(f ○g ) (2)= 11

Step-by-step explanation:

(f ○g ) (x)= (f(g(x))

= 5( x² -1) – 4

= 5x² – 5 – 4

= 5x² – 9

(f ○g ) (2)= (f(g(2)) = 5 (2)² – 9 = 5(4) – 9 = 20 – 9 = 11

I hope I helped you^_^

1. Determine the median of this data set.

Simora [160]

1) When finding a median, order your numerical list from smallest to larger, as so: 2,2,3,4,5,6,8,9.
2) Then start eliminating numbers from each side of the order; (The bolded numbers will be removed.)
2,2,3,4,5,6,8,9
2,3,4,5,6,8,9
  2,3,4,5,6,8
3,4,5,6,8
  3,4,5,6
4,5,6
  4,5
3) Since there is an even number of digits in your list, you will have to add the last two digits and then divide them by two. 4 and 5 are the last numbers standing, (4+5=9)(9/2=4.5) and therefore your answer, would be 4.5, or B.

CHCK Farms raises hens and roosters. They have enough space to raise at most 300 birds per year. Each hen eats 80 pounds of food

svp [43]

Answer:

The number of hens is 100 and the number of roosters is 200.

Step-by-step explanation:

Let the number of hens be x and the number of roosters be y

then the total number of hens and roosters, is 300

so,

$x+y \leq 300$ ----------------------------(1)

Also the hen eats 80 pounds of food per year and roosters eats 60 pounds of food per year,

$80x+60y \leq 20000$ ----------------(2)

To solve the equations , multilpy eq(1) by 80

$80x+80y \leq 24000$ ------------------(3)

Subracting (2) from (3)

$20y \leq 4000$

$y \leq 200$

substituting y in eq(1) we get

$x+200 \leq 300$

$x \leq 300-200$

$x \leq 100$

Rewrite each expression by combining like terms. 8pq - 3pq 2m - 3m + 4

qaws [65]

Answer:

8pq-3pq= 5pq
2m-3m+4 =4-m

Step-by-step explanation:

The first equation shows two terms can be combine as follow: 8pq-3pq= (8-3)pq by applying common factoring. Then, because 8-3=5, it can be expressed as 5pq.
In the second equation, we have only two terms that can be factored by combining the terms that share the same factor (which is m). Then, 2m-3m+4 can be expressed like m(2-3)+4. Because (2-3)=-1 and because the order of the sum does not affect the result, the result is 4-m.

Geometry help! Picture included :)

AURORKA [14]

Set up a proprtion and cross multiply.

18/7.5=22/4x+1

7.5×22=18 (4x+1)
165=72x+18
147=72x
x=2.04
