Answer:

f^(-1)(x) = -3x/(3x-3)

Step-by-step explanation:

1) replace f(x) by y

● y = 3x/(5x+3)

2) exchange x and y

● y = 3x/(5x+3)

● x = 3y / (3y +3)

3) solve for y

● x = 3y / (3y +3)

● x (3y +3) = 3y

● 3xy + 3x = 3y

● 3xy - 3y = -3x

● y (3x - 3) = -3x

● y = -3x /(3x-3)

4) replace y with f^(-1)(x)

● y = -3x/(3x-3)

● f^(-1)(x) = -3x/(3x-3)

Step-by-step explanation: Interviewing 15 students out of 1,200 does not show an accurate result, as he should have interviewed more students. Also, just took the quiz.

Answer:

Here,

JM=MK

so,

7x+5 = 8x

[tex]7x + 5 = 8x \\ ⇒ 5 = 8x - 7x \\ ⇒5 = x[/tex]

. ° . JM = 7x+5 = 7×5+5 = 40

. ° . MK = 8x = 8×5 = 40

Hence,

Answer:

the answer to that question is 11/16

Using the probability principle, the probability of picking two tiles which sums above 7 is 11/16.

Recall :

The only way to choose two tiles which sums up to a number greater than 7 would be :

Since selection is performed with replacement ;

The probability of choosing two tiles whose sum is greater than 7 ;

Hence, probability of choosing tiles with a sum greater than 7 is 11/16

Therefore, the probability of picking two tiles which sums above 7 is 11/16.

Answer:

y = 4(x - 2)² + 48

Step-by-step explanation:

Given

y = 4x² - 16x + 64

Using the method of competing the square

Factor out 4 from 4x² - 16x

y = 4(x² - 4x) + 64

add/ subtract ( half the coefficient of the x- term)² to x² - 4x

y = 4(x² + 2(- 2)x + 4 - 4 ) + 64

   = 4(x - 2)² - 16 + 64

    = 4(x - 2)² + 48

y = 4(x - 2)² + 48

Answer:

5x + 6y = -10

Step-by-step explanation:

(-2, 0) and (-8, 5)

m = (y₂ - y₁) /  (x₂ - x₁)

m = (5 - 0) / (-8 -(-2)

m = 5 / (-8+2)

m = -5/6

y = mx + b

(-8, 5)

5 = -5/6(-8) + b

5 = 40/6 + b

b = 5 - 40/6

b = -5/3

y = mx + b

y = -5/6x - 5/3           *6

6y = -5x -5(2)

6y = -5x - 10

5x + 6y = -10

Answer:

Step-by-step explanation:

As seen from the first given equation: x + 1/x = 2

If we think of x as x/1 instead then we get:

x/1 + 1/x = 2.

To combine the fractions we multiply the top and bottom of the first one (x/1)  by x to get x^2/x so both have the same denominator so we can combine them which gives us:

(x^2+1)/x=2

Move x to the other side and we get:

x^2+1=2x

Move it back and we get a quadratic equation of

x^2 - 2x + 1

This factors into (x-1)(x-1) meaning x=1

For all the other equations they are equal because x=1.

1 to the power of anything is still one so each of the equations below will result in: 1+1/1 which is 2.

Therefore all of them are equal.

The answer is

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(4,2) and (7,6)

The midpoint is

[tex]M = ( \frac{4 + 7}{2} \: , \: \frac{2 + 6}{2} ) \\ = ( \frac{11}{2} \: , \: \frac{8}{2} )[/tex]

We have the final answer as

[tex]( \frac{11}{2} \: , \: 4)[/tex]

Answer:48

Step-by-step explanation:

If x = 1, then 3*1 = 3 which when modded with 5, we get 3 as a remainder. In other words, 3/5 = 0 remainder 3. We don't use the quotient at all when it comes to modular arithmetic. All we care about is the remainder.

If x = 2, then 3*2 = 6 which leads to remainder 1 when we divide by 5. Therefore, 3x = 1 (mod 5) when x = 2.

If x = 3, then 3*3 = 9 = 4 (mod 5) because 9/5 = 1 remainder 4.

So 3x = 4 (mod 5) when x = 3.

We don't need to check D since x = 3 is a solution and it's smaller than x = 4.

If you wanted to check x = 4, then 3*4 = 12 = 2 (mod 5) because 12/5 yields a remainder of 2.
