Answer:
(-3, 16)
Step-by-step explanation:
If it is reflected off the y - axis, the x coordinates change.
It becomes (-3, 16)
We have that 3 pencils cost $0.35, and 2 dozen pencils are 24 pencils, then we divide by 3 to know how many 3-pencils combo we can get:
therefore, 2 dozen pencils would cost $2.8
Answer:
the lat one should be the right answer
Step-by-step explanation:
Answer:
Step-by-step explanation:
Reference angle in quadrant I,
θ' = θ
Reference angle in quadrant II,
θ' = 180° - θ
Reference angle in quadrant III,
θ' = θ - 180°
Reference angle in quadrant IV,
θ' = 360° - θ
13). θ = 315°
Since, the given angle is in the 4th quadrant,
Reference angle θ' = 360° - 315°
= 45°
14). θ' = (620° - 540°)
= 80°
Reference angle = 80°
15). θ' = 630° - θ
= 630° - 580°
= 50°
Reference angle = 50°
