Both angles are complementary angles, or they together equal 180°, so you will add both expressions and set equal to 180. This will get you (3x+2)+(5x+10)= 180. We then solve for x.
8x +12 = 180. We subtract 12 on both sides.
8x = 168. We divide by 8 on both sides.
x=21
We can then plug x into each expression to get the angle for each.
Angle 1: 3(21)+2=65°
Angle 2: 5(21)+10=115°

Describe the function over each part of its domain. State whether it is constant, increasing, or decreasing, and state the slope

Amanda [17]

The attached image completes the question.

Answer:

- The part (0, 12000) is constant and the slope is zero

- The part (12000, 38000) is decreasing and slope is negative 0.26.

Step-by-step explanation:

Checking the given graph, we see that

For x = 0 to x = 12,000, the values of y are unchanged. For this, we say it is constant.

The slope here is: 0.85 - 0.85 = 0

For x = 12,000 to x = 38,000, the values of y are decreasing. For this, we say it is negative.

The slope here is: 0.59 - 0.85 = -0.26.

Kira looked through online census information to determine the average number of people living in the homes in her city. What is

Goshia [24]

First we need to identify if the data is qualitative or quantitative.

The data is average number of people living in the homes.

Qualitative data as its name indicates is an attribute or characteristic. It can not be measured e.g color. Quantitative data is such a data which can be counted or measured.

Since the average number of people can be counted and measured, the data is Quantitative.

In an observational study the individuals are observed. In the given case, Kira did not observed the individuals to gather the data, rather she used an Online resource to gather the data.

Therefore, the correct answer will be:
Kira used published data that is quantitative.
