Pls Help Ill Give Brainlist

lesya692 [45]

Answer:

$(\frac{1}{2}, - \frac{1}{2} )$

Step-by-step explanation:

The properties of circumcenter give that it lies at the midpoint of the hypotenuse if it is of a right triangle.

Now, the given triangle is a right triangle and the two ends of the hypotenuse WU are U(-3,2) and W(4,-3).

Therefore, the mid point of the hypotenuse WU will be given by $(\frac{-3 + 4}{2}, \frac{2 - 3}{2}) = (\frac{1}{2}, - \frac{1}{2} )$ .

Therefore, the circumcenter of the right triangle Δ UVW will be $(\frac{1}{2}, - \frac{1}{2} )$ . (Answer)

4. 1 less than twice the square of a number

givi [52]

Answer:

2(x^2)-1

Step-by-step explanation:

The square of a number is just the number squared. We don't know what the number is so I will just say it is x. So we have 2 times x^2. Then we have to minus 1 from that. So 2(x^2)-1.

Hope this helps! :D

Solve this quadratic equation. 6x^2 - 2x = 7

sweet-ann [11.9K]

The solutions to the equation are $\frac{1 +/- \sqrt{43}}{6}$ .

You can find the answer to any quadratic by using the quadratic formula. The formula is below.

$\frac{-b +/- \sqrt{b^{2}-4ac}}{2a}$

Then find a (the number attached to x^2), b (the number attached to x) and c (the constant). This will allow you to plug in and solve.

$\frac{2 +/- \sqrt{-2^{2}-4(6)(-7)}}{2(6)}$

$\frac{2 +/- \sqrt{4 + 168}}{12}$

$\frac{2 +/- \sqrt{172}}{12}$

$\frac{1 +/- \sqrt{43}}{6}$
