How do you find the f(x) inverse using fractions?

Answers

for example.. 1) switch places of x and y. x=3y+1 x=3 y +1
2) try to solve for y. so multiply the denominator by x to get rid of it
3) after multiplying, ur left with xy+x=3 x y + x=3
4) that converts to 2xy= x y =3
5) get rid of 2x on left by placing it on the right
6) convert y to inverse function

Determine the equation of a circle having a diameter with endpoints at (12,-14) and(2,4)

Answers

Center of a circle is a midpoint of line connecting two endpoints so center is:
(12,-14) (2,4) we divide those two points by two
C(a,b)- center
C(a,b)=((12+2)/2),(-14+4)/2)=(7,-5)
Radius is the distance from the center to any point on the circle:
we take point (2,4)

A polynomial equation with rational coefficients has the roots 7 + *sqrt* 3 , 2 - *sqrt* 6. Find two additional roots. a. 7 - *sqrt* 3 , 2 + *sqrt* 6
b. 3 - *sqrt* 7 , 6 + *sqrt* 2
c. 7 + *sqrt* 3 , 2 - *sqrt* 6
d. 3 + *sqrt* 7 , 6 - *sqrt* 2

Answers

Answer:

option: A

Step-by-step explanation:

" if for a polynomial with rational coefficients has irrational roots then these irrational roots will always appear in pair " .

we are given that $7+√(3)$ and $2-√(6)$ are two roots of a polynomial equation with rational coefficients, then it's complex conjugate is also a root of this polynomial equation i.e. ' $7-√(3)$ ' and ' $2+√(6)$ ' are also roots of this polynomial equation.

Hence, option A is correct.

If the coefficients of a polynomial equation are rational, then the irrational roots have to come in conjugate pairs.
The conjugate of 7 +√ 3 is 7 - √ 3 and the conjugate of 2 - √ 6 is 2 + √ 6.
Answer:
A ) 7 - √ 3 , 2 + √ 6
