For this case we have the following inequality:

$9(2x+1) < 9x - 18 < br />$

Solving the inequality we have:

Distributive property:

$18x+9$

Combine similar terms:

$18x-9x$

$9x$

From here, we clear the value of x:

$x$

Therefore, the solution is given by:

(-∞, -3)

The point that belongs to the solution is:

$x=-4$

so the value of x is in the solution set is:

A: -4

Sure hope this helps

Scilla [17]

Answer:

{12,2}

Step-by-step explanation:

From the given graph it is clear that the initial point of the vector is (-5,0) and the terminal point (7,2).

If initial point of a vector is $(x_1,y_1)$ and terminal point is $(x_2,y_2)$ , then

$\overrightarrow{v}=(x_2-x_1)i+(y_2-y_1)j$

Using this formula, we get

$\overrightarrow{v}=(7-(-5))i+(2-0)j$

$\overrightarrow{v}=12i+2j$

$\overrightarrow{v}=$

Using braces, we get

$\overrightarrow{v}=\{12,2\}$

Therefore, the required vector is {12,2}.

Answer:

1. This is a "RANDOMIZED CONTROLLED EXPERIMENT".

A randomized controlled experiment is a type of research study, were the researcher randomly select samples in other not to be biased. This samples are separated into two groups, which are the experimental and the controlled group.

2. The research has a treatment group and a controlled group.

A treatment group are those group that received some special treatment from the researcher, it can also be called the experimental group. According to the research, the treatment group are those who are in the POVERTA scheme. That is the 320 communities.

A controlled group are those group that were not given any special treatment, but are , separated and studied. According to the research the controlled group are those 185 communities

3. This research provides evidence that being in a community receiving POVERTA benefits is associated with a lower rate of childhood illness. Because after two years, it was noticed the children in the community that receives POVERTA has low rate of illness, than the children in a community that doesn't receive the benefits of POVERTA.

4. This study does not provide evidence that being in a community receiving POVERTA benefits causes a lower rate of childhood illness. Because the research did not involve treatment of illnesses and they is no experimental evidence that shows that POVERTA benefits is interrelated with illness, as illness involves the internal functions of human body.

5. Such study will be called a "RANDOMIZED CONTROLLED EXPERIMENT". Because their randomly isolated themselves, and the POVERTA treatment was not given to them. The researcher was not based in selecting them not to participate.

yanalaym [24]

Answer:

Area = 867 meters

Step-by-step explanation:

You have a rectangle. This means opposite sides are equal. If you set these expressions equal to each other, you will get two equations with two unknowns, x and y. Next, solve the system of equations to find x and y. Then, use the values to find the length and width of the rectangle. Last, multiply length × width to find the area.
