For the answer to the question above asking to <span>Find a rational number that is between 9.5 and 9.7. Explain why it is rational. </span>
I think the answer is 9.6, because it does not have a repeating or continuous decimal.
I hope my answer helped you.

A summer camp cookout is planned for the campers and their families. There is room for 525 people. Each adult costs $9, and each
vodomira [7]

Answer:

<em>The System of Inequalities in this real-world scenario is:</em>

x+y < = 525

9x+5y < = 1200

Step-by-step explanation:

In this question we are asked to to write a system of inequalities, thus a system of relating two variables, where the relationship will be of the form either greater > or less < or equal.  

<u>Given Information:</u>

→ Maximum number possible in the summer camp: 525

→ People attending are Adults (lets call them x and Campers (lets call them y)

→ Ticket Cost for Adults is $9

→ Ticket Cost for Campers is $5

→ Maximum budget available for both Adults and Campers is $1200

From these information we can obtain 2 Inequalities to define our system of equation.

The first inequality will be with respect to the Maximum Number of People possible which reads as:

x+y\leq 525         [sum of adults and campers should be less or equal to maximum number of people possible]

The second will be with respect to the Maximum Budget available which reads as:

9x+5y\leq 1200         [sum of the cost per ticket for adults and campers should be less or equal to maximum budget available]

<em>Thus the System of Inequalities in this real-world scenario is:</em>

x+y\leq 525\\9x+5y\leq 1200

<em>Which if solved can give us the values for x and y, thus the number of adults and numbe of campers attedning the summer camp. </em>

Consider the linear system of equations y=2/5x-1 and 2x-3y+1=0 graph the system of equations
nlexa [21]

We can see that the lines intersect at: (-5,-3)

Step-by-step explanation:

Given system of equations is:

y = \frac{2}{5}x-1\ \ \ \ Eqn1\\2x-3y+1 = 0\ \ \ \ Eqn2

Lets convert the second equation in the same form as the first equation

2x-3y+1 = 0

Adding 3y on both sides

2x-3y+1+3y = 0+3y\\2x+1 = 3y\\3y= 2x+1

Dividing both sides by 3

\frac{3y}{3} = \frac{2x+1}{3}\\y = \frac{2}{3}x+\frac{1}{3}\\

The graph of equation can be plotted using manual graphing or any online graphing calculator

We will use the Desmos online graphing calculator to graph the equations (Picture attached)

We can see that the lines intersect at: (-5,-3)

Find f(x) if it is known that f(x+3)=4x+12.
MArishka [77]

Solution:

we are given that

f(x+3)=4x+12

we have been asked to find f(x).

we can find the value of f(x) by re-writing the given function in the form of f(x+3) and thereafter we will replace (x+3) by x.

we can re-write the given function as below

f(x+3)=4(x+3)\\\\\Rightarrow f(x)=4x\\

Hence the expression representing f(x) is f(x)=4x+3.
