Answer:
the third one and the one
Step-by-step explanation:
<span>An angle measuring (870n)° is in standard position.The value of n in which the terminal side falls along the positive portion of the y-axis would be 1. This is because the reference angle would fall on the second quadrant, which still denotes a positive portion of the y-axis.</span>
Answer:
x=2/5, y=11/5
or x=−1y = 2
Step-by-step explanation:
Substitute y=3x+1 in x2+y2=5 to obtain
x2+(3x+1)2=5 ⇒ 10x2+6x−4=0
Hence
5x2+3x−2=0 ⇒ 5x2+5x−2x−2=0 ⇒5x(x+1)−2(x+1)= 0 ⇒ (5x−2)(x+1)=0
Hence
either
x=2/5, y=3×2/5+1=11/5
or x=−1, y=3×(−1) +1 = −2
