Answer:
Step-by-step explanation:
if there are two numbers a and b.then
1. a+b=b+a ,commutative under addition.
2. ab=ba,commutative under multiplication.
If there are three numbers a,b,c then
1. a+(b+c)=(a+b)+c,associative under addition.
2.
a×(b×c)=(a×b)×c ,associative under multiplication.
Answer:
i think u have to use subtraction
Answer:
- An <em>independent</em> variable can be assigned any value. The variable that changes depending on the <em>independent</em> variable is called the <em>dependent</em> variable.
- If x is the independent variable, then <em>y</em> would be considered the dependent variable and will change depending on the value of <em>x</em>.
Step-by-step explanation:
The key word is "depending". The <em>dependent</em> variable changes depending on the <em>independent</em> variable.
A vertical line is a line that is straight up and down. It doesn't tilt. Think of a flagpole as one of many examples.
I suggest plotting the point (-0.4, 0.3) on the coordinate grid. Draw a vertical line through this point. You'll see that there are other points on this line such as...
(-0.4, 0) and (-0.4, 2) and (-0.4, 5)
and so on...
There are infinitely many points on this line. All of them have the same x coordinate of -0.4 since that's what the original point has. Y can be anything you want.
So the equation of this line is simply x = -0.4 to indicate "force x to be -0.4 and y can be whatever you want"
Answer:
25
Step-by-step explanation:
2-3-4-5+5*7
PEMDAS
Multiply and divide first
2-3-4-5+35
Then add and subtract from left to right
-1 -4-5+35
-5-5+35
-10+35
25
