Answer:

B. Subtract 12 from both sides

Step-by-step explanation:

You must be confused on why I say this. But hold tight, I have an explanation.

Because 12 is on the front side of the minus sign, it is actually positive. That means you must subtract it from both sides.

But what about 4x? Well, it is actually negative! Because the 12 is reduced to zero, the equation is technically 0 - 4x = 42. However, we just remove the 0 to make -4x = 42.

By the way, the fully solved equation is: x = -10.5 or x = -10 1/2

Hope this helps!

Consider this function.
charle [14.2K]

Answer:

3. Since the range of the original function is limited to y> 6, the domain of the inverse function is x ≥ 6.

Step-by-step explanation:

The domain of a function is the range of its inverse, and vice versa. The only answer choice that expresses this relationship is choice 3.

__

Comment on the answer choice:

The slope of the function is undefined at x=4, so restricting the function domain to the portion with positive slope means the domain restriction of the function is x > 4. That also means the range restriction of the function is y > 6. The domain restriction of the inverse function is the same: x > 6, not x ≥ 6. The answer choice has an error.

astronomers measure large distances in light years one light year is the distance that light can travel in one year or approxima
sveticcg [70]
What you can do in this case is the following rule of three to find the result:
 1 light year ---> 5.88 * 10 ^ 12 miles
 3.2 * 10 ^ 2 light year ---> x
 Clearing x we have:
 x = ((3.2 * 10 ^ 2) / (1)) * (5.88 * 10 ^ 12)
 x = 1.88 * 10 ^ 15 miles
 answer:
 In scientific notation, approximately it is 1.88 * 10 ^ 15 miles
