x^2 - y^2 - 2y - 1
x^2 - (y+1)^2
Answer:
5 is your answer
Step-by-step explanation:
The 
will equal to 5, because 
= 25
The point through which the same line is passing will be (9,13) so option (C) will be correct.
<h3>What is a line segment?</h3>
A line section that can connect two places is referred to as a segment.
A line segment is just part of a big line that is straight and going unlimited in both directions.
The line is here! It extends endlessly in both directions and has no beginning or conclusion.
The equation of any line with slope m can be given as
y = mx + c
Given,
slope m = 1/2
Point of passing (-7, 5)
So,
5 = -7/2 + c ⇒ c = 17/2
So the equation will be,
y = x/2 + 17/2
2y = x + 17
Now checking all points (9,13) is satisfying.
2(13) = 9 + 17
26 = 26
Hence point (9,13) is passing through the line.

Answer:
The correct option is C
Step-by-step explanation:
if f(x)= x3 + x2 - 20x
Replace f(x) by y
y = x3 + x2 - 20x
0 =x3 + x2 - 20x
x3 + x2 - 20x = 0
Take out x as a common:
x(x2+x-20)=0
Find factors of x2+x+20.
x(x^2+4x-5x-20) = 0
x{x(x+4)-5(x+4)}=0
x(x+4)(x-5)=0
Set x= 0
x=0 , x+4=0 , x-5 =0
x=0, x=0-4 , x=0+5
x=0, x= -4, x=5
x=(0,5,-4)
The correct option is C....
First let’s call the square shape A and the rectangle shape B.
To find the area of shape A you do 24 x 24 = 576cm squared
To find the area of shape B you do 40 x 24 = 960cm squared
To find the total area you just add the two areas together
576 + 960 = 1536cm squared
