You had mistakes, so I did all of them.
9) -6(1 + 11b) = -6 - 66b
10) -10(a - 5) = -10a + 50
11) -3(1 + 2v) = -3 - 6v
12)-4(3x + 2) = -12x - 8
13) (3 - 7k)*-2 = -2 * (3 - 7k) = -6 + 14k
14) -20(8x + 20) = -160x - 400
15) (7 + 19b)*-15 = -15(7 + 19b) = -105 - 285b
16) (x + 1) * 14 = 14(x + 1) = 14x + 14
Answer:
1
Step-by-step explanation:
We can use the slope formula
m = (y2-y1)/(x2-x1)
= (5-8)/(-8 - -5)
= -3/(-8+5)
= -3/-3
= 1
Option C is correct.
34.875
20, 31, 33, 35, 55, 57, 58, 59, 72, 73, 79, 86, 87, 88
The data set is split by digit. So 2|0 becomes 20. 5|5 becomes 55. Using this method, the data set is
