  • 2. Rotate the triangle 90º clockwise about the origin and then translate it 10 units left and 9 units down.

Step-by-step explanation:

  • <em>Easy way to take one of the vertices and apply the transformations</em>

1. Rotate the triangle 90º counterclockwise about the origin and then translate it 10 units left and 9 units down.

  • False

2. Rotate the triangle 90º clockwise about the origin and then translate it 10 units left and 9 units down.

  • True
  • (-3, 3) →  (3, 3) → (3 - 10, 3 - 9) = (-7, -6)

3. Rotate the triangle 90º counterclockwise about the origin then translate it 1 unit up.

  • False

4. Rotate the triangle 90º clockwise about the origin then translate it 1 unit up.

  • False

Find midpoint of PQ with endpoints P (0,2) and Q (6,-2)
agasfer [191]

Answer:

(3, 0)

Step-by-step explanation:

The easiest way to do this problem is to average the x-coordinates and y-coordinates.

So,  (0 + 6) / 2 = 6/2 = 3 = x   and (2 - 2)/2 = 0/2 = 0 = y

Therefore, the midpoint is (3,0)

HURRY!!! 20POINTS!!! PLEASE!!!<br>If y=3/4 when x=1/2, find y when x=3
musickatia [10]
If y = 0.75 when x = 0.5, set up a proportion -

0.75:0.5
x:3

Since you have to multiply 0.5 by 6 to get 3, multiply 0.75 by 6 to get your answer: y = 4.5 when x = 3.

The graph represents a cubic function. Write the function.
Norma-Jean [14]

Zeros are

  • (0,0)
  • (-3,0)
  • (-4,0)

Write in factor form and solve

  • (x-0)(x-(-3))(x-(-4))=0
  • x(x+3)(x+4)=0
  • x[x(x+4)+3(x+4)]=0
  • x(x²+4x+3x+12)=0
  • x(x²+7x+12)=0
  • x³+7x²+12x=0

Points given (-2,16)

Solve for n

  • n(x³+7x²+12x)=y

On solving we get

  • n=-4

So the function is

  • y=-4(x³+7x²+12x)
  • y=-4x³-28x²-48x
