3 new clients each week. Use an arithmetic sequence to write a function to represent this real-world situation and determine the range of the function for the first four weeks of data.
A.
f( x) = 3x + 26;0 \leqslant y \leqslant 4
B.
f(x) = 3x + 26;26 \leqslant y \leqslant 35
C.
f(x) = 3x + 23;26 \leqslant y \leqslant 35
D.
f(x) = 3x + 23;0 \leqslant y \leqslant 4

<h2>Answer:</h2>

Option: B. is the correct answer.

  B.   f(x)=3x+26\ ;\ 26\leq y\leq 35

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

It is given that:

A-mowing company is trying to grow its business. It had 26 clients when they started.

It had 26 clients when they started its business and wants to increase by 3 new clients each week.

i.e. if x represents the number of week, then the function which represents the number of clients is:

f(x)=3x+26

( Also, the range of the function is the set of all the values which are attained by a function in it's domain)

We are asked to find the range of the function for the first four weeks of data.

i.e. when x=0,1,2 and 3

i.e. x=0 is the initial week i.e. the first week when it was started.

x=1 is the second week after the start and so on.

Hence, we have:

the range as:   26\leq y\leq 35

Answer:

B. f(x) = 3x + 26;26≤ y ≤ 35

Step-by-step explanation:

This would be a linear equation in the form

y= mx+b

where b is the initial value (or 26 clients)

m is the slope, or the amount they want to increase by each week

y = 3x+26

Let x =0

y = 26 or what we start with

Let x =3, or be week 4 (we started with x= 0)

y = 3*3 +26

y =9+26

y= 35

Is the relationship between the amount of gas and pressure direct or indirect? Explain your answer
guajiro [1.7K]

Answer:

INDIRECT!

see below

Step-by-step explanation:

A law that says that if the temperature is constant then  the volume of a fixed amount of a gas is <u>inversely proportional</u> to its pressure.If the pressure on a gas increases, the volume of the gas decreases because the gas particles are getting closer together.

X - 3 = 7 pls help step by step explanation
PtichkaEL [24]

Answer:

x = 10

Step-by-step explanation:

First, to solve for x, you need to isolate the variable, meaning that it needs to be the only term on one side of the equation. To do this, we'll just cancel out the -3 by adding +3 on both sides of our equation.

x - 3 = 7

 +3    +3

x = 10

Leaving us with our answer, x = 10

Hope this helped :)

What is 9c+90&lt;-27?????​
antoniya [11.8K]
<h3>Answer:  c < -13</h3>

========================================

Work Shown:

9c + 90 < -27

9c + 90 - 90 < -27 - 90 .... see note 1

9c < -117

9c/9 < -117/9 ... see note 2

c < -13

-----------

note 1: I'm subtracting 90 from both sides to undo the "plus 90" that is happening on the left side

note 2: I divided both sides by 9 to undo the multiplication. The expression 9c is the same as 9*c or "9 times c". The inequality sign will <u>not</u> flip as we are dividing both sides by a positive number.
