If b is the midpoint of ac, find bc (ab=3x-1 and ac=8x-20)

1 answer:

4 0

Bc would equal 26. Since ab and bc would equal the same thing, you would add (3x-1) to (3x-1) and equal it to (8x-20) and solve.

Tanzania [10]

Answer: -3 degrees

Step-by-step explanation:

Lets say that the original temperature was "x."

The temperature rose by 11 degrees so it is now at 11+x.

Then the temperature fell by 14 degrees so you subtract. 11+x-14

11-14= -3 so you subtract 3 degrees from the original temperature and there fore the relative temperature is -3

What is the value of the discriminant in the equation shown below?<br><br> x^2 -6x +4 =0

irakobra [83]

Answer:

Discriminant = 20

Step-by-step explanation:

We use formula to find the discriminant.

Discriminant (D) = b^2 - 4ac

The given equation is x^2 - 6x + 4 = 0.

Here the value of a = 1, b = -6 and c = 4.

Plug in the given values in the formula, we get

Discriminant (D) = (-6)^2 - 4*1*4

= 36 - 16

Discriminant = 20

Thank you.
