Answer:

Step-by-step explanation:

5x + 15 = 2x + 3

5x + 15 - 15 = 2x + 3 - 15

5x = 2x + 3 - 15

5x - 2x = 2x - 2x + 3 - 15

5x - 2x = 3 - 15

3x = 3 - 15

3x = -12  ( divide both sides by 3)

x= -4

What is the image of (1,0) after a counterclockwise rotation of 60 degrees?
Anestetic [448]

Answer:

\vec s = \left(\frac{1}{2},\frac{\sqrt{3}}{2}  \right)

Step-by-step explanation:

The coordinate has the following polar form:

\vec r = (1, 0^{\circ})

The image of the coordinate rotated counterclockwise 60° is:

\vec s = (1, 60^{\circ})

Its equivalent form in rectangular coordinates is:

\vec s = (1\cdot \cos 60^{\circ}, 1 \cdot \sin 60^{\circ})

\vec s = \left(\frac{1}{2},\frac{\sqrt{3}}{2}  \right)
