Which equation is the inverse of 2(x - 2)2 = 8(7 + y)?

The inverse of an equation is the opposite of the equation

The inverse of the function is y =2 \pm  \sqrt{28 + 4x

<h3>How to determine the inverse of the function </h3>

The equation is given as:

2(x - 2)^2 = 8(7 + y)

Divide both sides of the equation by 2

(x - 2)^2 = 4(7 + y)

Open the bracket

(x - 2)^2 = 28 + 4y

Take the square roots of both sides

x - 2 = \pm\sqrt{28 + 4y

Add 2 to both sides

x =2 \pm  \sqrt{28 + 4y

Swap the occurrences of x and y

y =2 \pm  \sqrt{28 + 4x

Hence, the inverse of the function is y =2 \pm  \sqrt{28 + 4x

Find the value of the variable if P is between J &amp; K. <br><br> JP = 2x ; PK = 7x ; JK = 27
Nana76 [90]
J ---- P --- K

JP = 2x
PK = 7x
JK = 27

2x + 7x = 27
9x = 27
x = 27/9
x = 3

The value of P is 3.

JP = 2x = 2(3) = 6
PK = 7x = 7(3) = 21

If l parallel m find the value of x and y​
Katarina [22]

Answer:

14. x = 16; y = 23

15. x = 9; y = 13

Step-by-step explanation:

14. (4x + 4) = (7x - 44) (alternate exterior angles are congruent)

4x + 4 = 7x - 44

Collect like terms

4x - 7x = -4 - 44

-3x = -48

Divide both sides by -3

x = -48/-3

x = 16

39° + (8y - 43)° = 180° (consecutive exterior angles are supplementary)

39 + 8y - 43 = 180

Add like terms

-4 + 8y = 180

Add 4 to both sides

8y = 180 + 4

8y = 184

Divide both sides by 8

y = 184/8

y = 23

15. (15x - 26)° = (12x + 1)° (alternate exterior angles are congruent)

15x - 26 = 12x + 1

Collect like terms

15x - 12x = 26 + 1

3x = 27

Divide both sides by 3

x = 27/3

x = 9

28° + (12x + 1)° + (4y - 9)° = 180° (sum of interior angles of ∆)

Plug in the value of x

28 + 12(9) + 1 + 4y - 9 = 180

28 + 108 + 1 + 4y - 9 = 180

Add like terms

128 + 4y = 180

Subtract 128 from each side of the equation

4y = 180 - 128

4y = 52

Divide both sides by 4

y = 52/4

y = 13
