Answer:
It's the 2nd one 3y2-43y over 12y2
Step-by-step explanation:
First u do a common denominator u multiply on the first side by 6y on the second side by 4 then u solve it till u get 6y2-86y over 24y2 then simplify by dividing by 2
The solid shape is a cone and a half sphere. So the equation would be (cone volume) + (1/2 sphere volume):

If the volume of the cone is 270pi and the height of the cone is 10, then:

The radius of the object is 9 cm. Therefore, we can plug into the formula for the total volume:

The total volume is 513 pi cm^3
The simplified answer is: -28a - 13b
37+53=90 so 180-90=90
x=90
x= 180-(37+53)
x= 90 ✅
The slope/y-int form would be y=9/2x+2 you have to move the x value and whole number(y-int) to the other side which would make them negative and then divide by the -2 and there you go.
