If m &gt; n, which inequalities must be true? Check all that apply.
ololo11 [35]

Step-by-step explanation:

m > n         <em>add 2.1 to both sides</em>

m + 2.1 > n + 2.1         TRUE

m > n      <em>subtract (-4) from both sides</em>

m - (-4) > n - (-4)       TRUE

m > n       <em>add 16.5 to both sides</em>

16.5 + m > 16.5 + n     TRUE

m > n → 3 + m > n       <em>logic</em>

3 + m > n       <em>add 6 to both sides</em>

9 + m > 6 + n         TRUE

Given that k(x) = (2x + 4)2
taurus [48]

Answer:

f(x)=4x\\g(x)=x+2

Step-by-step explanation:

Because we have to rewrite this equation in the format f(g(x)), we have to divide, or factor to find basic terms,

Expanding the value of k(x), we have k(x)=4x+8. We see that each term can be divisible by 4, so we can factor out 4 to get

k(x)=4(x+2)

Now, we have two different terms getting multiplied. We can separate the two to get 4 \text{ and} (x+2)

Because we are multiplying 4 by the other term, this is represented by 4x

Now, we can just set f(x) and g(x) to these functions:

f(x)=4x\\g(x)=x+2

Now, just to make sure, we can plug a value into k(x) and the same value into f(g(x)). Plugging in 1, we have (2(1)+4)2 as 2(2+4), which is 2(6) = 12.

Plugging 1 into f(g(x)), we can evaluate g(1) first, to get 1 + 2 = 3. Now, f(3) = 4(3)= 12, which is the same for k(x).
