Answer:
-2 (filled in circle) to 7 (open circle)
Step-by-step explanation:
for the first equation x must be the equal to or smaller than 6. so -3(-2) equals 6 but anything less than -2, let's say -3(-3), will be BIGGER than six, so -2 including -2 which is a filled in circle.
solving it:
-3(x) 6
for the second equation x must be smaller than 17. so first you take out + 3 by subtracting it, leaving the equation as 2x<14. 2(7)<14 is NOT true so anything bigger than 7 leaves it as true because 6.98934747483 can still make it true, so anything smaller than 7 which is 7 with a not filled in, or open, circle
solving it:
2x < 14
x < 7
my explanation is all over the place, but hope this helps!!!
Writing it in the form of a+bi we get 0+4i
Step-by-step explanation:
We need to evaluate expression -16 squared and write the result in form a+bi
The given expression is:
We know that
We know that 16= 4x4 = 4^2
Putting values:
So, Writing it in the form of a+bi a=0 and b=4 so, 0+4i
