Answer:
x = -2
y = - 5
Step-by-step explanation:
-5y - 10x = 45
-3y + 10x = -5
------------------------Add
-8y = 40
y = -5
-3(-5) + 10x = -5
15 + 10x = -5
10x = -20
x = -2
Answer
x = -2 and y = - 5
The solution to any system graphically can be found where the 2 graphs intersect. These two graphs intersect at the point (0, 2).
12 / 3 so the answer would be 4
Answer:
2019.
Step-by-step explanation:
We have been given that for the years from 2002 and projected to 2024, the national health care expenditures H, in billions of dollars, can be modeled by
where t is the number of years past 2000.
To find the year in which national health care expenditures expected to reach $4.0 trillion (that is, $4,000 billion), we will substitute
in our given formula and solve for t as:




Take natural log of both sides:





So in the 18.5 years after 2000 the expenditure will reach 4 trillion.

Therefore, in year 2019 national health care expenditures are expected to reach $4.0 trillion.
Answer:
I do not know, but I do know the formula.
The formula is: 12pl+B where p represents the perimeter of the base, l the slant height and B the area of the base.
