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.
It is just two as you are dividing a negative by and negative turns into a positive
-7-1/2-5 because to solve, you do y2-y1/x2-x1
So you get -6/-3, which equals 2
SLOPE IS 2
Answer:
x=4
Step-by-step explanation:
19+3x=3(x-5)
do rainbows
19+3x=3x-15
subtract 19 on other side
3x=3x+4
divide out the 3s
x=4
Answer:
1/3n-3<6
Step-by-step explanation:
One third of a number: 1/3
3 is subtracted from 1/3 of a number n: 1/3n -3
Result is less than 6: less is represented with the symbol <. So, the result of the expression 1/3n-3 is less (<) than 6.
The final expression:
1/3n-3<6
