Answer:
Step-by-step explanation:
The <em>sum</em> is the result from adding two or more numbers to each other.
-6 is the starting point on the number line.
4 is added to -6, so an arrow from -6 goes 4 units to the right of the number line.
The arrow stops at -2.
Answer:
-2
Step-by-step explanation:
So we want to find the value of:
Simply add:
Thus, drop the word SUM on -2.
Further notes:
To use the number line to solve, first start by placing your point on -6.
Since we are <em>adding</em> 4 to -6, we move to the right. Thus, move from -6 four spaces to the right.
If you do so correctly, you will end up at -2, the same answer we acquired previously.

Answer:
The correct option is;
Segment FE over 3 = Segment FH
Segment FI over 3 = Segment FG, and
Segment EI over 3 = Segment HG
ΔEFI ~ ΔHFG
Step-by-step explanation:
The given transformations are'
ΔEFI is dilated by a scale factor of 1/3 and then it is reflected over line a
By dilation, we have
FH = 1/3×FE
FG = 1/3×FI
HG = 1/3×EI
Also by reflection over a line, the relative positions of the y-coordinates of the points remain the same while the x coordinates changes sign such that an upright mirror image of the dilated triangle is formed
Therefore, since we have;
the same for both triangles, that is given the following relation;
FG/FH = (1/3×FI)/(1/3×FE) = FI/FE
Then, ΔEFI is similar to ΔHFG (triangle similarity requirement AAA)
Hence, the correct option is that the
Segment FE over 3 = Segment FH
Segment FI over 3 = Segment FG, and
Segment EI over 3 = Segment HG
ΔEFI ~ ΔHFG.
