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 :)
0.43 should be the answer.
Let's write 2 equations from the two statements given.
<em>Sarah spent 10 dollars on both oranges and apples</em>
<em />
Let the price of oranges be "x" and price of apples be "y", thus we can write:

Oranges cost 3 less than apples, thus we can say:

We can substitute this into the first equation and solve for y:

Thus, let's solve for x now,

We want the price of oranges (x), thus,
<em>Price of Oranges = $3.50</em>
Answer:

Step-by-step explanation:
The given expression is

The tangent of -1 is defined, it's around -0.02.
The tangent is a trigonometric function with a period of
, where each period is separated by a vertical asymptote which indicates that the function is not determined through all its domain, that's what the question refers to when it says "if is undefined, enter undefined".
However, at
, the tangent is determined, that means, there's no asymptote on that coordinate, that's why it has a "determined value", which is -0.02 approximately.
