<span>Formula : V + F – E = 2
where V = number if vertices, F = number of faces and E = number of edges
<u>Question a:</u>
V + F - E = 2
V = 2 - F + E
V = 2 - 12 + 18
V = 8
(a) </span><span>12 faces, 18 edges, <u>8</u> vertices
<u>Question b:</u>
</span>V + F - E = 2
<span>E = V+ F - 2
E = 14 + 8 - 2
E = 20
(b) </span><span>8 faces, <u>20</u> edges, 14 vertices</span>
The vertex form of the quadratic function:
(h, k) - vertex
We have
h = 3, k = 4
Therefore your answer is:
<h3>C. (3, 4)</h3>
Answer:
(6x-1)(3x-2)
Step-by-step explanation:
18x²-15x+2 = 18x²-12x-3x+2= 6x(3x-2)-1(3x-2)=(6x-1)(3x-2)
Answer:
B. 3x -2y = 10
Step-by-step explanation:
The given line rises three units for each two units of run to the right. Hence its slope is 3/2. A parallel line will also have a slope of 3/2.
Of the equations we can see, selection B has a slope of 3/2. It can be rewritten in slope-intercept form as ...
3x -10 = 2y . . . . . add 2y-10 to isolate the y-term; next divide by 2.
y = 3/2x -5 . . . . . the coefficient of x is the slope
