Answer:
6xy
Step-by-step explanation:
(0.75 * 3.5a) + (0.75 * -6b) = 2.63a -4.5b
Since there are 43560 feet in an acre, 285 feet is 0.654% of an acre.
Hope this helps!
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
