Answer: It is 3 and negative -3
Step-by-step explanation:3 units away from zero forwards and back are both 3 but one is negative
X = 2
<span>y = 3 </span>
<span>2 + 3 = 5 </span>
<span>2³ + 3² = 17 </span>
<span>------------------- </span>
<span>BUT: </span>
<span>x + y = 5 </span>
<span>x^y + y^ x = 17 </span>
<span>y = 5 - x</span>
Hmmm if you don't have a Unit Circle, this is a good time to get one, many you can find online. Anyhow, check your unit circle for cos(30°) and sin(30°).
