No it isnt a function. because the number are not at equal distances. X isn't equal and neither is Y, they have to correspond to make a function.
Answer: 17
Step-by-step explanation:
In this problem, the phrase "a number" can be interpreted as a variable. In this case, let the variable be "x."
Thus, "twice a number" = "2x"
"and 13" = "+ 13"
"is 47" = "= 47"
Thus, the problem is simply 2x + 13 = 47.
Then, simply subtract 13 from both sides to get 2x = 34.
Then, simply divide both sides by 2 to get x = 17.
Because "the number" is "x," the number is 17.
Hope it helps :) <3 and lmk if you need more help
Answer: y should be in the interval (0.4, 4)
Explanation:
The binomial 5y - 7 is in the interval (-5, 13) if and only if
-5 < 5y - 7 < 13
Solving the inequalities in this form is the same as solving equation. So, we add all sides of the inequalities by 7 so that
2 < 5y < 20
Then, we divide both sides by 5 to get the following inequalities
0.4 < y < 4
Hence y should be in the open interval (0.4, 4).
Answer:
D. This quadratic equation two complex solutions.
Step-by-step explanation:
Equating it with
a = 5, b = 6, c = 2
is negative.
Therefore, this quadratic equation two complex solutions.
Based on my information, I believe that this would actually be a statistical because the question contains extra information that would help you narrow down the answer. The question could have been a lot easier, such as: "how much do horses weigh", but it does not, it
contained extra data that would help answer the question to the point.
