Answer:
y<-2x-3
Step-by-step explanation:
Your first step is to find the equation of the line. You can see that the y-intercept is -3, therefore your b is -3. So now your formula looks like this:
y=mx-3
To find m, you substitute in an x value and its corresponding y value. When you do this you will get -2.
Now it looks like this:
y=-2x-3.
Now that you have the equation of the line, you can look at the inequality. Since the line is dotted, that means it is not included in the inequality. That mean it cannot contain an equal to. So the only options we have are < and >. Since the shaded area is to the left, which is the negative side, we can conclude that y<-2x-3 is the correct equation.

Answer:
Find out what x should be the apply by the power of 2 then you should be good
T1 + t2 = 2h and 30min;
t1 * 600 = t2 * 400 => t2 = (3/2) * t1;
then, t1 + (3/2) * t1 = 2h and 30min => 2t1 + 3t1 = 5h => 5*t1 = 5h => t1 = 1h => t2 = 1h and 30 min;
The distance is 2 * 1 * 600 = 1200miles;
Answer:
See below:
Step-by-step explanation:
If we do this, we know that 2 gallons takes 14 seconds. (2:14)
Based on that data, we can know that 1 gallon takes 7 seconds. (1:7)
-> 2/14 = 1/7
Now we can multiply by 12 to get 12 gallons on one side.
What we do on one side has to happen to the other side.
So, 12 gallons * 1 gallons = 12 gallons and 12 gallons * 7 gallons = 84 gallons.
So the final answer is 85 gallons,
Answer:
n= -9
Step-by-step explanation:
-3 ( n+5 ) = 12
-3n - 15 = 12
-3n = 12+15
-3n = 27
n = -27/3
n = -9
