Answer:
The number he thought of was 13
Step-by-step explanation:
Revers the problem
3.5 * 3 = 10.5
10.5 - 4 = 6.5
6.5 * 2 = 13
Answer: OPTION C.
Step-by-step explanation:
1. To solve this problem you must apply the Pythagorean Theorem, which is shown below:

Where a is the hypotenuse, and b and c are the legs of the triangle.
2. When you solve for one of the legs and substitute values, you obtain that the result is:

Answer:
(-1,-4)
Step-by-step explanation:
Because it is a rotation that turns both the x and y values the two swap places. The x value become negative because before it was in quadrant 4 where there was still a positive chance but rotating the point clockwise puts it into the third quadrant where there are only negatives.
Answer:
b.obtuse
Step-by-step explanation:
if it is obtuse it has 1 angle over 90° and two angles under 90°
The inequality will be 0 < x < 5 .
Each line plotted on a coordinate graph divides the graph (or plane) into two half‐planes. Before graphing a linear inequality, you must first find or use the equation of the line to make a boundary line.
The y z - plane is represented by the equation x = 0 .
As the region is between the y z - plane and the vertical plane x = 5 , we will get the inequality 0 < x < 5 .
Therefore , the inequality will be 0 < x < 5 .
