Step-by-step explanation:

So the first set of paranthese don't really matter so you can rewrite it to this

-7+6-(-2x+9x-2)

Then  infront of the ( there is a - which means a -1. Now just do the disbutive property.

-7x+6+2x-9x+2

ycow [4]

Answer:

Choices 2, 3, and 5  are correct.

Step-by-step explanation:

Complete question is:

Check all that apply.

1. ln ab² - ln a

2. ln a + 2 ln b  

3. ln a² + ln b² - ln a

4. 2 ln ab

5. ln ab²

ANSWER:

The given expression is : 2 ln a + 2 ln b - ln a

It simplifies to: ln a + ln b² = ln ab²

Checking the given options.

1. ln ab² - ln a   = ln (ab²)/a = ln b²

  FALSE

2. ln a + 2 ln b = ln ab²

  TRUE

3. ln a² + ln b² - ln a = ln (a²b²)/a = ln ab²

  TRUE

4. 2 ln ab = ln a²b²

  FALSE

5. ln ab²

Determine if the following relations represent y as a function of x.
lana [24]
<h3>Answers:</h3>
  • A) No, it is not a function
  • B) Yes it's a function
  • C) Not a function
  • D) Yes it's a function
  • E) Yes it's a function

================================================

Explanation:

If y has an exponent of 2, 4, 6, etc (basically any even number) then it leads to having inputs with multiple outputs.

Consider something like y^2 = x. If x = 100, then y = 10 or y = -10 are possible. A function can only have exactly one y output for any valid x input. Similar issues happen for things like y^4 = x and so on. So this is why A and C are not functions.

The other equations do not have y values with such exponents, so we can solve for y and have each x input lead to exactly one y output. Therefore, they are functions.
