Example 2

Arada [10]

Answer:

y=x-2

Step-by-step explanation:

If you have drawn the graph of $y = x^2 - 3x + 1$ .

To determine the equation of the line which should be drawn to solve the equation: x² - 4x +3=0

Simply carry out the subtraction: $x^2 - 3x + 1 -(x^2 - 4x +3)$

$\implies x^2 -3x + 1-x^2 + 4x -3 \\= x^2 - x^2+ 4x - 3x-3 + 1\\=x-2$

The equation of the line which should be drawn is: y=x-2

What this means is simply:

$y = x^2 - 3x + 1$ and $y=x-2,$ then:\\x^2 - 3x + 1=x-2\\x^2 - 3x + 1-x+2=0\\x^2 - 4x + 3=0$

Kendra used these steps to solve the equation 2x + 5 = 3 + 2(x + 1). Which choice describes the meaning of her result, 5 = 5?

11Alexandr11 [23.1K]

Hello!

We can solve this algebraically

2x + 5 = 3 + 2(x+1)

Distribute the 2

2x + 5 = 3 + 2x + 2

combine like terms

2x + 5 = 2x + 5

Since both sides of the equation is the same all values of x make the equation true

The answer is A

Hope this helps!
