Answer:
x=√-1/3 y^2 +3 or x=-√-1/3 y^2 +3
Step-by-step explanation:
Let's solve for x.
3x2+y2=9
Step 1: Add -y^2 to both sides.
3x2+y2+−y2=9+−y2
3x2=−y2+9
Step 2: Divide both sides by 3.
3x^2/3= -y^2+9/3
x^2=-1/3 y^2 +3
x=√-1/3 y^2 +3 or x=-√-1/3 y^2 +3

Answer:
Alex baked 9 cherry pies
Step-by-step explanation:
apple : blueberry : cherry = 1:4:3
apple + blueberry + cherry = 24
1 part: 24 / ( 1+4+3) = 24 / 8 = 3
** Cherry has 3 parts: 3 x 3 = 9
check: apple = 3 x 1 = 3
blueberry: 3 x 4 = 12
12 + 3 + 9 = 24
