Step-by-step explanation:
please mark me as brainlest
Answer:
9
Step-by-step explanation:
This equation is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = 9x+5
The slope is 9
Parallel lines have the same slope so a line parallel would have a slope of 9
Let J = rate of jet in still airLet W = rate of wind Distance formula: d = rt / r = d/t Flying against the wind the jet flies at a rate of J - W = 1860 miles/3 hours = 620 miles per hourFlying with the wind the jet flies at a rate of J+W = 9180 miles/9 hours = 1020 miles per hour The average of these 2 rate is the speed of the jet in still air J = (620+1020)/2 = 820 miles per hour J - W = 620
820 - W = 620
W = 820 - 620 = 200 miles per hour The jet in still air flies at a rate of 820 mph(miles per hour)The wind speed is 200 mph(miles per hour)
Answer:
a) Linear
b) Linear
c) Linear
d) Neither
See explanation below.
Step-by-step explanation:
a) 
For this case the differential equation have the following general form:
Where 
and 
and since n>1 we can see that is a linear differential equation.
b) 
We can rewrite the following equation on this way:
For this case the differential equation have the following general form:
Where 
and 
and since n=0 we can see that is a linear differential equation.
c) 
For this case we can write the differential equation on this way:
For this case the differential equation have the following general form:
Where 
and 
and since n=0 we can see that is a linear differential equation.
d) 
For this case we can't express the differential equation in terms:
So the is not linear, and since we can separate the variables in order to integrate is not separable. So then the answer for this one is neither.
The solution to the system of equation is (1, 4).
In order to find this, we can first just see where the graphs intersect each other. This will give us the solution set.
As for what it represents, the x value in the increase in temperature and the y value is the increase in customers.
Therefore, we know that we want the temperature to go up by 1 (although we don't know the units) and that would result in the amount of people coming, and staying longer by 4 (again, we don't know the units of measure).
