Write the explicit formula for the arithmetic sequence.

Mathematics
1 answer:
Ratling [72]3 years ago
3 0

Answer:

an = 9n -16

Step-by-step explanation:

First find the common difference, d

Take the second term and subtract the first

2 - (-7) = 2+7 = 9

We are adding 9 each time

Check 2+9 =11, check  11+9 = 20  check

The first term in the sequence is a1  so a1 =-7

an = a1 + d(n-1)

an = -7 + 9(n-1)

Distribute

an = -7 +9n-9

Combine like terms

an = 9n -16

the local theater is showing a matinee and offering a special deal for the community. A ticket for an adult costs $11 and a tick
Montano1993 [528]
We will call an adult ticket <em>a</em>, and a child ticket <em>c</em>.

Since they sold 60 tickets in total, we can form the equation:
a + c = 60

We can also say that the sum of money from the adult tickets and child tickets combined is 460.
Thus we can say
11a + 6c = 460

Now, we must solve our system.

a + c = 60
11a + 6c = 460

6a + 6c = 360
11a + 6c = 460

-5a = -100
a = 20

Thus, (20) + c = 60
c = 40

a = 20 and c = 40

What is the value of x in the equation 2(x−3) 9=3(x 1) x? x = −3 x = −1 x = 0 x = 3
Masja [62]

The solution of the linear equation is x = 0.

<h3>What is the linear equation?</h3>

An equation is a mathematical statement, which has an equal sign (=) between the algebraic expression.

Linear equations are the equations of degree 1.

The given linear equation is;

\rm 2(x-3)+ 9=3(x+ 1) +x

The value of x is determined in the following steps given below.\rm 2(x-3)+9=3(x+1)+x\\\\2x-6+9=3x+3+x\\\\\ 2x+3=4x+3\\\\3-3=4x-2x\\\\0=2x\\\\x=0

Hence, the solution of the linear equation is x = 0.
