Answer:
Choice A
Step-by-step explanation:
Use the F. O. L. D method while solving
Consider the system of inequalities
1. Plot all lines that are determined by equalities (see attached diagram)
2. Determine which bounded part of the plane you should select:
means that you should take points with y-coordinates greater than or equal to 2 (top part of the coordinate plane that was formed by the red line);
means that you should take points with x-coordinates less than or equal to 6 (left part of the coordinate plane that was formed by the blue line);- for
you can check where the origin is placed. Since 
, the origin belongs to the needed part and you have to take the right part of the coordinate plane that was formed by green line. - for
you can check where the origin is placed. Since 
, the origin belongs to the needed part and you have to take the bottom part of the coordinate plane that was formed by orange line.
3. According to the previous explanations, the shaded region is as in A diagram.
Answer: correct choice is A.
The answer is x = 6
Explanation:
First, you must assume that 5x-10=20. Next, you add 10 to 20, which makes the equation 5x=30. Next, divide 30 by 5, which then makes the equation x=6. When you substitute 6 in the original equation, it works, because 5(6)-10 equals 20.

Explicación paso a paso:
Dado que :
Los mejores cargos por préstamos hipotecarios:
Interés mensual = 7%
Intereses pagados sobre capital de 100 pesos
Intereses pagados = principal * tasa de interés
Intereses pagados = 100 * 7%
Intereses pagados = 100 * 0.07
Intereses pagados = 7 pesos
De ahí que los intereses pagados por un préstamo de 100 pesos sean 7 pesos
