Answer:
c = 
f= 1500
Step-by-step explanation:
Tenemos la siguiente ecuación
Tenemos los siguientes valores para m=15000, c = 3000 y para m = 20000, c=3500. Es decir, tenemos las siguientes ecuaciones
Si restamos la segunda ecuación de la primera, tenemos que
Luego
Entonces 
Si tomamos la primera ecuación, tenemos que 
. Es decir,
Esta solución, al plantear 2 ecuaciones y dos incógnitas, plantea un sistema dos por dos.
Answer:
9:7.
Step-by-step explanation:
14 blue triangles and 18 yellow triangles,
The LCM of them both is 2 so we can divide both of the numbers by 2.
14 divided by 2 = 7
18 divided by 2 = 9
Since they asked for the ratio of <u><em>yellow triangles to blue triangles</em></u>,
The answer will be <em><u>9:7</u></em>.

The student is incorrect, the actual x-intercept is (5, 0).
<h3>Is the student correct or incorrect?</h3>
Here we have the equation:
x + 2y = 5
The student says that the x-intercept is the point (0, 5).
So if you look at the point you already can see that the student is incorrect, this is because the x-intercept always must have a y-value of 0. (the graph only intercepts the x-axis when y = 0).
So the point (0, 5) can't be an x-intercept.
For the given function:
x +2y = 5
The x-intercept is given by:
x + 2*0 = 5
x = 5
So it is (5 , 0).
