Answer: 17 campers attended last year

Step-by-step explanation:

Let x be the number that attended last year.

The number of campers this year (23) is equal to 2 times the number of last year (x), minus 11.

23 = 2x – 11

23 + 11 = 2x

34 = 2x

34/2 = x

17 = x

The population of Farmersville can be modeled by the inequality y > 2,000x + 2,100, where x is the number of years since 2010
Kaylis [27]

Answer:

The population can be greater than 6,100 but less than 6,300, and thus, we cannot determine if the population of Farmersville will be greater than 6,300 in 2012.

Step-by-step explanation:

Inequality for the population of Farmsville:

The inequality for the population of Farmsville in x years after 2010 is given by:

y(x) > 2000x + 2100

Will the population of Farmersville be greater than 6,300 in 2012?

2012 is 2012-2010 = 2 years after 2010, so we have to find y(2).

y(2) > 2000(2) + 2100

y(2) > 6100

The population can be greater than 6,100 but less than 6,300, and thus, we cannot determine if the population of Farmersville will be greater than 6,300 in 2012.

Wapi simplified an expression. His work is shown below.
-BARSIC- [3]

Answer:

Step 3

Step-by-step explanation:

7( 8.5-1.5) +8 ÷2

PEMDAS

Parentheses

7*7 +8 ÷2

Then multiplication and division from left to right

49 +8 ÷2

We are still on multiplication and division

49+4

So step 3 is the first mistake

Simplify -12x^4/x^4+8x^5
alexgriva [62]

Answer:

OPTION A: $ \frac{12}{1 + 8x} $, where $ x \ne - \frac{1}{8} $.

Step-by-step explanation:

Given: $ \frac{- 12x^4}{x^4 + 8x^5} $

Taking $ x^4 $ common outside in the denominator, we get:

$ = \frac{-12x^4}{(x^4)(1 + 8x)} $

$ x^4 $ will get cancelled on the numerator and denominator, we get:

$ = \frac{-12}{1 + 8x} $

we know that the denominator can not be zero.

That means, 1 + 8x $ \ne $ 0.

$ \implies 8x \ne -1 $

$ \implies x \ne \frac{-1}{8} $

So, the answer is: $ \frac{-12}{1 + 8x} $, where $ x \ne \frac{-1}{8} $.
