To simplify divide by 4
Have in mind that as you cannot take the square root of a negative number, this means that x-4 CANNOT be negative. So it's either 0 or it's positive.
So we proceed like this:<span>x−4≥0</span>
<span>x−4+4≥0+4</span>
<span>x≥4
</span>So the domain is <span>{<span>x|x≥4</span>}
</span>In interval notation, the domain is <span><span>[4,∞)
I hope thi can help you</span></span>
Step-by-step explanation:
3x+27=-2+18
3x+27=16
3x=16-27
3x=-11
x=-11/3
but i think the question is wrong i mean does it have x after -2??
