Answer:
A is the answer...........
Explanation
8x+3=3x+8
8x-3x=8-3
5x=5
x=5/5
x=1
Answer:
15
Step-by-step explanation:
Just insert 3 wherever the z is at.
5 * (6 - 3)
5 * 3
= 15
B: a reflection across the x-axis followed by a translation 4 units right.
Comparing the points to their mapped images compares A to E, B to F, C to G, and D to H. In each point, the y-coordinate switches signs and the x-coordinate is subtracted by 4.
Reflections across the x-axis will switch the sign of the y-coordinate, and reflections across the y-axis will switch the sign of the x-coordinate. Since the y-coordinates are the ones whose sign changed, the points must have been reflected across the x-axis.
Translations to the left will cause the x-coordinate to increase, and translations to the right will case the x-coordinate to decrease. Since the x-coordinate of every point was subtracted, this means that the translation must have been to the right.
Answer:
<em>28 ; 76 ; 38</em>
Step-by-step explanation:
<em>KL</em> =
=
= <em>28</em> units
<em>YZ</em> = 2 × JK = 38 × 2 = <em>76</em> units
<em>LZ</em> = 76/2 = <em>38</em> units
