Answer:
1.8?
Step-by-step explanation:
V is at (-1,-1)
by reflecting it across the y axis its x coordinate gets inverted:
V'=(-1*-1,-1)=(1,-1)
so the second option is the correct one
Answer:
The midpoint of the segment with endpoints at the midpoints of s1 and s2 is (4,5).
Step-by-step explanation:
Midpoint of a segment:
The coordinates of the midpoint of a segment are the mean of the coordinates of the endpoints of the segment.
Midpoint of s1:
Using the endpoints given in the exercise.
Thus:
Midpoint of s2:
Thus:
Find the midpoint of the segment with endpoints at the midpoints of s1 and s2.
Now the midpoint of the segment with endpoints and . So
The midpoint of the segment with endpoints at the midpoints of s1 and s2 is (4,5).
Answer:
26, 30
Step-by-step explanation:
If you subtract from the sum the excess of the second over the first, you have a sum that is twice the first.
first number = (56 -4)/2 = 26
The second number is 4 more, so is ...
second number = 26 +4 = 30
_____
Check
Their total is 26 +30 = 56, as required.
