Answer:
x = - 4
Step-by-step explanation:
Given
- x² - 8x - 16 = 0 ( multiply through by - 1 to clear the leading negative )
x² + 8x + 16 = 0 ← this is a perfect square
(x + 4)² = 0 ( take the square root of both sides )
x + 4 = 0 ( subtract 4 from both sides )
x = - 4
A + b phrase describe the variable expression y + 8
Answer:
(B)
Step-by-step explanation:
we know that standard equation of parabola y²= 4x or x² = 4y .
So option (B) is correct .
Hope it's helpful
The answer is D. you add the 3/5 to the other side to get 1. and then you divide one and 4x to get 1/4.
For this case we have that by definition, the slope of a line is given by:
Where:
and 
are two points through which the line passes.
According to the image we have:
Substituting we have:
Thus, the slope of the line is:
