1/3 z - 12 = 36
1/3 z - 12 + 12 = 36 + 12
1/3 z = 48
1/3 z = z/3
Then multiply by the denominator, 3 to get 3 on other side of the equation.
3• z/3 = 48 • 3
z = 48 • 3
z = 144.
The solution to your problem is z = 144
Answer:
The populaton in year 1991 will be of 5178.9 million of people
and the population in year 2020 will be of 8524.60 million of people
Step-by-step explanation:
We measure the time t in years and let t=0 in the year 1950.
We measure the population P(t) in millions of people, then P(0)=2560 and P(10) = 3040.
Since we are assuming that dp/dt=kP, this theorem gives the following.



The relative growth rate is about 1.7% per year and the model is

<em>Year 1991 is equal in our formula to 41 and year 2020 is equal to 70. </em>Replacing,


Therefore the populaton in year 1991 will be of 5178.9 million of people and the population in year 2020 will be of 8524.60 million of people
Use the points and do y2-y1 divided by x2-x1
You will get -2 which is the m (slope)
Substitute one of the points into the y and x to get the b (y-intercept)
You will get -6
Put everything into the equation
y=-2x-6
That is called the solution
factor is like 2 and 3 and 9 are factors of 18 because 2*9=18 and 3*6=18
inequality is like 3<4
product is multiplcation so like product of x and y is x times y
answer is solution
Answer:
D, the lines coincide.
Step-by-step explanation:
isolate the y so theres no 2y, only y:
2y = 8 - 2x (divide both sides by 2)
y = 4 - x
The lines are the same line, so while they are plural, they also coincide, as one lies on top of the other.
