Answer:
-1.5 (3n-2)
Step-by-step explanation:
Factor -1.5 out of -4.5n+3
In order to find the GCF of these two numbers we need to list all their factors and find the first common one so.
44: 1,2,4,11,22,44
110, 1,2,5,10,11,22,55,110
Since 22 is the highest number that both share and its common, that would be your answer. Answer: 22.
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:
EACH TIE COSTS 7.43
Step-by-step explanation:
If 13.35x13=173.55 then that means the ties total is 189.46 now devide that by 22 it equals 13.35
Answer:
38°
Step-by-step explanation:
The angle 1 is 63°
The angle 2 is the same of angle 1
so :
63°+79°=142°
then :
180° - 142° = 38°.
