Answer:
See description below.
Step-by-step explanation:
An inequality is an equation with more than one solution and they use <, >, or . There are a number of ways to work with inequalities.
Solving: To solve inequalities in one variable, treat it just like an equation. Solve using inverse operations. If you divide or multiply by a -1 then be sure to flip the sign. For example, if you have > then it becomes <.
Graphing on a number line: To graph inequalities in one variable, use a number line. Plot a point on the number line with an open circle then an arrow pointing toward the solution set. If you have an equal to, you would shade in the open circle.
Solving: To solve inequalities in two variables, you need a system meaning more than one. You solve it like a system of equations by graphing.
Graphing: To graph inequalities with two variables, graph each in y=mx+b form using the y-intercept and slope. Connect the points with a dashed line unless equal to. Equal to inequalities have a solid line. To show the solution set, shade the side of the inequality which (x,y) points make it true. To find this, test a point by substituting into the inequalities.
Answer:
x = 12 is the excluded value
Step-by-step explanation:
An excluded value is the value/s of x that make the denominator of the rational function equal to zero as this would make the function undefined.
Equate the denominator to zero and solve for x
6x - 72 = 0 ⇒ 6x = 72 ⇒ x = 12 ← excluded value
Answer:
a) , b) , c) , d) , e) , f) .
Step-by-step explanation:
a) Sea la distancia vertical con respecto al nivel del mar. Asúmase como positiva la distancia vertical por encima del nivel del mar. Entonces, la forma matemática equvalente es .
b) Sea el año con respecto al momento cuando nace el Cristo. Asúmase como positivo el año posterior al año del nacimiento del Cristo. Entonces, la forma matemática equivalente es .
c) Sea el balance de cuenta. Asúmase como positiva la acreencia de dinero. La acreencia es lo opuesto de la deuda. Entonces, la forma matemática equivalente es .
d) Sea el tiempo con respecto al instante de referencia y esperado de un evento. Asúmase como positivo el retraso. El retraso es lo opuesto del adelanto. Entonces, la forma matemática equivalente es .
e) Sea la temperatura con respecto al punto de referencia o de "temperatura cero". Asúmase como positiva toda temperatura mayor que ese punto de referencia. Entonces, la forma matemática equivalente es .
f) Sea la distancia vertical con respecto al nivel del mar. Asúmase como positiva la distancia vertical por encima del nivel del mar. Entonces, la forma matemática equvalente es .
