Let be x = - 4; then, - 4 -4y = 4;
-4y = -8 ; y = 2;
An ordered pair that is a solution to the equation is (-4;2);
Answer:
I really can't show a tree diagram on here, So i will come back to this question if I figure out how to do that.
Step-by-step explanation:
Well the average would change from 85 to 85.4
Quadrant IV
For an angle in the fourth quadrant the point P has positive x coordinate and negative y coordinate. Therefore: In Quadrant IV, cos(θ) > 0, sin(θ) < 0 and tan(θ) < 0 (Cosine positive).
