Answer:

(x, y) = (5, 2)

Step-by-step explanation:

Given:

LP = x

MP = 2y+3

NP = y+3

KP = 3x -8

KP = MP, LP = NP

Find:

x, y

Solution:

The given relations between the segment lengths let us write two equations:

KP = MP

3x -8 = 2y +3 ⇒ 3x -2y -11 = 0 [eq1]

LP = NP

x = y +3 ⇒ x -y -3 = 0 [eq2]

Subtracting 3 times [eq2] from [eq1] gives ...

(3x -2y -11) -3(x -y -3) = 0

y -2 = 0 . . . . . . . . simplify

y = 2 . . . . . . . . . . add 2

Substituting this value into [eq2] gives ...

x = 2 + 3 = 5

The values of x and y are ...

x = 5, y = 2

1) SHOW WORK: Evaluate f(-2):

babymother [125]

Answer:

- 10 and 60

Step-by-step explanation:

To evaluate f(- 2) substitute x = - 2 into f(x)

f(- 2) = (3 × - 2) - 4 = - 6 - 4 = - 10

To evaluate f(8) substitute x = 8 into f(x)

f(8) = 8² - 4 = 64 - 4 = 60
