\huge \boxed{\mathbb{QUESTION} \downarrow}

  • By substitution, justify that x = − 6 is a solution to x − 2 = − x − 14.

\large \boxed{\mathbb{ANSWER\: WITH\: EXPLANATION} \downarrow}

First, let's substitute the value of x as -6 in the equation.

\tt \: x - 2 =  - x - 14 \\  \dashrightarrow \: \tt \:  ( - 6) - 2 =  - ( - 6) - 14

Now, let's solve it.

\tt \: ( - 6 ) - 2 = - ( - 6 ) - 14

Subtract 2 from -6 to get -8.

\tt \: -8=-\left(-6\right)-14

The opposite of -6 is 6.

\tt \: -8=6-14

Subtract 14 from 6 to get -8.

\tt \: -8=-8

Compare -8 and -8. We can see that both the LHS & RHS are equal to each other. So, hence we proved that <u>x = − 6 is a solution of x − 2 = − x − 14.</u>

Assuming that other factors are equal, how are the birthrate and death rate
igor_vitrenko [27]

Answer:

In a stable population, if all the other factors are equal then the birth rate should be equal to the death rate in order to maintain the stability.

Explanation:

The birth rate is described as the number of births taking place in an area per year. Death rate is described as the number of deaths taking place in an area in a year.

In order to maintain a stable population, the birth rate should be equal to the death rate. If there are more number of births than the number of deaths, then it would mean more competition for resources like food, water etc.

How does inbreeding alter genotype and allele frequencies? see section 23.2 ( page 462)?
mamaluj [8]

Answer;

Homozygotes increase in frequency in the population over generations. and genetic variation decreases in the section of the population.

Explanation;

-Inbreeding is the mating of relatives or, mating of individuals with at least one common ancestor. With continuous inbreeding, genetic variation is lost and homozygosity is increased, enabling the expression of recessive deleterious alleles in homozygotes.

-By inbreeding, individuals are further decreasing genetic variation by increasing homozygosity in the genomes of their offspring.
