Answer:
Since zero has no value, it does not need to be included when writing a number in expanded form.
Step-by-step explanation:
There are an infinite number of different equations that have
x=2/3 as the solution, or as one of several solutions.
You didn't show us your list of choices, so we can't help you
pick the right one.
Just take each choice, one at a time. Write ' 2/3 ' in place of 'x'
in each equation, and simplify everything. You'll wind up with
one equation that's true, and the others will say something that's
nonsense.
The one that's true is the one that has x=2/3 as its solution.
Answer: The death is 500, there will be 125 carbon-14 atoms, and after 25,000 years.
Step-by-step explanation:
I just took a test and got it right, I can't do math (;
The system has:
- No solutions for two parallel lines.
- 1 solution for two nonparallel lines.
- Infinite solutions for two equations that describe the same line.
<h3>How to identify the number of solutions for the systems?</h3>
A system of two linear equations is given by:
y = a*x + b
y = c*x + d
1) The system has no solutions when both lines are parallel lines, this happens when both lines have the same slope and different y-intercept.
y = a*x + b
y = a*x + d
2) The system has one solution when the lines have different slopes:
y = a*x + b
y = c*x + d
3) The system has infinite solutions when both equations describe the same line:
y = a*x + b
y = a*x + b
