Deforestation in Africa has had the effect ofA) preventing the spread of disease

B) leading most in the country to prosperity

C) causing a lasting boom in the timber industry.

D) causing massive starvation and a migration of people

Answers

Answer: Option 'D' is correct.

Step-by-step explanation:

Deforestation in Africa has had the effect of causing massive starvation and a migration of people as the number of population of nomads is more in Africa and they live in forests and get their food from there. As forest is the main source for them for their survival.

Deforestation means "Cutting down of trees in a large number ":

So, they get affected by this .

Hence, Option 'D' is correct.

I would say D since this could cause people to have to move somewhere else due to destruction

Which equation shows y+15=3x in standard form?A. 15x−5y=1

B. 5x−15y=1

C. 15x+5y=−1

D. 15x−5y=−1

Answers

Answer:

Option A is correct.

$15x-5y=1$

Step-by-step explanation:

The standard of any equation is in the form of:

$Ax+By = C$

Given the equation: $y+(1)/(5) = 3x$

Multiply both sides by 5 we get;

$5y+1 = 15x$

Subtract 5y from both sides we get;

$1 = 15x-5y$

$15x-5y=1$

Therefore, the equation $y+(1)/(5) = 3x$ in standard form is $15x-5y=1$

Answer: 15x−5y=1

Helpp!! :Edith babysits for x hours a week after school at a job that pays $4 an hour. She has accepted a job that pays $7 an hour as a library assistantworking y hours a week. She will work both jobs. She is able to work no more than 16 hours a week, due to school commitments. Edith wants to earn at least $80 a week, working a combination of both jobs.
write an inequality to represent this,and please solve for y
WORTH 22 POINTSSSSSS

Answers

so pay=hours times pay per hour

so the babysitting job pays 4 dollers pay per hour
she works x hours
therefor the babysitting pay is 4 times x or 4x

the library job pays 7 dollars an hour
she works y hurs
therefor the library pay is 7 times y or 7y

so total pay is babysitting pay plus library pay or
4x+7y=total pay
x+y=total hours

she wants to work no more than 16 hour s aweek, means that she can work max 16 hours or
total hours<16
subsitute
x+y<16

and she wants to earn at least 80 dolars
so more than or equal to 80 dolllars
total pay >80
subsitue
4x+7y>80

so the inequalities we have are
x+y<16 and
4x+7y>80

solve for y since we want to do that
multiply the first equatl by -4
remember tha tmultipy by negative means flip sign from < to > so
-4x-4y>-64
now add to the second equation

-4x-4y>-64
4x+7y>80 +
0x+3y>16
3y>16
divide by 3
y>16/3
16/3=5 and 1/3

so she has to work more than 5 and 1/3 hours per week

basically, she will earn at least 80 dollars a week if she works at least 5 and 1/3 hours at the library and works for 16 hours total (library+babysitting)

what you should do is find the graph of the lines
x+y<16 and 4x+7y>80 and find where they intersect

the inequaltiy is 4x+7y>80 and x+y<16

4x plus 7y, this shows how much she works....

According to the Fundamental Theorem of Algebra, the graph of f(x) = x2 - 4x + 3, has roots. From the graph we can see that it has zeros.
