$\huge\text{Hey there!}$

$\large\boxed{\mathsf{x - 3y^3 + 3x^3 - 5x - x^3 - x - 2x^3}}$

$\large\text{COMBINE the LIKE TERMS}$

$\large\boxed{\mathsf{= (3x^3 - x^3 - 2x^3) + (-3y^3) + (x - 5x - x)}}$

$\large\boxed{\mathsf{= 3x^3 - x^3 - 2x^3 - 3y^3 + x - 5x - x}}$

$\large\boxed{\mathsf{= -3y^3 - 5x}}$

$\huge\boxed{\rm{Therefore, your \ answer \ is: -3y^3 - 5x}}$ $\huge\checkmark$

What is the distance between the points (4,-2) and )-5,3)?

abruzzese [7]

Answer:

10.3

Step-by-step explanation:

Let the given points be the endpoints of a right triangle. The horizontal change in x is from 4 to -5 and is negative 9; the vertical change in y is from -2 to+ 3 and is +5.

The desired distance is found using the Pythagorean theorem:

d = √(9² + 5²) = √106, or 10.3 (to the nearest tength)

14. The maximum capacity for seating in a theater is 500 people. The theater sells two types of

Eva8 [605]

Taking into account the definition of a system of linear equations, the amount of adult tickets sold is 356 and the amount of child tickets sold is 144.

<h3>System of linear equations</h3>

A system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.

Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied. That is to say, the values of the unknowns must be sought, with which when replacing, they must give the solution proposed in both equations.

<h3>Amount of ticket sold</h3>

In this case, a system of linear equations must be proposed taking into account that:

"x" is the amount of adult tickets sold.
"y" is the amount of child tickets sold.

The maximum capacity for seating in a theater is 500 people. If they sold out on a certain showtime, this is represented by x+y=500.

On the other side, the theater sells two types of tickets, adult tickets for $7.25 each and child tickets for $4 each and the made a total of $3,157. This is represented by 7.25x +4y=3157.

So, the system of equations to be solved is

$\left \{ {{x+y=500} \atop {7.25x+4y=3157}} \right.$

There are several methods to solve a system of equations, it is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.

In this case, isolating the variable x from the first equation you get:

x=500 - y

Substituting this expression in the second equation you get:

7.25× (500 -y) +4y=3157

7.25×500 - 7.25y +4y=3157

3625 - 7.25y +4y=3157

- 7.25y +4y=3157 -3625

-3.25y= -468

y= (-468)÷ (-3.25)

Substituting this value in the expression x=500 - y you get:

x=500 - 144

Remembering that "x" is the amount of adult tickets sold and "y" is the amount of child tickets sold, you get that the amount of adult tickets sold is 356 and the amount of child tickets sold is 144.

60 PTS WILL MARK BRAINLIEST IF CORRECT {see image} Write a rule for the function whose graph can be obtained from the given pare

disa [49]

Answer:

y = -1/2 | x+3|

Step-by-step explanation:

y = f(x + C) C > 0 moves it left

C < 0 moves it right

y = Cf(x) C > 1 stretches it in the y-direction

0 < C < 1 compresses it

y = −f(x) Reflects it about x-axis

Our parent function is

f(x) = |x|

We want it 3 units left

y = f(x + 3)

y = |x+3|

Then reflected across the x axis

y = −f(x)

y = -|x+3|

Then shrink by 1/2 vertically

y = Cf(x)

y = -1/2 | x+3|

Does 21.6,28.8,36 equal a right triangle

Alex_Xolod [135]

21.6 < 28.8 < 36

<span>if they are the lengths of the sides of a right triangle then:

$21.6^2+28.8^2=36^2\\\\L_s=466.56+829.44=1296\\\\R_s=1296\\\\L_s=R_s$

therefore it's the right triangle.</span>
