Answer:
Green graph: y = 5x + 2
Red Graph: y = 3x + 3
Blue graph: y = 2x + 3
Step-by-step explanation:
21. In a parallelogram, opposite angles are equal and adjacent angles are supplementary (add to 180°).
m∠R = m∠P = 180° -m∠Q
m∠Q = 107°
m∠P = 73°
25. If you draw any diagonal, it divides the figure into two congruent triangles (by the SSS postulate). Corresponding angles are congruent, so the diagonal is a transversal between parallel lines. Thus opposite sides are parallel and the figure is a parallelogram.
27. Opposite sides are equal, and the diagonals bisect each other. Your four equations are
2w+4 = 5w-6 . . . . w = 10/3
12 = 3x-3 . . . . . . . x = 5
6y = 4y+6 . . . . . . . y = 3
27 = (5/4)z +2 . . . z = 20
Answer:
IV: colour of the room
DV: The number of minutes each group spends studying
Step-by-step explanation:
IV(Independent Variable) : is what is changed in the experiment and the colour of the room is being changed.
DV(Dependent Variable) : is what is measured in the experiment and the number of minutes in spent on studying is measured.
