Alguien me ayuda a desplegar -9x+3=5 por favor

Answer:

x=-\frac{2}{9}

Step-by-step explanation:

Supongo que te refieres a ''despejar'' la variable.

-9x+3=5

Primero, aisla los terminos independientes en la derecha y los que tienen variables, en la izquierda. En este caso, el 3 es independiente y no está en la derecha. Para poder moverlo, debo hacer la operación contraria. Por ejemplo, está siendo sumado, para ponerlo del otro lado, lo voy a restar.

-9x+3-3=5-3

Resuelvo;

-9x=2

Ahora, tengo un -9 multiplicándome la variable x, para poder deshacer esta multiplicación y dejar la variable sola, debo hacer la operación contraria; es decir, dividir por -9.

\frac{-9x}{-9}=\frac{2}{-9}

Resuelvo;

x=-\frac{2}{9}

Y, si ya no se puede seguir, este sería mi resultado.

Para comprobar si es correcto, reemplazo en la ecuación original por el valor que ya he encontrado y las respuestas deben ser iguales.

-9x+3=5\\-9(-\frac{2}{9})+3=5\\ 2+3=5\\5=5

Breathing is cyclic and a full respiratory cycle from the beginning of inhalation to the end of exhalation takes about 7 s. the
eduard
In this problem, volume is computed:

volume = ∫(flow rate)·dt 

.. = ∫[0, t] (3/10)*sin(2πt/7)·dt

= (3 / 10)*(7 /(2 π))*(-cos (2 π t/7)+1) 

= (-21 / (20 π))*(cos (2 π t /7) - 1)

Volume is equal to 21 sin^2 (pit/7) / 10pi is the inhaled air in the lungs at time t

What are decimal places you better explain it throughly I am having much trouble I will give you 20 points or maybe even 100
Andrej [43]
Decimal places are the spaces present after a decimal, denoted by the . in a number. This means, if I had 1.2 the 2 is in the first decimal place. In 3.1415 , the 5 is in the 4th decimal place. It is also commonly called, in respective order, the tenths place, the hundreds place, the thousandths place, and so on. For example, in 1.432 the 4 is in the tenths place, the 3 is in the hundredths place, and the 2 is in the thousandths place.
