Answer:

All real numbers

Step-by-step explanation:

We can start out by knowing that the domain of a graph is, the side, to side from the x axis directions.

We can see that the line continues of the graph shown, meaning it is infinite. Meaning the answer is the domain is all real numbers.

We can double check by seeing that the other options don't work or aren't enough:

$x\geq 2\\and\\x\leq 2\\and\\x\geq -4$

The first wouldn't work becuase, yes that is part of the answer, but not the whole answer. The same goes for the others as well, they are on the line and are correct, but the best, and full answer is "All real numbers"

A thermometer measures temperature to the nearest 0.5°C which measurement shows an appropriate level of precision for the thermo

statuscvo [17]

Answer:

Step-by-step explanation:

To the nearest 0.5°C means basically 1 digit after the decimal point.

0.5 has 1 digit (5), after the decimal point. To the nearest 0.5 means that the answer should have 1 digit after the decimal point.

For example, if we were to round 14, to the nearest 0.5, we would need to write it as 14.0 (with 1 digit after decimal).

Now, looking at the answer choices, we eliminate A because it has 2 digits after decimal. We eliminate B and C because there is NO DIGIT after decimal. And we accept D, because it has 1 digit after decimal. Hence, this is correct to the nearest 0.5°C.

Answer is D

Which of the lines graphed in the diagram represents the equation 6x + 4y = 8

Blizzard [7]

In order to easily discern which graph is a proper representation of 6x + 4y = 8, you first need to convert the equation to y = mx+ b, also known as slope-intercept form. Here's how you can do this:
6x + 4y = 8
4y = -6x + 8
y = -1.5x + 2
The +2 tells you that your line will intercept the vertical y-axis at (0, 2). This narrows it down to graphs a and d. Then, because you have a NEGATIVE number in front of your x (it's -1.5), you can tell that your graph will be going down as it moves from left to right. This leaves you with graph d as your answer!

The population of a once very popular city of 250,000 people has been decreasing by 3.5% each year. Write an exponential decay f

vladimir2022 [97]

Y= 250000-8750t

3.5 percent of 250000 is 8750, if that’s the amount decreasing each (t) years, you multiply that number by number of years taken into account.
