Answer:
sin A = 0.69
Step-by-step explanation:
sin A = 20 / 29 = 0.69
Answer:
1) Reflection in the x-axis
A' = (-2, -3)
2) Rotation of 180° clockwise about the origin
A'' = (2, 3)
3) Translation of 3 units down and 4 units to the right
A''' = (6, 0)
Step-by-step explanation:
The transformations are as follows;
1) Reflection in the x-axis
Here the x-coordinate is the same and the y-coordinate changes sign.
Therefore, we have;
A (-2, 3)
After reflection in the x-axis becomes A' = (-2, -3)
2) Rotation of 180° clockwise about the origin
When, a point (x, y) is rotated 180° clockwise about the origin, it becomes (-x, -y)
Therefore, we have;
A' = (-2, -3) becomes A'' = (2, 3)
3) Translation of 3 units down and 4 units to the right
Translation of 3 units down and 4 units to the right = 
Which gives
A''' = (2 + 4, 3 - 3) = (6, 0).
Answer:

<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
-x - 2y = 2
4x - 2y = -8
<u>Step 2: Rewrite Systems</u>
-x - 2y = 2
- Multiply both sides by -1: x + 2y = -2
<u>Step 3: Redefine Systems</u>
x + 2y = -2
4x - 2y = -8
<u>Step 4: Solve for </u><em><u>x</u></em>
<em>Elimination</em>
- Combine equations: 5x = -10
- Divide 5 on both sides: x = -2
<u>Step 5: Solve for </u><em><u>y</u></em>
- Define equation: 4x - 2y = -8
- Substitute in <em>x</em>: 4(-2) - 2y = -8
- Multiply: -8 - 2y = -8
- Isolate <em>y</em> term: -2y = 0
- Isolate <em>y</em>: y = 0
