Rhett is solving the quadratic equation 0= x2 – 2x – 3 using the quadratic formula. Which shows the correct substitution of the
lesya692 [45]

Answer:

The correct option is 1.

Step-by-step explanation:

If a quadratic equation is defined as

ax^2+bx+c=0

then the quadratic formula is

x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}

The given equation is

0=x^2-2x-3

Here, a=1, b=-2 and c=-3.

Substitute these values in the above formula.

x=\frac{-(-2)\pm \sqrt{(-2)^2-4(1)(-3)}}{2(1)}

x=\frac{2\pm \sqrt{(-2)^2-4(1)(-3)}}{2(1)}

Therefore, the correct option is 1.

4. Hightop Roofing was $3765 in the "red" (owed creditors this amount) at the end of
gulaghasi [49]

The negative sign shows that they still owed $5000 to the creditors which shows a loss of money between June and December.

Step-by-step explanation:

Amount owed at the end of June = $3765

Amount owed at the end of December = $8765

As Hightop Roofing owed creditors the amount, therefore, we will consider the amount as negative, therefore,

Amount in June = -3765

Amount in December = -8765

To see the difference, we will subtract the amount owed in June from the amount owed in December.

Difference=(-8765)-(-3765)\\Difference=-8765+3765\\Difference=-5000

The negative sign shows that they still owed $5000 to the creditors which shows a loss of money between June and December.
