Answer:

The equation formed would be y=6y+5.

Step-by-step explanation:

By substituting the equation for x into the equation for y, we would get y=3(2y+3)-4, and after distributing, that equation is y=6y+9-4. We can simplify this and get the answer y=6y+5.

If x2 + mx + m is a perfect-square trinomial, which equation must be true?
noname [10]
<h2>Hello!</h2>

The answer is:

The third option,

x^{2}+mx+m=(x+2)^{2}

<h2>Why?</h2>

We are looking for an equation that establishes a relationship between the perfect-square trinomial and the givens notable products.

So, we are looking for a notable product that gives us a value of "m" that is the coefficient of the linear term (x) and it's also the constant term.

- Trying with the two first options, we have:

(x+1)^{2}=x^{2}+2x+ 1\\\\(x-1)^{2}=x^{2}-2x+ 1

We can see that for these first two options, the value of m has not the same value for the coefficient of the linear term and the constant term since m is equal 2 and the constant number is not 2.

- Trying with the third option, we have:

(x+2)^{2}=x^{2}+2*(2*x)+2^{2}=x^{2} +4x+4

Now, we can see that the value of m is the same for the coefficient of the linear term and the constant term, we can see that m is equal to 4.

So, the correct option is the third option, because

m=4

x^{2} +mx+m=(x+2)^{2}=x^{2} +4x+4=x^{2} +mx+m

Have a nice day!
