<em>Answer:</em>
<em>[-3,3]</em>
<em>Step-by-step explanation:</em>
<em>Write the problem as a mathematical expression.</em>
<em>4x^2+y^2=36</em>
<em>Subtract 4x^2 from both sides of the equation.</em>
<em>y^2=36-4x^2</em>
<em>Take the square root of both sides of the equation to eliminate the exponent on the left side.</em>
<em>y= + and - </em>
<em />
<em>The complete solution is the result of both the positive and negative portions of the solution.</em>
<em>y= </em>
<em />
<em />
<em />
<em>Set the radicand in </em>
<em> greater than or equal to 0 to find where the expression is defined.</em>
<em />
<em />
<em>So your answer would be [-3,3]</em>

Answer:
-85º
Step-by-step explanation:
275 - 360 = -85
4- 2/3 (4-1/6) divided by 3/4
parenthesis first
4 - 2/3 (3 5/6) divided by 3/4
change to an improper fraction (6*3+5)/6
4 - 2/3 ( 23/6)divided by 3/4
4 - 46/18 divide by3/4
copy dot flip
4 - 46/18 * 4/3
4 - 23/9 * 4/3
4 - 92/27
get a common denominator of 27
4*27/27 -92/27
108/27 - 92/27
16/27
