Use the Commutative Property on the expression 7x - 5.

Mathematics
1 answer:
Schach [20]3 years ago

Answer:

<h2>-5 + 7x</h2>

Step-by-step explanation:

The Commutative Property states that the order of addition or multiplication does not matter.

EXAMPLE 1 : 1 + 2 = 2 + 1 = 3

EXAMPLE 2: 3 x 4 = 4 x 3 = 12

It appears that we cannot use the commutative property on this expression. But we can. First, we need to change - 5 = + -5.

7x - 5 = 7x + -5

Because we now have addition, we can prove the commutative property.

-5 + 7x = 7x + -5

I'm always happy to help :)

I don’t understand this one
Masja [62]

Answer:

  see below

Step-by-step explanation:

Put -1 where x is in each expression and evaluate it.

__

You will find that the expression is zero when the numerator is zero. And you will find the numerator is zero when it has a factor that is equivalent to ...

  (x +1)

Substituting x=-1 into this factor makes it be ...

  (-1 +1) = 0

__

Evaluating the first expression, we have ...

\dfrac{4(x+1)}{(4x+5)}=\dfrac{4(-1+1)}{4(-1)+5}=\dfrac{4\cdot 0}{1}=0

This first expression is one you want to "check."

You can see that the reason the expression is zero is that x+1 has a sum of zero. You can look for that same sum in the other expressions. (The tricky one is the one with the factor (x -(-1)). You know, of course, that -(-1) = +1.)
