Hello,
(3+2i)*x=17+7i
==>x=(17+7i)/(3+2i)
==>x=(17+7i)(3-2i)/((3+2i)(3-2i))
==>x=(65-13i)/13
==>x=5-i
Answer:
-4/5.
Step-by-step explanation: You just need to do 4/5 times -1/1 and anything you multiply by one, the result is the number that was multiplied by 1. Since there is a negative in front of 1, the answer is -4/5.
Answer: D. (-2, -1)
Step-by-step explanation:
Here we do two reflections to the point (-1, 2).
First, we do a reflection over the line x = y. Remember that a reflection over a line keeps constant the distance between our point and the given line, so we have that for a pint (x, y), the reflection over the line y = x is:
Ry=x (x, y) = (y, x)
so for our point, we have:
Ry=x (-1, 2) = (2, -1)
Now we do a reflection over the y-axis, again, a reflection over a line keeps constant the distance between our point and the given line, so if we have a point (x,y) and we do a reflection over the y-axis, our new point will be:
Ry-axis (x,y) = (-x, y)
Then in our case:
Ry-axis (2, -1) = (-2, -1)
The correct option is D.
The answer to your question is 8, y=8
