Answer:
D. 5x^2 + 2y^2 + 12x + 5y
Step-by-step explanation:
6x + 2y + y^2 + 6x + 2y + y^2 + 4x^2 + x^2 + y
6x + 6x = 12x
12x + 2y + y^2 + 2y + y^2 + 4x^2 + x^2 + y
2y + 2y + y = 5y
12x + 5y + y^2 + y^2 + 4x^2 + x^2
y^2 + y^2 = 2y^2
2y^2 + 4x^2 + x^2 + 12x + 5y
4x^2 + x^2 = 5x^2
2y^2 + 5x^2 + 12x + 5y
5x^2 + 2y^2 + 12x + 5y
Answer: The two equations are:
y = 5x + 40
y = 3x + 60
In each problem, you are given the cost per ride. That is the slope, it goes in front of the x.
Then, you are also given the entry fee. That is the y-intercept, it goes at the end of the equation.
Now, the equations are in slope intercept form. Y = MX + B
Graphing the equations will give an answer of (10, 90)
This means for both plans 10 rides will cost $90.
The answer would be D because 3h + 2 (water) has to be less than or equal to > 14

Answer:
Isadora necesitará un papel decorativo de 12.18m ^ 2
Step-by-step explanation:
La clave para resolver esta pregunta es conocer la forma de la habitación que Isadora quiere cubrir.
Mirando la medida en la pregunta, podemos deducir que la forma de la habitación que Isadora quiere cubrir es rectangular. Por lo tanto, para obtener los metros cuadrados de papel decorativo necesarios, lo que debemos hacer es calcular el área de la habitación rectangular.
Matemáticamente, el área de la habitación rectangular es = Espesor de la habitación × longitud de la habitación = 4.35 × 2.80 = 12.18 m ^ 2
