Given the system of linear equations. Choose all of the options that could be used to solve the system using addition

myrzilka [38]

<h2>Hello!</h2>

The answer is:

The only operations that could be used to solve the system using addition are the first and the third operation.

To solve the problem, we need to check and discard each of the given option to see if the operations works to solve the system using addition, so, trying the given options.

The system of equation is:

$x+y=7\\12x+y=5$

We can see that the only way to solve the system using addition, is multiplying the first or the second equation by -1, so, we can eliminate the variable "y", let's prove that:

- First operation: Multiplying<u> the first equation</u> by -1 and add the equations together,

$x+y=7\\12x+y=5$

$x*(-1)+y*(-1)=7*(-1)\\12x+y=5$

$-x+-y=-7\\12x+y=5$

Adding the equations, we have:

$12x-x+y-y=5-7$

$11x+=5-7$

$11x+=-2$

$x=-\frac{2}{11}$

We can see that we can solve the problem using the first operation the operation.

- Third operation: Multiplying <u>the second equation</u> by -1 and add the equations together,

$x+y=7\\12x+y=5$

$x+y=7\\12x*(-1)+y*(-1)=5*(-1)$

$x+y=7\\-12x+-y=-5$

Adding the equations we have:

$-12x+x+y-y=-5+7$

$-11x=2$

$x=-\frac{2}{11}$

We can see that we can solve the problem using the third operation.

Also, we can see that in both equations the variable "y" has the same coefficient, the only operations that could work to solve the system using addition are the first and the third operation.

Have a nice day!

What theory best explains the moon’s origin?

Sholpan [36]

Answer:

The giant-impact theory.

Explanation:

The giant-impact theory proposes that the Moon formed in a collision between the Earth another smaller celestial body. It is estimated that the smaller planet was roughly about the size of Mars. The debris from the resulting impact, over time, collected to form a mass that is now, presumably, the Moon.
