Can you guys please help me. i don’t need the explanation i just need the answer
Fittoniya [83]

Answer:

36

Step-by-step explanation:

AOB + BOC = AOC

AOC = 90 since  the lines are perpendicular

6x-12 + 3x+30 = 90

Combine like terms

9x + 18 = 90

Subtract 18 from each side

9x+18-18 = 90-18

9x = 72

divide by 9

9x/9 = 72/9

x = 8

AOB = 6x - 12

         = 6*8 - 12

          = 48 -12

        = 36

Which phrase best descubes the translation from the graph y = (x - 5)2 + 7 to the graph of y = (x + 1)2 - 2?
Ber [7]

Answer:

"6 units left and 9 units down"

Step-by-step explanation:

Suppose a function is given in this form:

y=(x-a)^2+b

This is the parent function y = x^2

  • translated a units right (left if there was a + before a)
  • translated b units up (down if there was a - before b)

Now, to go from  y=(x-5)^2+7  to  y= (x+1)^2-2 , we can see that:

  • first function is 5 units right and 2nd one is 1 unit left, so there is a horizontal translation of 6 units left
  • first function is 7 units above and 2nd one is 2 units down, so there is a vertical translation of 9 units down

Thus, "6 units left and 9 units down" is the transformation(translation).

For what value of w is4w = 2w - 8
Talja [164]

Answer:

w =-4

Step-by-step explanation:

4w = 2w - 8

Subtract 2w from each side

4w-2w = 2w-2w - 8

2w = -8

Divide by 2

2w/2 = -8/2

w = -4
