Dilations<br> If ABCD is dilated by a factor of Į, the<br> coordinate of D' would be
ValentinkaMS [17]

9514 1404 393

Answer:

  D'(2, -1)

Step-by-step explanation:

Dilation about the origin by factor k multiplies each coordinate by that factor:

  (x, y) ⇒ (kx, ky)

For k = 1/3, this is ...

  (x, y) ⇒ (x/3, y/3)

  D(6, -3) ⇒ D'(6/3, -3/3) = D'(2, -1)

Calculate JK if LJ=45, JM=60 and LM=75
aliina [53]

Answer:

JK = 20

Step-by-step explanation:

Angle Bisector Theorem: an angle bisector of a triangle divide the opposite side into two segments that are proportional to the other two sides of the triangle

LK / JK = LM / JM

(45 - JK) / JK = 75 / 60 = 5 / 4

5 JK = 4 (45 - JK)

5 JK = 180 - 4 JK

9 JK = 180

JK = 20

Anyone know this?????
rosijanka [135]

Answer:

(- 2, 1 ) and (1, 4 )

Step-by-step explanation:

Given the 2 equations

y = - x² + 5 → (1)

- x + y = 3 → (2)

Rearrange (2) expressing y in terms of x by adding x to both sides

y = x + 3 → (3)

Substitute y = x + 3 into (1)

x + 3 = - x² + 5 ( subtract - x² + 5 from both sides )

x² + x - 2 = 0 ← in standard form

(x + 2)(x - 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

x - 1 = 0 ⇒ x = 1

Substitute these values into (3) for corresponding values of y

x = - 2 : y = - 2 + 3 = 1 ⇒ (- 2, 1 )

x = 1 : y = 1 + 3 = 4 ⇒ (1, 4 )
