The answer would be 12n. You have to put like terms together. When you add 9n+3n, you get 12n. Then you would do 2+ (-2) which cancels out and becomes 0. That leaves you with 12n. :)

What is the least positive integer divisible by the numbers 2, 4, and 7?

Viefleur [7K]

Answer:

Least positive integer divisible by the numbers 2, 4, and 7 is 28

Step-by-step explanation:

We can find the least positive integer divisible by the numbers 2, 4, and 7 by taking the LCM

First lets List all prime factors for each number.

Prime Factorization of 2

2 is prime => $2^1$

Prime Factorization of 4 is:

2 x 2 => $2^2$

Prime Factorization of 7 is:

7 is prime => $7^1$

For each prime factor, find where it occurs most often as a factor and write it that many times in a new list.

The new superset list is

2, 2, 7

Multiply these factors together to find the LCM.

LCM = 2 x 2 x 7 = 28

Blake is a member of a golf club. When he became a member, he deposited money into his club account. For each round of golf that

Leno4ka [110]

Answer:

D) Blake's account initially had $320, which is decreasing at the rate of $20 per round.

Step-by-step explanation:

Here, according to the question:

x: The total number of golf rounds played

y: Represents the amount, in dollars, left in his account after playing x rounds

Let as assume A is the amount deposited initially.

y = A - n x here n : rate of each round played

Also, here

if x = 2, then y = 280

if x =4, then y = 240

If x = 2 and y = 280, then:

y = A - n x ⇒ 280 = A - 2 n ... (1)

If x = 4 and y = 240, then:

y = A - n x ⇒ 240 = A - 4 n ... (2)

Solving (1) and (2) by (1) - (2), we get:

40 = 2 n or, n = 20

Putting n = 20 in 280 = A - 2 n, we get: A = 280 + 2(20) = 320

⇒ A = $320, n = $20

⇒ The amount initially deposited is $320 and the rate per round is $20

Hence ,Blake's account initially had $320, which is decreasing at the rate of $20 per round.

You can recognize exponential and linear functions by their graph. Linear functions are straight lines while exponential functions are curved lines. You can also recognize them by the change in y. If the same number is being added to y, then the function has a constant change and is linear
