Answer:

  • C)  (x, y) ⇒ (-x, y)
  • D)  (x, y) ⇒ (x, y+4)

Step-by-step explanation:

ΔDEF is a reflection and translation of ΔABC.

You know it is a reflection because the corresponding vertices have opposite orientations: CCW vs. CW. You know it is a horizontal reflection because the line EF corresponding to vertical line BC is still vertical.

You know a vertical translation is involved because corresponding vertices are all offset vertically from each other by the same amount (4 units).

Find the slope and y-intercept of 5x-y=-5
trasher [3.6K]
Slope is 5
Y intercept is 5

Solve:
5x-y=-5
(Isolate Y by adding y to both sides to get it alone and adding 5 to both sides)
Y=5x+5
We know that slope (m) is w the X so in this case it is 5
And then to find the y intercept we substitute O for X.
Y=5(0)+5
Y=5

(PRECALC) I need help on this one plz ❤️❤️❤️ help a girl out & the favor will be returned
tia_tia [17]

Answer:

The coordinates of the P' point are (-17.3,-10).

Step-by-step explanation:

We can use the components of the vector from 0 to P point. We know that the diameter is 40 meters, so the magnitude of the vector will be 20 m.

Now, the angle from the negative x-direction to the vector is 210°-180° = 30°.

The x-component of the vector will be:

V_{x}=-Vcos(30)

V_{x}=-20cos(30)=-17.32\: m

It is negative because the component is in the negative x-direction.

The y-component of the vector will be:

V_{y}=-Vsin(30)

V_{y}=-20sin(30)=-10\: m

It is negative too because the component is in the negative y-direction.

Therefore, the coordinates of the P' point are P'(-17.3,-10)

I hope it helps you!
