Step-by-step explanation:
The equation of a parabola that relates it focus is

So here, we isolate x^2.


Next, we factor out 4.

Our p=8 so this tells us the distance of the vertex to the focus.
Answer: no solution
Step-by-step explanation:
7x + 5 + 5x = 15x - 7 - 3x + 2
12x + 5 = 12x - 5
-12x -5. -12x -5
0 = -10
no solution
Answer:
x = 29
Step-by-step explanation:
Added together equals to 180 degrees. Write out the equation:
x + 35 + 4x = 180
5x + 35 = 180 (Add the x together)
5x = 145 (Minus both sides by 35)
x = 29
