Step-by-step explanation:
For no. 11
13x + 15 = 19x - 9 ( being opposite sides of parallelogram)
19x - 13x = 15 + 9
6x = 24
x = 4
Also,
4y + 7 ° + 10y - 37° = 180° { being co-interior angles }
14y - 30° = 180°
14y = 210°
y = 210° / 14
y = 15°
For no. 12
5x + 38° = 8x - 19° { being opposite angles of parallelogram }
8x - 5x = 38° + 19°
3x = 57°
x = 19°
Hope it will help :)
Answer:
Step-by-step explanation:
The total number of marbles is 24 + 36 + 60 = 120
Red: 24/120 = 1/5
Blue: 36/120 = 6/20 = 3/10
Yellow: 60 / 120 = 1/2

Answer:
A. f(-3) < g(-3)
Step-by-step explanation:
Evaluating f(-3), you get ...
f(-3) = -(-3)^2 +4 = -9 +4 = -5
Looking up g(-3) in the table, you get ...
g(-3) = 1
Comparing these values, you find
f(-3) vs. g(-3) . . . is . . . -5 vs. 1
The true comparison is ...
-5 < 1
So, f(-3) < g(-3).
D. (7,0)
The original coordinates were (0,7)y and (1,5)x then I rotated it 90 degrees and the coordinates were (7,0)y and (5,1)x
