What is -x+y=6 in funtion form
lisov135 [29]
To get the function form, the y must be the only variable on one side. So, we need to solve for it.

We have:

-x + y = 6

then we get

y = 6 + x

when we move the x to the other side to get y by itself.

If you have any questions then leave a comment. Good luck!

Answer:

  • = 2x + (4 \times 36) - (4 \times x)
  • = 2x + 144 - 4x
  • = (2x - 4x) + 144
  • =  - 2x + 144
  • =  - 2(  x  - 72)

Can someone please help with #16
ollegr [7]

Answer:

∠ WZX = 50°

XW is not an altitude.

Step-by-step explanation:

16. See the attached figure.

XW is the angle bisector of ∠ YXZ, hence, ∠ WXY = ∠ WXZ

Now, given that ∠ YXZ = 8x + 34 and ∠ WXY = 10x - 13

Hence, ∠ YXZ = 2 ∠ WXY

⇒ 8x + 34 = 2(10x - 13)

⇒ 8x + 34 = 20x - 26

⇒ 12x = 60

⇒ x = 5.

Hence, ∠ XZY = ∠ WZX = 10x = 50° (Answer)

Now, ∠ WXZ = ∠ WXY = 10x - 13 = 37°

Hence, from Δ WXZ,

∠ WZX + ∠ WXZ + ∠ XWZ = 180°

⇒ 50° + 37° + ∠ XWZ = 180°

⇒ ∠ XWZ = 93° ≠ 90°

Hence, XW is not an altitude. (Answer)
