Answer:

4x+3−9x= 3-5x

5+3.2n−6−4.8n= -1.6n-1

2y−5(y−3)= -3y-15

−1/2(8b+3)+3b= -1b-1.5

Step-by-step explanation:

Add the numbers with the variables.

4x-9x= -5x

Then add the rest of the equation to it.

3-5x

Again, add the numbers with the variables and simplify the others.

3.2n- 4.8n= -1.6n

5-6= -1

That leads to....

-1.6n-1

Distribute the 5 into the parenthesis.

2y-5y- 15

Now, subtract the variables.

-3y-15

Distribute into the parenthesis.

-4b+(-1.5)+ 3b

Add the variables together.

-1b-1.5

Does the table of values below represent a proportional relationship?
ladessa [460]

Answer:

No

Step-by-step explanation:

The constant of proportionality is k = y/x. In this case, k is 5. When you multiply k which is 5 with the x value you should get the y value. You will see that 2 X 5  = 10, 3 X 5 = 15, and 5 X 5  = 25 but 4X 5 is not equal to 24. This means the ordered pair (4, 24) does not lie on the straight line that is formed where all the other ordered pairs (2,10), (3,15), and (5,25) lie.

For a proportional relationship in a table, the k is constant for all the ordered pair x and y values. All the ordered pairs in the table should also lie on the same straight line.

So the answer is no.

What ethical issues have been raised by the scientific community's commitment to ensuring that experimental treatments are not
e-lub [12.9K]

Answer:

They include;

1. Fewer chances of determining how effective the treatment plan would be.

2. Inability of every patient to access the experimental treatment.

3. Difficulties in making knowledgeable decisions on the treatment plan.

4. Determining that the experimental treatments are offered with the right motive.

Step-by-step explanation:

In medical treatment administration, it is standard practice that drugs undergo clinical trials on test animals before they are administered to patients. However, some sicknesses are without known drugs for treatment or may have drugs that are still undergoing experiments and trials. In such cases, patients may want to be treated with experimental drugs.

Ethical issues such as the above-listed can arise from this. The foremost of them all is the fact that the treatment might prove ineffective thus causing more problems to the patient.

Inequalities are regions, the attached picture shows us a region located between -3 and 3, the dots used are solid, this means that the value '3' is include in the region.

Hence the variable is narrowed to -3 and 3.
