I need help on this math problem

abruzzese [7]

Answer:

for the first one, simply add g(x) and h(x) :

x+3 + 4x+1 = 5x + 4

the second one, you would multiply them :

(x+3)(4x+1) = 4x^2 + 13x + 3

the last one, you would subtract :

(x+3)-(4x+1) = -3x + 2

and then substitute 2 for 'x' :

-3*2 + 2 = -6 + 2 = -4

a local dinner theater sells adult tickets for $105 and each children tickets for $ 60 each. for a certain show the theater sell

Sunny_sXe [5.5K]

Answer:

The theater sells 47 adult tickets and 37 children tickets

Step-by-step explanation:

Let

x = number of adult tickets sold

y = number of children tickets sold

1. A local dinner theater sells adult tickets for $105 each, then they get $105x selling x adult tickets and each children tickets for $60 each, then they get $60y selling y children tickets.

They make a total of $7,155, so

$105x+60y=7,155$

2. In total, the theater sells 84 tickets, so

$x+y=84$

3. Express y from the second equation

$y=84-x$

and substitute it into the first equation:

$105x+60(84-x)=7,155\\ \\105x+5,040-60x=7,155\\ \\105x-60x=7,155-5,040\\ \\45x=2,115\\ \\x=47\\ \\y=84-x=84-47=37$

Find all integers $n$ for which $\frac{n^2+n+1}{n-1}$ is an integer.

Grace [21]

$\dfrac{n^2+n+1}{n-1}=\dfrac{(n-1)^2+3(n-1)+3}{n-1}=n-2+\dfrac3{n-1}$

The remainder term $\dfrac3{n-1}$ will never vanish, and will always be rational as long as the denominator is not 1, 3, or -3.

$n-1=1\implies n=2$
$n-1=3\implies n=4$
$n-1=-3\implies n=-2$
