<h3>
Answer: Choice C. (-x, -y)</h3>
Explanation:
Focus on one point, such as A = (1,2). Note how it moves to point A ' = (-1, -2). Both x and y coordinates have been flipped from positive to negative. The rule therefore is 
. This describes a 180 degree rotation (either clockwise or counterclockwise, it doesn't matter). Points B and C follow the same idea.
Side note: Lines AA', BB' and CC' all go through the origin (0,0).
Step-by-step explanation:
Given points
( x1 , y1 ) = ( 0, 4)
And
( x2 , y2 ) = ( - 4 , - 3 )
Now
Slope(m)
= ( y2 - y1 ) / ( x2 - x1 )
= ( - 3 - 4) / ( -4 - 0)
= - 7 / - 4
= 7/4
Answer:
Technically, one (they equal the same thing) but 2 in this case.
Step-by-step explanation:
6 + 6 + 4
6 + 4 + 6
Solution:
Vertical angles are a pair of opposite angles formed by intersecting lines. re vertical angles. Vertical angles are always congruent.
These two angles (140° and 40°) are Supplementary Angles because they add up to 180°:
Notice that together they make a straight angle.
Hence,
From the image
The following pairs form vertical angles
Hence,
One pair of the vertical angles is ∠1 and ∠3
Part B:
Two angles are said to be supplementary when they ad together to give 180°
Hence,
From the image,
The following pairs are supplementary angles
Hence,
One pair of supplementary angles is ∠5 and ∠6
Answer:
64
Step-by-step explanation:
The common difference is 80 / (8 - 3)
= 16
So f(18) - f(14) = (18 - 14) * 16
= 54
