The standard form of a quadratic equation is Ax^2 + Bx + C = 0. So for –6 = x^2 + 4x – 1 to be in its standard form, we can move -6 to the other side of the equation and have x^2 + 4x + (-1 +6) = 0 x^2 + 4x + 5 = 0 So, from the standard form, the value of of C is 5<span>.</span>

Lauren says that -3.5 is greater than -3 1/3. Do you agree? Explain.

Answer:

$-3\frac{1}{2}$

Step-by-step explanation:

-3.5 means -(3 + $\frac{1}{2}$ )

In other words, -3.5 = $-3\frac{1}{2}$

When we draw two numbers $-3\frac{1}{3}$ and $-3\frac{1}{2}$ on a number line, $-3\frac{1}{2}$ comes first from left to right.

We know that all the numbers on a number line from left to right are in increasing order.

Therefore, $-3\frac{1}{2}$ is smaller than $-3\frac{1}{3}$ .

$-3\frac{1}{2}$

Lauren is not correct.

Hi!

what you do is you move all the numbers on one side of the equal sign and the variable on the other side, when you move the numbers the switch signs

so it will look like

-2n=2-4

-2n=-2

drop the minus

2n = 2

n =1
