Answer:
A
Step-by-step explanation:
Given 2 secants from a point outside the circle.
Then the product of the external part and the entire secant of one secant is equal to the product of the external part and the entire secant of the other secant, that is
(x + 1)(x + 1 + 11) = (x + 4)(x + 4 + 1)
(x + 1)(x + 12) = (x + 4)(x + 5) ← expand both sides
x² + 13x + 12 = x² + 9x + 20 ← subtract x² + 9x from both sides
4x + 12 = 20 ( subtract 12 from both sides )
4x = 8 ( divide both sides by 4 )
x = 2 → A
(-1,1)
D0 means starting at the origin of Z in this case, so doing the same thing as always, multiply the scale factor -1/2 to the coordinate of Z giving you (-1,1) and this is the final answer because the origin is (0,0) so doesn’t change anything
Answer:
162
Step-by-step explanation:
The number with "1" digit starts with 101 then 110 and so on.
The answer is actually d lol the idiot above me was right
The formula for slope is y = mx + b
y is the y value, m is the slope, x is the x value, and b is the y intercept.
The equation given for line e is

Therefore the slope of line e is -9/2
Line f is parallel and parallel lines have the same slope.
So the slope is line f is -9/2.
The picture isn't that clear and I can't really tell if it's-9/2 or 9/2.
But whatever it is, the slope of line f is the same as the slope of line e because they are parallel.
Good luck!
