The domain of y=4/x^2+1 is (−∞ , ∞)
Answer:
-21 < 3x < -6
OR -6 > 3x > -21
Step-by-step explanation:
Take a part each section of the word form. Translate each section into algebraic form (numbers and symbols) and put the sections back together.
"Three times x": 3x A number and variable together multiply
"is less than -6": < -6
"and greater than -21": > -21
When writing that a number is > or <, you can also write the number on the other side, change the symbol, and it will mean the same thing.
< -6 is the same as -6 >
> -21 is the same as -21 <
<u>The number remains on the same open or closed side of the symbol.</u>
The problem tells use that "3x" is between -21 and -6. Put the sections back together, but write 3x in the middle.
-21 < 3x < -6
You can also write:
-6 > 3x > -21
You can write them either way, but some teachers prefer smaller number to bigger number from left to right.
I believe it's 23 as your answer
Option c. The range of window for the data is given as 0 Less-than-or-equal-to x Less-than-or-equal-to 20, 0 Less-than-or-equal-to y Less-than-or-equal-to 20
<h3>How to solve for the range of the data</h3>
We have the equation to be
y = −3x + 17,
and y = 5x - 23
We have to make the two equations to be equal
This would then give us
−3x + 17 = 5x - 23
The next step is to take the like terms
3x - 5x = -23-17
-2x = -40
From you we have to divide by -2
x = 20
The range would be written as
0 ≤ x ≤ 20, 0 ≤ y ≤ 20
