3/5 i believe. if you take 7 and divide it by 2 its 3.5.
1/2 = 0.5...to turn to a percent, multiply by 100.
0.5 x 100 = 50%
The answer is, x-5 equals to 0. So x equals to 5. So your answer is 5.

To find the y intercept you must substitute 0 into x.
F(x) = (-3x0) - (6x0) - 5
F(x) = -5
To find the axis of symmetry and vertex we use the formula -b/2a to find the x coordinate
x = 6/(-3x2)
x = 6/-6
x = -1
Now we need to find the y coordinate so we sub -1 into x.
F(x) = (-3x-1) - (6x-1) - 5
F(x) = 3 + 6 - 5
F(x) = 4
The axis of symmetry and vertex are (-1,4) and the y coordinate is -5. Hope this helps.
