Which number produces an irrational number when multiplied by 1/2
1 answer:
Quick answer
Any irrational number. I can't think of any exception to this statement.
sqrt(5) is irrational. 1/2 * sqrt(5) is still irrational.
-sqrt(5) is irrational. -1/2 * sqrt(5) is still irrational
2 + sqrt(5) is irrational. Multiplying this by 1/2 is still irrational.
1/2(2 + sqrt(5) = 1 + 1/2 * sqrt(5) ) is irrational.
Conclusion
There are no exceptions to this. All irrational numbers produce irrationals when multiplied by 1/2

Answer: -7/3≤t≤5/3
Step-by-step explanation:
|2t + 2/3|≤4
2t + 2/3≤4
(2t + 2/3≤4)*3
6t+2≤12
6t≤10
t≤10/6
<u>t≤5/3</u>
2t + 2/3>=-4
(2t + 2/3>=-4)*3
6t + 2>=-12
6t>=-14
t>=-14/6
<u>t>=-7/3</u>
-7/3≤t≤5/3
Answer:
<em>x = 5</em>
Step-by-step explanation:
5(x + 4) - 8 = x + 32
5x + 20 - 8 = x + 32
5x + 12 = x + 32
5x - x + 12 = 32
5x - x = 32 - 12
4x = 32 - 12
4x = 20
x = 5
