4x-4>20

Step 1: Add four to both sides
4x-4+4>20+4
4x>24
Step 2: Divide both sides by 4
4x divided by 4 and 24 divided by 4
Answer: x>6
Kahal accidentally subtracted instead of adding. He made a mistake in step 2.

Answer:

$\boxed{f(6) = 34}$

Step-by-step explanation:

Composition of functions occurs when we have two functions normally written similar or exactly like f(x) & g(x) - you can have any coefficients to the (x), but the most commonly seen are f(x) and g(x). They are written as either f(g(x)) or (f o g)(x). Because our composition is written as $(f \circ g)(2)$ , we are replacing the x values in the g(x) function with 2 and simplifying the expression.

$g(2) = 3(2)$

$g(2) = 6$

Now, because we are composing the functions, this value we have solved for now replaces the x-values in the f(x) function. So, f(x) becomes f(6), and we use the same manner as above to simplify.

$f(6) = (6)^2-2$

$f(6) = 36-2$

$f(6) = 34$

Therefore, when we compose the functions, our final answer is $\bold{f(6) = 34}$ .

Jorge finds that 56% of his 75 classmates like salsa music and 80% of his 60 relatives like salsa music how many more of Jorge’s

Natasha_Volkova [10]

<span>To solve this problem you must apply the proccedure shown below:
1. You have the following information given in the problem above:
- There are 75 classmates.
- 56% of his 75 classmates like salsa music and 80% of his 60 relatives like salsa music.
2. Therefore, you have:
- Number of his classmates that likes salsa music:
75x0.56=42
- Number of his r</span>elatives that like salsa music:
60x0.80=48
3. Then you have:
48-42=6
Therefore, the answer is: 6.

MULTIPLE CHOICE 9th grade math: help me find the formula to the nth term:

maxonik [38]

Answer:

$a_{n}$ = - 5n - 2

Step-by-step explanation:

There is a common difference between consecutive terms, that is

- 12 - (- 7) = - 17 - (- 12) = - 5

This indicates the sequence is arithmetic with n th term

$a_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 7 and d = - 5, then

$a_{n}$ = - 7 - 5(n - 1) = - 7 - 5n + 5 = - 5n - 2
