Answer:
Step-by-step explanation:
Let x^3 = y
f(x) = 27(x^3)^2 + 1524(x^3) + 125
f(x) = 27 y^2 + 1524y + 125
You can now put this into the quadratic formula. When you do, you get
(y + 0.0821)(y+56.3623) = 0
So now you substitute x^3 into this
(x^3 + 0.0821)(x^3 + 56.3623)
x^3 + 0.0821 = 0
x^3 = - 0.0821
cuberoot x^3 = cube root 0.0821
x = - 0.4346
x^3 = - 56.3623
x = - 3.8341

Answer with explanation:
To draw the graph of linear equation of the form
y-a=m (x-b)
We will first write it in slope intercept form which is of the form

It will cut x axis and y axis at ,
respectively.
As Euclid postulate States that, Unique equation of line can be Determined by two points,So join these two points.And Infinite number of points lie on a line.
Graph B
I think it’s b to be honest with you
Answer:
Se vendieron 81 boletos de niños y 63 boletos de adultos.
Step-by-step explanation:
La cantidad de boletos vendidos es igual a:
(1)
En donde <em>a </em>es por adultos y <em>n</em> por niños
A su vez, el dinero gastado equivale:
(2)
Resolviendo la ecuación (1) para <em>a:</em>
(3)
Introduciendo (3) en la ecuación (2) tenemos:


Ahora podemos calcular el numero de boletos de adultos vendidos introduciendo <em>n</em> en la ecuación (3):

Entonces, se vendieron 81 boletos de niños y 63 boletos de adultos.
