90+31= 121
3x-1+121=120
3x+120=180
-120
3x=60
Divide by 3 on both sides
X=20
Answer:
The answer is "This direct variant (-4,2) is part of it".
Step-by-step explanation:
The equation expresses its direct variation relation
Where x and y vary directly, and k vary continuously.
Now so the point (4,-2) is in the direct relation of variation, so from equation (1) we are given,
The equation (1) is therefore converted into
Then only the point (-4,2) satisfies the connection with the four possibilities (2). Therefore (-4,2) is a direct variant of this.
Since the square is on a quadrant plane and it is a square, the fact that the lines cross in the center and start and stop in the corners allows you to tell that they are perpendicular.
So answer one is (B, D) 2 is (0, C) 3 is: 1
