Answer:
get x isolated
Step-by-step explanation:
Well, we see that it is a straight line
so the derivitive would be perpendicular
5/4 times what=-1
-4/5
the slope is -4/5
Answer:
x = -8
Step-by-step explanation:
Given the equation:

Note that

then

Rewrite the equation as

then

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.
