For this case we have the following complex fraction:
Using the double C method, we can rewrite the given fraction.
We have then:
Then, we must factor the quadratic expression into the denominator.
We have then:
Finally, we cancel similar terms.
We have then:
Answer:
the complex fraction simplified is:
B) y-1/(y-6)(y-2)
Answer:
i think its C but i could be wrong
Step-by-step explanation:
He overall had a 10% loss.
For every 5 feet, the scale drawing is 1 unit. So we divide the dimensions by 5 to get the dimensions of the scale drawing.
120/5 = 24
1:5 = x:120 There are 24 5's in 120 so the new ratio is 24:120
75/5 = 15
1:5 = x:75 There are 15 5's in 75 so the new ratio is 15:75
The dimensions of the scale drawing is 24 units by 15 units.
Answer:
- minimum value: 2
- axis of symmetry: x = -1
Step-by-step explanation:
A graphing calculator can answer this very quickly. The graph shows the minimum is 2, at x=-1. The axis of symmetry is the vertical line through that point so is x = -1.

The extreme value of the quadratic ax^2 +bx +c is found at x = -b/(2a). Your quadratic has a=6 and b=12, so the extreme value is located on the line of symmetry at ...
x = -12/(2·6)
x = -1 . . . . . . . . . . line of symmetry; x-coordinate of vertex
__
The leading coefficient of this even-degree polynomial is <em>positive</em>, so we know it opens <em>upward</em>. That means the vertex is a minimum.
The value of the function at the vertex is ...
f(-1) = 6(-1)^2 +12(-1) +8 = 6 -12 +8 = 2
The minimum value is 2.
