Hello,
Let's r the ration
We suppose x ≠0
x=r*(x-2)==>r=x/(x-2)
x+3=r*x==> (x+3)/x=x/(x-2)==>(x+3)(x-2)=x²
==>x²+3x-2x-6=x² ==>x-6=0==>x=6
x-2=6-4=4
x=6
x+3=6+3=9
6=4*3/2
9=6*3/2
Ration 3/2
First term: 4
Undercoverage might lead to bias in this study due to the risk of collecting data from a small number of people who feel strongly about the research study in this scenario.
<h3>What is Undercoverage bias?</h3>
This refers to a type of sampling bias which occurs when the research population aren't adequately represented in the study.
This type of sampling involves getting data from a selected few people who may have the same opinion or view about the study which doesn't depict the true representation of the population.
This makes the study to be biased which is why undercoverage is usually avoided when conducting a research.

Answer:
a. 1
b. 5
Step-by-step explanation:
<h3>a.</h3>
Ordered pairs are (x, f(x)). You want f(2), so you look for an ordered pair that lists 2 as the first number. That one is (2, 1). This means f(2) = 1.
__
<h3>b.</h3>
f(2) is plotted as the point (2, f(2)). That is, the x-coordinate of the point will be 2. The point that has x-coordinate 2 is (2, 5).
As above, this means f(2) = 5.
