Answer:

 7 - 2i

Step-by-step explanation:

Here we have two complex numbers and wish to combine them.  Complex numbers have real and imaginary parts.  We sum up the real parts and the imaginary parts separately:

 -9 - 7i

+16 + 5i

------------

 7 - 2i      This is the sum of -9 -7i and 16 + 5i.

Which graph represents the solution please explain
zubka84 [21]

Answer:

Graph D

Step-by-step explanation:

First, solve the equation

5 + 8x < 3(2x + 4)

5 + 8x < 6x + 12

Collect like terms

-6x + 8x < -5 + 12

2x < 7

Divide both sides by 2

x < 7/2

x < 3½

The graph that shows that x < 3½ is graph D.

Int var1 = 0b0001; int var2 = 0b1111; int results1 = var1 &amp; var2; int results2 = var1 | var2; int results3 = var1 ^ var2; in
Afina-wow [57]
<span>Int var1 = 0b0001;
int var2 = 0b1111;
int results1 = var1 & var2;
int results2 = var1 | var2;
int results3 = var1 ^ var2;
int printit = results1 + results2 + results3;
 
what are the values for results1, results2, results3 and printit after executing the code?
notes:
1. faster responses will be obtained if your code is presented line by line (in a file) before posting.
2. please specify language, many languages use the same syntax but could have differences in interpretation
-------------------------------------------------------------------------------

Assuming Java as the language.  C is similar.
</span><span><span>& bitwise AND &
^ </span><span>bitwise exclusive OR
</span><span>| bitwise inclusive OR

So 
results1=var1&var2=0b0001&0b1111=0b0001
results2=var1|var2=0b0001&0b1111=0b1111
results3=var1^var2=0b0001&0b1111=0b1110
printit=results1+results2+results3=0b0001+0b1111+0b1110
=0b10000+0b1110
=0b11110   

Note: by default, int has 4 signed bytes, ranging from decimal -2147483648 to +2147483647
