Answer:
8) 1
9) -4
10) -3
11) -1
12) 1
13) doesn't exist
14) 1
15) doesn't exist
Step-by-step explanation:
8) when we approach x=-8 from left and from right, the function tends towards the value 1
9) when we approach x = -7, from the left the function gets towards 0, while when we approach it from the right it gets closer to -4
10) f(-3) = -3
11) When x approaches the value 4 from the left and from the right, f(x) gets closer to -1
12) f(4) is defined as 1
13) f(6) doesn't exist
14) When x approaches 6 from the left and from the right, the function approaches 1
15) When x approaches the value 7 from the left the function gets closer to 2, while when we approach x = 7 from the right the function gets toward 7. Because of this discrepancy, the limit doesn't exist.
Ok so...
y=-160-9(-13)
y=-160-117
y=43
hope i helped
Answer:
20/28 which is about 71%
Step-by-step explanation:
so first you add up how many balls there are. 8+20=28. So 28 is the denominator for the fraction. there are 20 black balls, so that is the numerator. so 20/28 is the fraction. then you divide 20 by 28 to get the rounded percent.
