2.) Helen is considering two different moving services. Service A charges a $15 monthly fee for unlimited streaming of movies and $2.50 per DVD rental. Service B charges a $12 monthly fee for unlimited streaming of movies and $3.50 per DVD rental. The system of equations below describes the relationship between the number of DVDs rented per month (x) and the monthly cost (y), in dollars for both services.
y = 15.00 + 2.50x AND y = 12.00 + 3.50x Which statement about the costs of the movie services is true?
A. When Helen rents fewer than 3 DVD's per month, service A will cost less per month than service B will cost.
B. When Helen rents more than 3 DVDs per month, service B will $12 more per month than service A will cost.
C. When Helen rents 3 DVDs per month, either service will cost her $22.50 per month. D. When Helen rents 6 DVDs per month, either service will cost her $27.00 per month.
Answers
Answer:
C. When Helen rents 3 DVDs per month, either service will cost her $22.50 per month.
Step-by-step explanation:
y = 15.00 + 2.50x
y = 12.00 + 3.50x
When x = 2
y = 15.00 + 2.50x
= 15.00 + 2.50(2)
= 15.00 + 5.00
= 20.000
y = 12.00 + 3.50x
= 12.00 + 3.50(2)
= 12.00 + 7.00
= 20.00
When x= 4
y = 15.00 + 2.50x
=15.00 + 2.50(4)
= 15.00 + 10.00
= 25.00
y = 12.00 + 3.50x
= 12.00 + 3.50(4)
= 12.00 + 14.00
=26.00
When x = 3
y = 15.00 + 2.50x
= 15.00 + 2.50(3)
= 15.00 + 7.50
= 22.50
y = 12.00 + 3.50x
= 12.00 + 3.50(3)
= 12.00 + 10.50
= 22.50
When x = 6
y = 15.00 + 2.50x
= 15.00 + 2.50(6)
= 15.00 + 15.00
= 30.00
y = 12.00 + 3.50x
= 12.00 + 3.50(6)
=12.00 + 21.00
= 33.00
The correct answer:
C. When Helen rents 3 DVDs per month, either service will cost her $22.50 per month.

Answers
Answer:
Puesto que [tex]AB\neq BC\neq AC[/tex], entonces se trata de un triángulo escaleno.
Step-by-step explanation:
Procedemos a graficar el triángulo agregando los puntos y los lados correspondientes. Incluimos la construcción en la imagen adjunta abajo.
A continuación, calculamos los lados del triángulo a través del Teorema de Pitágoras:
AB
[tex]AB = \sqrt{(9-6)^{2}+[7-(-3)]^{2}}[/tex]
[tex]AB = \sqrt{109}[/tex]
BC
[tex]BC = \sqrt{(3-9)^{2}+(4-7)^{2}}[/tex]
[tex]BC = \sqrt{45}[/tex]
AC
[tex]AC = \sqrt{(3-6)^{2}+[4-(-3)]^{2}}[/tex]
[tex]AC = \sqrt{58}[/tex]
Puesto que [tex]AB\neq BC\neq AC[/tex], entonces se trata de un triángulo escaleno.

A theater rents their space for $650 per night.
The renters are willing to contribute $200 but need
to make the rest in ticket sales. If the renters
charge $8 per ticket, then what is the least number
of tickets that must be sold in order to make a
profit?
Answers
Answer:
57 tickets
Step-by-step explanation:
This is because 650-200= 450 and 450/8 is 56.25
so round the answer up and you get 57
Answer:
(exact 56.25) rounded, more realistic 57 tickets
Step-by-step explanation:
650 total
650-200=450 this is the price removing the 200 as the starting investment.
450÷8 = 56.25 people would need to buy movie tickets.
since there can not be 0.25 of a ticket then, a rounded 57 people would have to buy tickets and they would have 456$
they only need 450 (56.25×8) so they have an extra 6 dollars to buy KitKats and candy or something.

Answer:
f(x) = (x -6)(x +2)
Step-by-step explanation:
The graph shows the x-intercepts are -2 and +6. The factors will be binomials such that these values make the factors zero: (x +2) and (x -6).
f(x) = (x -6)(x +2)

HELP ASAP PLEASE, APPARENTLY MY ANSWER IS WRONG
Answers
Answer:
[-5,-13]
Step-by-step explanation:
To solve this, start by getting rid of the -1 by adding 1 to 8 now you're left with:
|x - 4| ≤ 9 now you will solve this like a regular absolute value inequality
Because the equation withing the absolute value signs can be negative, you will solve this equation twice, once with a negative answer, and the next time, with a positive answer. However, in order to get a negative answer the sign ≤ needs to be flipped. Now we can solve.
Equation 1:
x - 4 ≤ 9 add 4 to -4 so it cancels out, then add it to 9
x ≤ 13
Equation 2:
x - 4 ≥ -9 add 4 to -4 so it cancels out, then add it to -9
x ≥ -5
Both of these equations can be simplified and turned into one compound inequality:
-5 ≤ x ≤ 13
In interval notation, this would be written as:
[-5,13]
