Answer:

8. \frac{4x}{x^{2} -1}

10. \frac{1-2xy}{3x^{2} }

Step-by-step explanation:

8. write all numerators above the least common denominator, that is going to look like x/x+1/x+1-2/4. next we calculate the difference on the third level of the fraction, where it is x+1-2. we end up getting x/x+1/x-1/4. now we need to simplfy the fraction. that will be 4x/(x+1)*(x-1). now we simplfy the product on the denominator so it is going to be 4x/x^2-1.

10. we reduce the fraction on the left with 2. that is going to turn the left side of the fraction from 2x/6x^3 into x/3x^3. now our expression is x/3x^2 - 4y/6x. now we simplify the expression into 1/3x^2 - 4y/6x. now we reduce the fraction on the right side with 2. that is going to turn 4y/6x into 2y/3x. now we have the expression 1/3x^2 - 2y/3x. we now write all numerators above the least common denominator 3x^2. that is going to then look like 1-2xy/3x^2 which is our answer.

Answer:  0.80

<u>Step-by-step explanation:</u>

P (2 ≤ x ≤ 4) is: P(X = 2) + P(X = 3) + P(X = 4)

                   =     0.36    +    0.12    +     0.32

                   =             0.48             +     0.32

                   =                            0.80

It can also be calculated as: 1 - P(X = 1)

                                           =  1 -  0.20

                                           =     0.80

Which of the following is an equation of the circle with its center at (0,0) that passes through (3,4) in the standard (x,y) coo
natka813 [3]

Answer: x² + y² = 25

Step-by-step explanation: As we have x²+y²=25 (A) as options,

                                                                x-y=1 (B)

                                                                x+y=25 (C)

                                                                x²+y²=5 (D)

We can rule out B and C as they are not circles. Circles must be

(x - xc)² + (y - yc)² = r². They must have index 2.

We have then A or D.

As the circle must pass through (3,4), we can substitute as x=3 and y=4

(A) 3² + 4² = 9 + 16 = 25 ok

(D) 3² + 4² = 9 + 16 = 25 ≠ 5

So, it is A, x² + y² = 25
