Subtract 2.2 from both sides leaving -2n on the left and 10 on the right. from there you want to get "n" by itself so you divide both sides by -2n and you get n=-5

2.2-2n=12.2
-2.2 -2.2

-2n = 10
/-2 /-2

n=-5

Please help :(<br> will mark brainliest and give 100 points
nikdorinn [45]

The equation is non linear because it doesn’t have a constant rate of change.

The table represents a non linear function, as the x values increase the y values increase at different rates.

Hi i need help asap my parent taught me how to do this equation (x^2-4x)^2+7x^2-28x+12=0 but i still dont understand I really ne
artcher [175]

Answer:

x = 1,  x = 2,  x = 3

Step-by-step explanation:

Hello, please consider the following.

(x^2-4x)^2+7x^2-28x+12=0 \\\\(x(x-4))^2+7x(x-4)+12=0\\\\\text{Let's note }X = x(x-4)\text{ the equation becomes}\\\\X^2+7X+12=0\\\\\text{The sum of the zeroes is -7=-3+(-4) and the product is 12=(-4)*(-3).}\\\\\text{Wo we can factorise.}\\\\X^2+7X+12=X^2+4X+3X+12=X(X+4)+3(X+4)=(X+4)(X+3)=0\\\\X=-4 \ \ or \ \ X=-3

So we need to solve:

x(x-4)=-4 \ \ or \ \ x(x-4)=-3\\\\ x^2-4x-4=(x-2)^2=0 \ \ or \ \ x^2-4x+3=(x-1)(x-3)=0

So, the solutions are x = 2, x = 1, x = 3

Thank you
