We need to have (x^2 - 3x + 2) ≥ 0
<span>That is the same as (x - 2) * (x - 1) ≥ 0 </span>
<span>This happens when both (x - 2) and (x - 1) ≥ 0, which is when x ≥ 2 and when x ≥ 1, so it happens when x ≥ 2. </span>
<span>It also happens when they are both ≤ 0, which is when (x - 2) and (x - 1) are both ≤ 0. That happens when x ≤ 2 and when x ≤ 1, in other words, when x ≤ 1 </span>
<span>Therefore the domain is {x is real and either x ≤ 1 or x ≥ 2 <---- Answer </span>
<span>For x in (1,2) (x-2 is negative) and (x - 1) is positive, so their product is negative. </span>
Answer:
x = 6.4 feet.
Step-by-step explanation:
If a triangle has side lengths a, b, and c then its perimeter (P) will be given by ( a + b + c ).
Now, in this problem, the perimeter of a triangle is given to be 27.1 feet,
And its sides are 9.8 feet, 10.9 feet, and x feet.
Therefore, 27.1 = ( 9.8 + 10.9 + x )
⇒ 27.1 = 20.7 + x
⇒ x = 6.4 feet (Answer)
The atom's place on the table is determined solely by its number of protons
- A periodic table is a table containing different elements and arranged across the periods and groups of the table.
- The elements in a periodic table are numbered and arranged based on their atomic number.
Since the atomic number is equal to the number of protons an element contains, hence we can conclude that <u>the atom's place on the table is determined solely by its </u><u>number of protons</u>

Step-by-step explanation:
Answer:
(3, -18)
Step-by-step explanation:
To get from (-1, -8) to (-3, -12), one moves 2 units to the left and 4 units down.
Thus, the coordinates of (5, -7) under the same translation are:
(5 - 2, -7 - 11), or (3, -18)
