Answer:

+ 6x^{2} and -10y^{2}

Step-by-step explanation:

3x^{2} + 5y^{2} {} + 3 {} + 4y^{2} + 6 = 9x^{2} - y^{2}+ 9

3x^{2} + 9y^{2} {} + 9 {}  = 9x^{2} -  y^{2}+ 9

+ 6x^{2}    -10y^{2}

3x^{2} + 9y^{2} + 6x^{2} + 9 - 10y^{2} = 9x^{2} - y^{2}+ 9

9x^{2} - y^{2}+ 9 = 9x^{2} - y^{2}+ 9

Helpp need this done ASAP
lorasvet [3.4K]
Number two is proportional just do Y over X y/x meaning divided all the y’s over the x’s so 25 divided by 5 30 divided by 6 35/7 40/8 they all equal 5 so it’s proportional
number three isn’t proportional when you do y/x they all come out differently so you do y2-y1 over x2-x1 16-4/4-2 16-4=12 4-2=2 then you divided 12/2 that equals 6 you do that again but with the next numbers but they don’t equal so it’s no equation no constant
