Let's turn this into a fraction using the given information we already have.

We want the denominator, or the bottom part of the fraction, to be 1 in order for us to have a unit rate.
This fraction can be simplified if we divide both the numerator and denominator by 3.
Numerator: 18/3 = 6
Denominator: 3/3 = 1
Now we have

Any number divided by 1 is equal to that number.

Thus, your unit rate is 6 miles per hour.
Have an awesome day! :)

Answer:
See attached picture.
Step-by-step explanation:
To graph the linear equation, convert x+y=4 into y= -x+4. This means that y= mx+b is y=-x+4. So m = -1 and b =4.
Start with b by finding 4 on the y-axis. Plot a point. Then from this point move down 1 unit and 1 unit to the right to (1,3). Plot this point. Connect the points.
-.5x^2 = -6x + 20
-.25x = -6x + 20
+6x +6x
5.75x = 20
/5.75 /5.75
x = 3.48
Answers: m = 8

Answer:
y = -30
Option A
Step-by-step explanation:
y = -2x - 10
y = -5x + 20
We just need to substitute the values of y.
We have to equate both the equation.
-2x -10 = -5x + 20
-2x + 5x = 20 + 10
3x = 30
x = 10
Plug x as 10 in any one of the equation
Let's take the first equation
y = -2x - 10
y = -2(10) - 10
y = -20 -10
y = -30
