Answer:
C=0,10E+5
Step-by-step explanation:
La respuesta es que la expresión que indica el costo mensual "C" en función de la energía "E" consumida es:
C=0,10E+5
Esto teniendo en cuenta que se indica que hay una tarifa fija de $5 por mes y que a esto se debe sumar el resultado de multiplicar la energía consumida por el valor del kilowatt-hora.
solved by a system of equations in two variables.
Answer:
A familiar situation is: cost of books you pay for versus the quantity of books bought.
Cost of books ($) and quantity of books are directly proportionally related in the situation.
The graph will look like the graph in the attachment below.
A quantity (dependent variable) will change constantly in relation to another quantity (independent variable) if the relation is a proportional relationship.
A familiar situation for example can be the cost you pay for books will be directly proportional or dependent on the number of books you bought.
That is:
Number of books = independent variable
Cost ($) = dependent variable
A change in the number of books will cause a change in the cost you will pay for buying books.
This shows a direct proportional relationship between the two quantities.
On a straight line graph, the graph will be a proportional graph showing number of books on the x-axis against cost ($) you pay on the y-axis.
Therefore:
A familiar situation is: cost of books you pay for versus the quantity of books bought.
Cost of books ($) and quantity of books are directly proportionally related in the situation.

Answer:
x=40/33
Step-by-step explanation:
Let's solve your equation step-by-step.
25(4x−3)−2x=45−x
Step 1: Simplify both sides of the equation.
25(4x−3)−2x=45−x
(25)(4x)+(25)(−3)+−2x=45+−x(Distribute)
100x+−75+−2x=45+−x
(100x+−2x)+(−75)=−x+45(Combine Like Terms)
98x+−75=−x+45
98x−75=−x+45
Step 2: Add x to both sides.
98x−75+x=−x+45+x
99x−75=45
Step 3: Add 75 to both sides.
99x−75+75=45+75
99x=120
Step 4: Divide both sides by 99.
99x
