The following pairs of equations are equivalent. Describe the operation that occurred in the second equation. 3+9=12 and 3+9-5=1

elena55 [62]

Answer:

See explanation

Step-by-step explanation:

A. Given the equation

$3+9=12$

Using the subtraction property of equality (subtracting 5 from both sides of equation), we'll get an equivalent equation

$3+9-5=12-5$

B. Given the equation

$x-4=7$

Using the addtion property of equality (adding 4 to both sides of equation), we'll get an equivalent equation

$x-4+4=7+4$

C. Given the equation

$2(6)=12$

Using the division property of equality (dividing both sides of equation by 2), we'll get an equivalent equation

$\dfrac{2(6)}{2}=\dfrac{12}{2}$

D. Given the equation

$\dfrac{x}{2}=5$

Using the multiplication property of equality (multiplying both sides of equation by 2), we'll get an equivalent equation

$2\cdot \dfrac{x}{2}=2\cdot 5$

It is known that the function f(x)=3(1.5) ^x has an area of 48.787 units^2"over the interval 0 <=x<=5.If g(x)=f(x)-3, what

ch4aika [34]

We have

$\displaystyle \int_0^5 g(x)\; dx = \int_0^5 (f(x)-3)\; dx = \int_0^5 f(x)\; dx - \int_0^5 3\; dx$

The first integral is known and it is 48.787. The second integral is the area of a rectangle:

$\int_0^5 f(x)\; dx - \int_0^5 3\; dx = 48.787 - 15 = 33.787$
