3                         [multiply]

75+3                               [add]

78

Now, we know ∠DCB is 78°.
