Answer:

d. $4x^2-7$

Step-by-step explanation:

The given functions are

$f(x)=4x+1$ and $g(x)=x^2-2$

We want to find the composition of the f and g.

$f(g(x))=f(x^2-2)$

We substitute $x^2-2$ into $f(x)=4x+1$ to obtain;

$f(g(x))=4(x^2-2)+1$

This simplifies to;

$f(g(x))=4x^2-8+1$

$f(g(x))=4x^2-7$

Hence the correct choice is d.

The number of customers on the first day are (6×-3) the number of customers on the second day is (×-1) how many more customers v

EleoNora [17]

The number of customers who visited more on first day = ( 5 x - 2)

<h2>248 more people visited on the first day. </h2>

Step-by-step explanation:

The total number of customers visiting on first day = (6 x - 3)

The total number of customers visiting on second day = (x - 1)

The difference in the number of customers

= Number of customer visiting ( First day - Second Day)

= (6x - 3) - (x- 1) = 6 x - 3 - x + 1 = 5 x - 2

So, the number of customers who visited more on first day = ( 5 x - 2)

Now, when x = 50, ( 5 x - 2) = (5 (50) - 2) = 250 - 2 = 248

Hence, 248 more people visited on the first day.

2) -2(7n – 6) +n=-3 - 8n

iogann1982 [59]

Answer and Step-by-step explanation:

For this equation the answer is : $n=3$

Step 1 : Simplify both the sides of the equation :

$-2(7n-6)+n=-3-8n$

$(-2)(7n)+(-2)(-6)+n=-3+-8n$ (Distribute)

$-14n+12+n=-3+-8n$

$(-14n+n)+(12)=-8n-3$ (Combine the like terms)

$-13n+12=-8n-3$

Step 2 : Add " $8n$ " to both the sides :

$-13n+12+8n=-8n-3+8n$

$-5n+12=-3$

Step 3 : Subtract " $12$ " from both the sides :

$-5n+12-12=-3-12$

$-5n=-15$

Step 4 : Divide both the sides by " $-5$ "

$\frac{-5n}{-5} =\frac{-15}{-5}$

$n=3$

That's your final answer : $n=3$
