The real part of given complex number -3 + 9i is -3
<em><u>Solution:</u></em>
We have to find the real part of complex number -3 + 9i
A Complex Number is a combination of real Number and an imaginary Number
<em><u>The general form of complex number is:</u></em>
a + bi
Where "a" and "b" are real numbers and i is the unit imaginary number
The given complex number is:
-3 + 9i
On comparing the above complex number with general form of complex number we get,
Real part = -3
Thus real part of given complex number is -3
First we need to arrange the numbers in this number set from smallest to biggest:17,18,24,27,31,39,42,47,55,65. Then there are 10 numbers in this number set. So when we calculate the median, we need to find the middle two numbers and calculate their average. So the median is (31+39)/2=35. SO the answer is B
Solutions
x+ 3 <= 10
Subtract 3 from each side:
x <= 7
B.) 8(x+4) is the best choice
