23 below zero means you will actually subtract (remove) 23 from zero.
This can be represented using the following expression:
0 - 23
To represent this as an integer, this means you will use a negative sign to represent the removal or subtraction of the number followed by the number removed which is 23, therefore:
The integer to represent this is -23.
Answer:
-5/2+-1/2√37≤x≤-5/2+1/2√37
Step-by-step explanation:
Step 1: Find the critical points
-x^2-5x+3=0
For this equation: a=-1, b=-5, c=3
−1x^2+−5x+3=0
x=−b±√b2−4ac/2a
x=−(−5)±√(−5)2−4(−1)(3)/2(-1)
x=5±√37
/−2
x=-5/2+1/2√37
Step 2: Check intervals in between critical points
x≤-5/2+1/2 √37 (Doesn't work in original inequality)
-5/2+-1/2√37≤x≤-5/2+1/2√37 (Works in original inequality)
x≥-5/2+1/2 √37 (Doesn't work in original inequality)

Answer:
Step-by-step explanation:
2X+4)+(2X+4)+X+X=38
Lets add our X's and then add our whole numbers. 6X+8=38
Lets work our sentence by subtracting 8 from each side of the equal sign.
6X+8–8=38–8
6X=30
Lets divide each side by 6.
6X/6=30/6
X=5 now lets prove 5 is X.
(2×5+4)+(2×5+4)+5+5=38
(14)+(14)+5+5=38
28+10=38
38=38
X is equal to 5.
