Answer:
Step-by-step explanation:
You're given a coordinate in the form of (x, y) and you're also given the vertex in the form of (h, k). We will use those in the vertex form of the equation
and solve for a. Filling in:
which simplifies a bit to
and a bit more to
. Add 3 to both sides to get
-8 = 4a so
a = -2
The equation, then, is
She had 22 marbles and gave away, 4 to two people, so 4*2 = 8. 22-8=14. she has 14 marbles left.
If you put 145 divided by 8 the remainder on a calculator would come out as a decimal
