Answer this in 2 steps:
1) Solve 3x+y=4 for y: 3x+y=4 becomes 3x-3x+y=4-3x, or y = -3x + 4.
1
2) Find the reciprocal of this result: 1/y = --------------
-3x + 4
Your answer is 3.5 which is 3 1/2

68. D
Step-by-step explanation:
I don't remember exactly the explanation, but I recommend you try to learn more about number lines sometime when you aren't under stress from schoolwork, because they're pretty simple questions to answer once you get a better understanding of them!
Answer:

Step-by-step explanation:
we know that
The total vertical distance (total miles North) traveled is equal to

Remember that


substitute


Answer:
t=2
Step-by-step explanation:
The slope is given by
m = (y2-y1)/(x2-x1)
We have points (3,10) and (5,t) and the slope is -4
Substituting these in
-4 = (t-10)/ (5-3)
Simplifying
-4 = (t-10) / 2
Multiply by 2 on both sides
-4 = (t-10) / 2 *2
-8 = t-10
Add 10 on both sides
-8+10 = t-10+10
2 = t
