Answer:
y = -3x + 11
Step-by-step explanation:
To find the equation of the line we would plug in the given info into the point slope equation:
In this case (x1, y1) is (4, -1) and m is -3:
y - (-1) = -3(x - 4)
We can simplify as follows:
y + 1 = -3x + 12
y = -3x + 11
The distance Miranda drives between home and work is fixed, regardless of the direction of travel. Let's call this distance "d."
Then d = (0.5 hour)(r mph) = 0.5r miles.
But d also equals (0.75 hour)(v mph) = 0.75v miles
We cannot actually solve for r and v without more info; that info would be the actual distance traveled (as a number).
Answer:
18
Step-by-step explanation:
40/100 x 45 = 2/5 x 45 = 18
Step-by-step explanation:
Given
- 4( 3x - 5 ) > - 28
Dividing both sides by - 4 we get
3x - 5 > 7
Adding 5 on both sides we get
3x - 5 + 5 > 7 + 5
3x > 12
Dividing both sides by 3 we get
x > 4
