Answer:
5x - 4y = 32
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
5x - 4y = 36 ( subtract 5x from both sides )
- 4y = - 5x + 36 ( divide all terms by - 4 )
y = x - 9 ← in slope- intercept form
with slope m =
Parallel lines have equal slopes, thus
y = x + c ← is the partial equation
To find c substitute (8, 2) into the partial equation
2 = 10 + c ⇒ c = 2 - 10 = - 8
y = x - 8 ← in slope- intercept form
Multiply through by 4
4y = 5x - 32 ( subtract 4y from both sides )
0 = 5x - 4y - 32 ( add 32 to both sides )
32 = 5x - 4y, that is
5x - 4y = 32 ← in standard form
All the factors of 12<span>. 2 × 6 = </span>12<span>, but also 3 × 4 = </span>12<span>, and of course 1 × </span>12<span> = </span>12<span>.</span>
Answer:2275000
Step-by-step explanation:
If out of 1000, 7 people are being affected. It means that (7/1000)*100= 0.7% of the population is being affected
Since USA poppulation is 325million, the affected people are 0.7% of 325 million
325000000*(0.7/100)= 2275000
Answer: Option A
Step-by-step explanation:
Note that for the initial year, 1990, the population was 5.3 billion.
The exchange rate is 0.09125 billion per year. In other words, each year there are 0.09125 billion more people.
In year 2 there will be 0.09125 * 2 billion people
In year 3 there will be 0.09125 * 3 billion people
In year 4 there will be 0.09125 * 4 billion people
In year t there will be 0.09125 * t billion of people
So the equation that models the number of people that there will be as a function of time is:
Where is the initial population
billion
r is the rate of increase
billion per year
finally the equation is:
The correct answer is option A.
