Which shows the correct substitution of the values a, b, and c from the equation 1 = –2x + 3x2 + 1 into the quadratic formula? Q

Tanzania [10]

First of all, you have to manipulate the equation into the standard

$ax^2+bx+c=0$

form. You can simplify the 1's on both sides and you have

$3x^2-2x=0$

This means that your coefficients are

$a=3,\quad b=-2,\quad c=0$

And since the solving formula is

$x_{1,2}=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}$

Plugging your values yields

$x_{1,2}=\dfrac{-(-2)\pm\sqrt{(-2)^2-4\cdot 3\cdot 0}}{2\cdot 3}$

H(4 1/2, -3 1/4) x (3 3/4, -1 3/4) what the midpoint of hx

shtirl [24]

Answer:

(3 7/8, 2 3/4)

Step-by-step explanation:

To find the midpoint, the formula is (x1-x2)/2 and (y1-y2)/2. So, in this case, our x1 is 4 1/2 and our x2 is -3 1/4. Subtract x2 from x1 and you will get 7 3/4. Then, divide by 2 to get 3 7/8. This is our x-coordinate.

Our y1 is 3 3/4 and our y2 is -1 3/4. Subtract y2 from y1 to get 5 1/2. Then divide by two to get 2 3/4. This is our y-coordinate.

Now we have our x and y coordinates.

(3 7/8, 2 3/4)
