Tan 135 = -1
so rectangular coordinates are (-7 sqrt2, 7 sqrt2)
The zero for -2x+10x-16 is positive 2
Answer:
The answer is 11.1
Step-by-step explanation:
First you need to figure out what all of the possible combinations of the two dice being thrown then divide it by the number of faces on both dice and you get your probability.
Answer:
It's D
Step-by-step explanation:
I can't see the option D
But, A,B, and C are absolutely incorrect.
You can draw the area bounded by the unequality

in following way:
1. Draw a dashed line

with a slope

(a dashed, because all points from this line, for example when x=0, y=-2 do not belong to the area);
2. Define which part (under the line or over the line) is suitable by substituting values. For example, when x=0 and y=0 you obtain that

is a right unequality, that means that the point (0,0) is a solution and belongs to the area;
3. Shade that part of the plane to which point (0,0) belongs, you receive the area over the line (see image).
From the done steps you can see that only fourth statement is true.
