Answer:
C
Step-by-step explanation:
3x + 3y = -x + 5y
3x + x = 5y - 3y
4x = 2y
Divide both by 2
2x = y
(1,2) when x=1, y=2
2(1)=2 is a true statement
(2,4) when x=2, y=4
2(2)=4 is a true statement
Answer:
False.

Step-by-step explanation:
In 8 hours 30m Corner earns $80.75
In how many hours Zoey earns $118.75
Hours Zoey works= 510*118.75/80.75(converted 8hours into minutes by multiplying with 60)
Solving we get 12 hours 30m.
Answer:
○ sin 15° = sin 30°⁄2 = ±√[1 - cos 30°\2]
Step-by-step explanation:
According to the Sine Half-Angle Identity, this is the formula:
sin x = sin ˣ⁄2 = ±√[1 - cos x\2]
Notice the <em>-</em><em>cos</em><em> </em><em>x</em><em>\</em><em>2</em><em> </em>inside the radical. The second option nearly resembles this option. It has a positive symbol inside. Do not let this confuse you. The Cosine Half-Angle Identity is the formula that has a positive in the radical:
cos x = cos ˣ⁄2 = ±√[1 + cos 30°\2]
