Answer:
.25x+1.75=15 and x=53
Step-by-step explanation:
first subtract 1.75 from both sides
then divide by .25 on both sides
and you will get x=53
Answer: Alex is correct .
Step-by-step explanation:
Answer:
yes, (0,0) is a solution for the system of equations.
Step-by-step explanation:
y < -x + 3 ,we would then plug in the ordered pair which changes that equation to 0 < 0 +3 (which is just 0 < 3) and that is true.
Then we plug in the ordered pair for the second equation, which changes it to 0 < 2 or 0 < 0 + 2.
Now, since the inequalities are true, the ordered pair works for the system.

Answer:
A) In 2004 the population will reach 306 million.
B) In 2033 the population will reach 386 million.
Step-by-step explanation:
Given : The population of a certain country in 1996 was 286 million people. In addition, the population of the country was growing at a rate of 0.8% per year. Assuming that this growth rate continues, the model
represents the population P (in millions of people) in year t.
To find : According to this model, when will the population of the country reach A. 306 million? B. 386 million?
Solution :
The model represent the population is
Where, P represents the population in million.
t represents the time.
A) When population P=306 million.
Taking log both side,

Therefore, In 2004 the population will reach 306 million.
B) When population P=386 million.
Taking log both side,

Therefore, In 2033 the population will reach 386 million.
