Examples: Determine if the graph is a function. If it is, state the domain and range.

NemiM [27]

Answer:

Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.Jan 8, 2019

In the equation 5x-2=-x-20, What is the value of x?<br> a. 2<br> b. -1<br> c. -3<br> d. -2

mestny [16]

Answer:

C choice.

Step-by-step explanation:

$5x - 2 = - x - 20 \\$

First, we move the same terms to the same side.

$5x + x = - 20 + 2 \\ 6x = - 18$

Then we move 6 to divide - 18.

$x = \frac{ - 18}{6} \\ x = - 3$

Combine like terms. What is a simpler form of each expression?<br> 30 - 5d - C + 3d

borishaifa [10]

30 - 5d - c + 3d

In this equation there are two numbers which have the letter d with them. These would be like terms.

You have -5d + 3d which equals -2d

The simplified form would be 30 -2d -c

Do the results support or contradict the common belief that the mean body temperature is 98.6degreesF? A. The results contradic

nata0808 [166]

Answer:

A. The results contradict the belief that the mean body temperature is 98.6 °F because both the mean and the median are less than 98.6 °F.

Step-by-step explanation:

Assume the temperature data were those in the table below.

You would have calculated that

Mean = 97.9 °F

Median = 97.9 °F

These observations contradict the belief that the mean body temperature is 98.6 °F.

A 2017 study found the mean oral temperature of more than 35 000 British patients was 97.9 °F.
