The answer is -4
-4 + -6 = -10. And -4- -6 = 2
Answer:
sameeeee i suck at math too
Which set of ordered pairs represents a function? {(0, 1), (1, 3), (1, 5), (2, 8)} {(0, 0), (1, 2), (2, 6), (2, 8)} {(0, 0), (0,
11111nata11111 [884]
Answer: {(0, 2), (1, 4), (2, 6), (3, 6)}
Step-by-step explanation:
For a relation to be considered a function, each x-value needs to have one corresponding y-value--it cannot have more than 1.
Since all the other sets of ordered pairs feature points with two x-values with different y-values, the set above is the only function of the provided options.
ANSWER
0.0952
EXPLANATION
We have that Stephen surveyed 21 of his classmates and obtained the data in the table given.
To find the probability for which a randomly selected classmate has 3 credit cards in their wallet, we have to divide the number of people that had 3 credit cards in their wallet by the total number of people surveyed.
From the frequency table, we have that only 2 classmates had 3 credit cards in their wallets.
Therefore:
That is the answer.
Answer:
All are valid
Step-by-step explanation:
Px - 43 = -42x + Q (rearrange)
x = (Q+43) / (P + 42) <----Substitute options for P & Q into this equation to see which combination gives exactly 1 solution for x
A) P=42, Q = 42; x = (42+43) / (42+42) = 1.011 (only 1 solution = valid)
B) P=43, Q = -42; x = (-42+43) / (43+42) = 0.012 (only 1 solution = valid)
C) P=-43, Q = -43; x = (-43+43) / (-43+42) = 0 (only 1 solution = valid)
D) P=42, Q = 43; x = (42+43) / (42+42) = 1.023 (only 1 solution = valid)
