Answer:

d:5

Step-by-step explanation:

isolate the y in second equation

x=y+6

substitute back into first equation

(y+6)+y=4

combine like terms

2y+6=4

subtract 6 from both sides

2y=-2

divide both sides by 2

y=-1

then plug y into either equation, ill use the first one

x+(-1)=4 and then solve by subtracting -1 and you get 5

Rewrite the following quadratic functions in intercept or factored form. Show your work.
Dmitry [639]

<u>Answer: </u>

f(x) = 3(x+2)(x-2)

<u>Step-by-step explanation: </u>

We are given the following the quadratic function and we are to rewrite it in intercept or factored form:

f(x) = 3x^2 - 12

We can factorize the given function so taking the common factors out of it to get:

f(x)=3x^2 - 12

f(x) = 3 (x^2 - 4)

The term (x^2-4) is in the form a^2-b^2 so it can further be factorized to give:

f(x) = 3 (x+2)(x-2)

Therefore, the factored form of the given quadratic function is f(x) = 3(x+2)(x-2).
