I hope this helps you
5x+20=57
5x=57-20
5x=37
x=37/5
We have the following rule for exponents:

then, in this case we have:
4. 19
5. A. 105.7

Answer:
point "i" has coordinates (-x, y)
Step-by-step explanation:
Any point on the horizontal line containing point A will have the same y-coordinate. It appears that point "i" in the diagram is a point on the circle and on the horizontal line, so is the point you're looking for. Because the circle is centered at the origin, point "i" will have an x-coordinate that is the opposite of that of point A.
Point "i" is such a point. It has coordinates (-x, y).
