Its line 1
if we expand the second and third expressions they come back to the first.
The last one is called the vertex form of a parabola
Answer:
See explanation, and ask for more details if unclear!
Step-by-step explanation:
The perfect square of this equation is
, since the square would be
. 1/4=4/16, meaning that you can set up the equation in the following way:


Take the square root of both sides:

Add 1/2 to both sides:

I think its D: Having a master’s degree and getting a doctorate degree
Answer:
B
Step-by-step explanation:
Solve the first half of the equation-
-8x+3 >/=27
-3 -3
-8x>/=24
divided by -8 on both sides
x</=-3
Now for the second side:
-13x+5>/= 57
-5 -5
-13x>/=52
divide by -13 in both sides
x</=-4
We now have two equations. The answer would be x</=-3 because -4 is also less than three, so it can be simplified down to -3. I know you might not have needed the explanation since it’s just khan academy, but I figured I’d explain it anyway :)
