Answer:
Step-by-step explanation:
x²+y² = 5²
3²+y² = 25
y² = 16
y = ±√16 = ±4
Since the terminal side is in quadrant IV, y = -4
sinθ = -4/5
She isn't correct. 43 is a 2-digit odd number but it isn't composite. It's a prime number.
Answer:
2,3,6
Step-by-step explanation:
Answer:
y = -2x -2
x + 2y = 2
2x + y = -2 } x1
x + 2y = 2 } x2
2x + y = -2 } we eliminate 2x
2x + 4y = 4 } same signs subtract and different add respectively
-3y = -6
-3 -3
y = 2 (x , 2) we reserve
2x + (2) = -2 we take on the first equation and replace 2 on a coordinate for y
2x = -2 - 2
2x = -4
2 2
x = -2 (-2,2)
x y
Answer:
x = 
Step-by-step explanation:
= 5 ( multiply both sides by x to clear the fraction )
1 = 5x ( divide both sides by 5 )
= x
