This is called a difference of squares which always factors according to the rule for factoring the difference of squares....

(a^2+b^2)=(a+b)(a-b) in this case:

Step-by-step explanation:

To find (g ￮ f)(x), substitute x = f(x) into g(x) , that is

g(2x - 5)

= 3(2x - 5) + 4

= 6x - 15 + 4

= 6x - 11 → C

Which lists the steps in the correct order to find the median of this data set? 24, 16, 23, 30, 18, 29 O 1. Put the numbers in o

timofeeve [1]

Median is the central tendency of the data and always exists in the middle of the data set.

<h3>What is the median?</h3>

The Median is the middlemost value of the numbers arranged in the ascending orders. Median is the central tendency of the data and always exists in the middle of the data set.

The process of finding the median if the number of data points is even is as follows:

Put the numbers or the data points in the order(increasing or decreasing i.e. ascending or descending order)
Next cross of the high/ low pairs
Add the leftover numbers
and divide the number( as obtained in the above step by 2)

( if the number of data pints were even then we just need to arrange the numbers and cross the high/low pair and only one data point will be left which acts as the Median of the data set)

James just began a job as a nurse. He is given a starting salary of $66,640 per year. He is also told that his salary will incre

Leto [7]

Answer:

the rate of change of James’ salary is $845 dollars per year

y = 845x + 66640

the value of James’ salary in 23 years=$86,075

Step-by-step explanation:

Let x = the years worked and y = Salary in dollars

When x=0 then y = 66640

when x= 8 then y = 73400

Two points are (0,66640) and (8,73400)

Rate of change of salary is the slope

To find slope we use formula

$slope = \frac{y_2-y_1}{x_2-x_1} =\frac{73400-66640}{8-0} =845$

the rate of change of James’ salary is $845 dollars per year

Slope intercept form of equation is y=mx+b

m = 845 , b is the y intercept (initial salary)

so y = 845x + 66640

Now we find out salary in 23 years

plug in 23 for x in the y equation

y = 845x + 66640

y = 845(23) + 66640=86075

the value of James’ salary in 23 years=$86,075
