X + y = 12 . . . . . . . . (1)
x - 3y = -30 . . . . . . . (2)
(1) - (2): 4y = 42
y = 10.5
Answer:
17=J
L= 180-17
= 163
K=163
L=163
J=17
Step-by-step explanation:
83.3
Just add up all the numbers and divide by 6, as there are six numbers in this set of numbers
35 divided by 2 1/2
change 2 1/2 to an improper fraction
2 1/2 = 5/2
35 divided by 5/2
copy dot flip
35 * 2/5
70/5
14
you can make 14 plots
Average rate of change is (f(8) - f(-6))/(8 - (-6)) = ((<span>|8 + 3| -1) - (</span><span>|-6 + 3| -1))/(8 + 6) = ((</span><span>|11| -1) - (</span><span>|-3| -1))/14 = ((11 - 1) - (3 - 1))/14 = (10 - 2)/14 = 8/14 = 4/7</span>
