Y = 2x - 4....so sub in 2x - 4 for x in the other equation
y = x^2 - 6x + 12
2x - 4 = x^2 - 6x + 12
x^2 - 6x - 2x + 12 + 4 = 0
x^2 - 8x + 16 = 0
(x - 4)(x - 4) = 0
x - 4 = 0
x = 4
x - 4 = 0
x = 4
solution is (4,4)
Answer:
282/17
Step-by-step explanation:
6+3/34 =207/34
and 207/34+21/2=282/17
Answer:
Step-by-step explanation:
General form of the linear differential equation can be written as:

For this case, we can rewrite the equation as:

Here 
To find the solution (y(x)), we can use the integration factor method:

Then 
So, we can find:

Suppose that
, then
, and we find:

To check our solution is right or not, put your y(x) back to the ODE:



(it means your solution is right)
The quadratic formula is:

and

Let's identify our a, b, and c values:
a: -1
b: 1
c: 12
Plug in the values for a, b, and c into the equation. Let's do the first equation:

Simplify everything in the radical:

Simplify the radical:

Combine like terms:

Simplify:

This is one solution, now, let's solve for the other equation:
Since when simplified, everything is the same except the subtraction sign, we can skip the simplification again and change the sign to subtraction:

Combine like terms:

Simplify:

Your final answers are:


(2-3)/(-1-4)
-1/-5
the answer is A
hope this helps!
