Points ), K and L are collinear with J between L and K. IF KJ = 28 - 3, LK = 9x + 7 and LJ = 4x - 8,
babymother [125]

J, K, and L are collinear

J is between K and L

LK = KJ + LJ

LK = 9x + 7

KJ = 2x - 3

LJ = 4x - 8

9x + 7 = (2x - 3) + (4x - 8)

9x + 7 = (2x + 4x) + (-3 - 8)

9x + 7 = 6x + -11

9x + 7 = 6x - 11

9x + 7 - 7 = 6x - 11 - 7

9x = 6x - 18

9x - 6x = 6x - 6x - 18

3x = -18

x = -6

∴ The value of x is -6

Solve the given system of equations using any method and then choose the correct ordered pair from the given choices:
Mnenie [13.5K]

Answer:

c

Step-by-step explanation:

Given the 2 equations

x + y = 3 → (1)

3x - y = 1 → (2)

Adding the 2 equations term by term will eliminate the term in y

4x = 4 ( divide both sides by 4)

x = 1

Substitute x = 1 into either of the 2 equations and evaluate for y

Substituting into (1)

1 + y = 3 ( subtract 1 from both sides )

y = 2

Solution is (1, 2 ) → c
