Answer:
A
Step-by-step explanation:
Since you are multiplying -2 and 12, you can put them in any order as long as you get - 24/5
1 carton has 36 eggs.
to find X eggs you would need to multiply 36 eggs by the number of cartons bought.
Let c = number of cartons:
The expression becomes: x = 36c
For 180 eggs, replace x with 180 and solve for c:
180 = 36c
c = 180 / 36
c= 5 cartons.
Answers:
- Vertex form: y = -2(x-1)^2 + 8
- Standard form: y = -2x^2 + 4x + 6
Pick whichever form you prefer.
=============================================================
Explanation:
The vertex is the highest point in this case, which is located at (1,8).
In general, the vertex is (h,k). So we have h = 1 and k = 8.
One root of this parabola is (-1,0). So we'll plug x = -1 and y = 0 in as well. As an alternative, you can go for (x,y) = (3,0) instead.
Plug those four values mentioned into the equation below. Solve for 'a'.
y = a(x-h)^2 + k
0 = a(-1-1)^2+8
0 = a(-2)^2+8
0 = 4a+8
4a+8 = 0
4a = -8
a = -8/4
a = -2
The vertex form of this parabola is y = -2(x-1)^2+8
Expanding that out gets us the following
y = -2(x-1)^2+8
y = -2(x^2-2x+1)+8
y = -2x^2+4x-2+8
y = -2x^2+4x+6 .... equation in standard form
Answer:
True
Step-by-step explanation:
a triangle can be formed with any side of any length
So we start off with what 4 numbers added together equal 32.
first truck 5 tons
second truck 7 tons
third truck 9 tons
and fourth truck 11.
5+7= 12 +9 = 21+11= 32.
