Answer:

The right answer is:

Option OB: f(1) = -9

Common difference: 7

Step-by-step explanation:

Given sequence is:

-9, -2, 5, 12,...

Here the first number is f(1)

Common Difference:

Common difference is the difference between consecutive terms of an arithmetic sequence. It is denoted by d.

In the given sequence,

f(1) = -9

f(2) = -2

f(3) = 5

$d=f(2)-f(1) = -2-(-9) = -2+9 = 7\\d = f(3)-f(2) = 5-(-2) = 5+2 = 7$

Hence,

The right answer is:

Option OB: f(1) = -9

Common difference: 7

Tyler bought 20 shares of Wal-Mart at $48.80. A year later, he bought 20 more shares at $54.60. He later sold all of his shares

NARA [144]

He bought last year and year later total is $104.3

Each share he sold 62.80 with tax is 0.03

62.80x1.03= $64.684 for each share
So there are 40 shares

64.684 x 40= $2587.36

<h2>Answer:</h2>

The value of the given expression is -27.

<h2>Given: </h2>

$\frac{x^{2}}{y}+\frac{x^{2}}{z}$

<h2>Step-by-step explanation: </h2>

In this problem, we need to solve the given expression in which we need to find the values of the variables. Since, the values of the variables are given, we can substitute the values and solve the equation as numerical calculation.

On substituting the values,

$\Rightarrow \frac{x^{2}}{y}+\frac{x^{2}}{z}=\frac{(6)^{2}}{-4}+\frac{(6)^{2}}{-2}$
