The form (x - p)^2 = q is the form that completing the square will leave us with.
---Add 5 to both sides
x^2 - 8x = 5
---Divide the b term by 2, and square it. Then, add that number to both sides.
-8/2 = -4
(-4)^2 = 16
x^2 - 8x + 16 = 5 + 16
x^2 - 8x + 16 = 21
---Factor!
(x - 4)^2 = 21
p = 4
q = 21
Hope this helps!! :)
Answer: 9 bookcases
Step-by-step explanation:
943 / 22 = 42.9 = 43 shelves
The number of books that are on the third shelf of the last bookcase is 43/5 = 8.6 = 9 bookcases
There are nine bookcases on the third self.
An equation can't be perpendicular to a line, but the <u>graph</u> of the equation can.
When that happens, we recall that the slopes of perpendicular lines are negative reciprocals.
One line is the graph of [ <span>y = 2x + 13 ]. The slope of the line is 2 .
So the slope of a line perpendicular to it must be -1/2 .
The equation of a line perpendicular to it is: <u>y = (-1/2 x) plus (any number)</u>.
The y-intercept of the perpendicular line doesn't matter. Only its slope does.

Y is 6 and x is 2 I have shown my work in the picture pls ask any questions
I think it might be D but I’m not 100% sure, I would wait for someone else to answer lol
