The awnser is A becuase 12/3=4
Answer:
mark as brainliest!!!!!!
Step-by-step explanation:
22+13=-4a+3a
35= -a is ur answer
Step-by-step explanation:
nobody knows!!
The vertex is at (0, 3) so y=a(x-0)²+3, which is y=ax²+3
next, use a given point to find a: 10=a(3)²+3, so 9a=7, a=7/9
the equation is then y=
![\frac{7}{9}x^2+3](https://tex.z-dn.net/?f=%20%5Cfrac%7B7%7D%7B9%7Dx%5E2%2B3%20)
as for the first question, the shape is an ellipse, the domain is -5≤x≤5, the range is -3≤y≤3
the equation can be written as :
