Add like terms the answer will be 6a+b+c
2(-15)= -30 +22=-52-55=107 (I think)
Answer:
Well your answer will be 3 small boxes and 6 large boxes
Step-by-step explanation:
It says there is 3 more large boxes sent than small boxes so all together it can hold 450 books? then there were 6 large boxes = 300 giving 3 small boxes= 150 giving your total to 450

Answer:
y = -(x -3)^2 +2
Step-by-step explanation:
The vertex form of the equation for a parabola is ...
y = a(x -h)^2 +k
where the vertex is (h, k) and the value 'a' is a vertical scale factor.
The value of 'a' can be found by looking at the y-value of points ±1 either side of the vertex relative to the vertex. Here, the vertex y-value is +2 at x=3, and either side goes down 1 unit (to y=1) for 1 unit to the right or left. So, a = -1.
Using the values we've read from the graph for the vertex (h, k) = (3, 2) and the scale factor a = -1, we can write the equation as ...
y = -(x -3)^2 +2
X=(-b/2a)
that is the answer
