Answer:
x = 2
Step-by-step explanation:
3x - 5 = 1
Adding 5 to both sides gives us:
3x - 5 + 5 = 1 + 5
3x = 6
Dividing the equation by 3 gives us:
3x / 3 = 6 / 3
x = 2
The answer will be B. Hope it help!
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.
Step-by-step explanation:
By solving, I am assuming that you want to find the zeros.
So to find what x equals, first, you factor out an x.
3x² - 4x = 0
x(3x - 4) = 0
Here, you can separate the equation into two different equations to solve for x.
- <em>3x - 4 = 0</em> and <em>x = 0</em>
- x =
and x = 0
Those are your zeros.
And for its graph, you can always look to an online graphing calculator. I used Desmos.
