Answer:
12
Step-by-step explanation:
This triangle is a 3-4-5 Pythagorean Triple. 9 is 3*3, 15 is 5*3, so b is 4*3, which is 12. Alternatively, you could use the Pythagorean Theorem's converse, sqrt(15^2-9^2), and get 12.
This is correct. The x-axis and the y-axis cross each other under a 90 degree angle. This gives us 4 quadrants with different values. The first quadrant is the upper-right (+,+), the second quadrant is, going counter-clockwise, the upper left (-,+), the third quadrant is the lower left (-,-), and the last, fourth one is the lower right (-,+). Positive values on the x-axis are on the right side of the meeting point, and the negative values are on the other side. The positive values on the y-axis are on the upper part. So, if the point is first with two positive values, it means that it is in the 1st quadrant. Moving it across the x-axis would take it in the same position but down, in the 4th quadrant (-,+), and then reflecting it across the y-axis would move it in the same place but left, like in a mirror, and it would place it in the 4th quadrant with two negative values, or -x, -y like the statement.

Answer:
0.667x
Step-by-step explanation:
150% = x
100% = ?
=> 100% * x / 150% = 0.667x
