3y^2 and -3/4y^2
5x and 2/3x
12x^2
D. 311 divided by 12 = 25.91
The nearest tenth would be 25.9
Y= ax² -4x +3
-b/2a is x - coordinate of the vertex,
line of symmetry x=-2, x=-2 is a coordinate of the vertex also, because the line symmetry has vertex.
x= -b/2a
x= -2, b= -4
-2=-(-4)/2a
-2=4/2a
-2=2/a
a=2/(-2)=-1
a= - 1
