To tell whether r = 2 is a solution of the inequality, substitute 2 for r and see whether the inequality produces a true or a false statement.
(2) + 4 > 8, add 2 and 4.
6 > 8, this is a false statement, because 6 is not greater than 8, so the value r = 2 is not a solution of the inequality r + 4 > 8.
Option B:
f(3) = 5
Solution:
Given function:
- If x value is less than –2, that is –3, –4, –5, –6, ... then f(x) = –x².
- If x value is greater than or equal to –2 and less than 0, that is –2 and –1 then f(x) = 3.
- If x value is greater than or equal to 0, that is 0, 1, 2, 3,... then f(x) = x +2.
<u>To find the value of f(3):</u>
Here x value is 3 which is greater than 0 (3 > 0).
Therefore, f(x) = x + 2.
Substitute x = 3 in the above function.
f(3) = 3 + 2
f(3) = 5
Hence option B is the correct answer.
I got x equals 3 and for the who equation I got 30, you can see the work in the picture
627/100 or 6 27/100 is the answer
Answer:
Abel to Ben: 6
Abel to Carl: 3
Ben to Carl: 0.5
Step-by-step explanation:
First we formulate the problem in equations:
Abel = 6 * Ben
Cale = Abel / 3
If Cale's score is Abel's score over 3, so Abel's score is 3 times Cale's score.
If Abel's score is 6 times Ben's score, and 3 times Cale's score, then Cale's score is 2 times Ben's score (so Ben's score is 0.5 times Cale's score)
So, the ratio between all scores are the following:
Abel to Ben: 6
Abel to Carl: 3
Ben to Carl: 0.5
