Answer:

y=(1/4)*x

Step-by-step explanation:

to inverse set f(x)=4x

as y=4x

next, change places y and x

4y=x

now, solve for y

4y=x

y=(1/4)*x

Answer:

The inverse is 1/4x

Step-by-step explanation:

f(x) = 4x

y = 4x

Exchange x and y

x = 4y

Solve for y

Divide each side by 4

1/4x = 4y/4

1/4x = y

The inverse is 1/4x

Switch the variable x and y with each other. Then the correct option is B.

<h3>What is inverse of a function?</h3>

Let the function will be

f: X → Y

Then the inverse function will be

f⁻¹: Y → X

The function is given below.

f(x) = 3x – 10

Then the inverse function of the f(x) will be

Put y in place of f(x).

    x = 3y – 10

  3y = x + 10

    y = (x + 10) / 3

Switch the variable x and y with each other.

Then the correct option is B.

#12 Find the value of x.<br> #13 Find the value of the variable. <br><br> PLEASE HELP
bixtya [17]

Answer:

  12.  x = 5

  13.  z = 2√21

Step-by-step explanation:

For any given pair of intersecting secants, the product of the distances to the near and far circle intersections is a constant. When those intersection points are both the same (as for a tangent), the same is still true: the product is the square of the length of the tangent segment.

12. (x-2)((x-2) +(x+4)) = 4(4+5)

  (x -2)(2x +2) = 36

  x^2 -x -2 = 18 . . . . . . . divide by 2 and eliminate parentheses

  (x -5)(x +4) = 0 . . . . . . subtract 18 and factor

  x = 5 . . . . . . . . . . . . . . by the zero product rule, the only solution with x > 2

___

13. 6(6+8) = z^2

  z = √84 . . . . . . . . take the square root

  z = 2√21 . . . . . . . simplify

Two numbers differ by 5. Seven times the smaller plus four times the larger is 108. Find the number
ladessa [460]

Answer:

<h3>8 and 13</h3>

Step-by-step explanation:

Let the two numbers be x and y

If the two numbers differs by 5, then;

y-x = 5 ...1

x is the smaller

y is the larger

If seven times the smaller plus four times the larger is 108, this is expressed as;

7x + 4y = 108 ... 2

From 1;

y = 5 + x .... 3

Substitute 3 into 2;

From 2;

7x + 4y = 108

7x + 4(5+x) = 108

7x + 20 + 4x = 108

11x + 20 = 108

11x = 108-20

11x = 88

x = 88/11

x = 8

Since y = 5+x

y = 5 + 8

y = 13

hence the numbers are 8 and 13
